Small Size Icons and NSToolbar on MacOS 12.0 Monterey -- can it work?
I noticing that Monterey defaults to the NSWindowToolbarStyleAutomatic / NSWindowToolbarStyleUnified toolbar style, which suppresses the "use Small Size" menu item and customization checkbox. So I've set the window to use NSWindowToolbarStyleExpanded. However, the toolbar will no longer change to a smaller icon size, as it did in MacOS 10.14, 10.15, and 11.0. I've tried to set the toolbar item sizing to "Automatic" for all of our toolbar icons, but that results in bad positioning in both Regular and Small Size mode -- the height is way too big. The native size of the icon .png files are 128 x 128. What's odd is that if I resize the window with the toolbar to be wider, the NSToolbarItems in the overflow area will be displayed in the toolbar are 128 x 128, where the rest of the toolbar icons get displayed as a 32 x 32 icon. The only way to get it to layout remotely correct is to make the NSToolbarItem to have an explicit minimum size of 24 x 24 and maximum size of 32 x 32. And that USED to allow "small size", but on Monterey, it no longer does. Anyone had any success with small size icons on Monterey?

Obscure assertion crash in com.apple.NSScrollingConcurrentVBLMonitor thread
I have received a few crash reports for my app "Find Any File" with an assertion failure as follows: assertion failure: "displayTiming != ((void *)0)" -> %lld Googling this turns up nothing, though. I wonder if someone has some insight into why this might happen, and how to prevent it. One reporting user suggests that it happens when my app shows a very long list of items in an NSTableView (>10000 elements). I have 4 reports from 3 users, and the main thread is doing something related to the table view each time, though not the same (the few other threads are all idle): Crash 1, in macOS 14.0 (23A344: Thread 0:: Dispatch queue: com.apple.main-thread 0 libobjc.A.dylib 0x182c69400 objc_msgSend + 0 1 AppKit 0x186f15400 -[CALayer(NSViewVisibleRect) NS_viewVisibleRectDidChange] + 40 2 AppKit 0x186900e10 NSViewHierarchyInvalidateVisibleRect + 276 3 AppKit 0x186900db0 NSViewHierarchyInvalidateVisibleRect + 180 4 AppKit 0x186900db0 NSViewHierarchyInvalidateVisibleRect + 180 5 AppKit 0x186900db0 NSViewHierarchyInvalidateVisibleRect + 180 6 AppKit 0x186900db0 NSViewHierarchyInvalidateVisibleRect + 180 7 AppKit 0x186900db0 NSViewHierarchyInvalidateVisibleRect + 180 8 AppKit 0x1869990e0 -[NSView translateOriginToPoint:] + 164 9 AppKit 0x186984108 -[NSClipView _immediateScrollToPoint:] + 420 10 AppKit 0x186983eb8 -[NSClipView scrollToPoint:] + 184 11 AppKit 0x186998d80 -[NSScrollView scrollClipView:toPoint:] + 84 12 AppKit 0x1869448dc -[NSClipView _scrollTo:animateScroll:flashScrollerKnobs:] + 480 13 AppKit 0x186b65b24 __62-[NSScrollingBehaviorConcurrentVBL _stopGestureScrollTracking]_block_invoke + 192 14 AppKit 0x186e6a6e8 ___NSMainRunLoopPerformBlockInModes_block_invoke + 44 15 CoreFoundation 0x18310b8c0 __CFRUNLOOP_IS_CALLING_OUT_TO_A_BLOCK__ + 28 Crash 2, in macOS 14.1.1 (23B81): Thread 0:: Dispatch queue: com.apple.main-thread 0 CoreFoundation 0x18ba401f4 DYLD-STUB$$_Block_object_assign + 0 1 libsystem_blocks.dylib 0x18b506118 _call_copy_helpers_excp + 80 2 libsystem_blocks.dylib 0x18b505c68 _Block_copy + 376 3 libdispatch.dylib 0x18b641c7c _dispatch_Block_copy + 32 4 libdispatch.dylib 0x18b658df0 _dispatch_source_set_handler + 92 5 CoreFoundation 0x18b99e1e4 __CFRunLoopCopyMode + 540 6 CoreFoundation 0x18b8b7458 CFRunLoopAddObserver + 220 7 AppKit 0x18f0a687c _PerfAddRunLoopObserver + 192 8 AppKit 0x18f87cd60 -[NSApplication(NSEventRouting) _nextEventMatchingEventMask:untilDate:inMode:dequeue:] + 368 9 AppKit 0x18f323318 -[_NSScrollingConcurrentEventMonitor startMonitoring] + 380 10 AppKit 0x18f321df8 -[NSScrollingBehaviorConcurrentVBL _scrollView:trackGestureScrollWithEvent:] + 884 11 AppKit 0x18f2e67f8 -[NSScrollingBehaviorConcurrentVBL scrollView:scrollWheelWithEvent:] + 512 12 AppKit 0x18f241770 forwardMethod + 252 13 AppKit 0x18f2e62a0 -[NSView scrollWheel:] + 408 14 AppKit 0x18f241770 forwardMethod + 252 15 AppKit 0x18f2e62a0 -[NSView scrollWheel:] + 408 16 AppKit 0x18f241770 forwardMethod + 252 17 AppKit 0x18f2e62a0 -[NSView scrollWheel:] + 408 18 AppKit 0x18f241770 forwardMethod + 252 19 AppKit 0x18f2e62a0 -[NSView scrollWheel:] + 408 20 AppKit 0x18fc45880 -[NSCollectionView scrollWheel:] + 180 21 AppKit 0x18f241770 forwardMethod + 252 22 AppKit 0x18f241770 forwardMethod + 252 23 AppKit 0x18f2e62a0 -[NSView scrollWheel:] + 408 24 AppKit 0x18f241770 forwardMethod + 252 25 AppKit 0x18f2e62a0 -[NSView scrollWheel:] + 408 26 AppKit 0x18f241770 forwardMethod + 252 27 AppKit 0x18f2e62a0 -[NSView scrollWheel:] + 408 28 AppKit 0x18f1d27b0 -[NSWindow(NSEventRouting) _reallySendEvent:isDelayedEvent:] + 652 As you can see, there's no code of mine involved at the time of crash.

NSScrollView two finger drag being interrupted
I have a fairly robust MacOS application that has an NSScrollView that contains a canvas with various subviews (including web views and text views that contain scroll views), and a couple of peer views that track items in the scroll view (eg: screen space controls). Some of these views interrupt two finger scrolling. Every scroll view, and one of the peer views (essentially a stack view with buttons in it). I have written an additional bare bones application which does roughly the same thing, and my bare bones application works perfectly: Start two-finger dragging, scroll any of these other things under the cursor, I can continue to drag (and start dragging in any of those, and they drag without interfering with the parent scroll view). I have tried everything to recreate the interruption, including drag gestures attached to these various ancillary views, and I cannot figure out why dragging some of these views under the cursor interrupts two finger drag in our application, but not in my testbed. Does anyone have suggestions for how to debug this? I can see that there is a gesture recognizer in the NSScrollView hierarchy, but I don't see it in any of my gesture recognizer handling. I have breakpoints on every variation of hit testing and mouse motion, and none of them are getting hit in unexpected ways. I'm at my wit's end. Thanks.

NSSavePanel accessory view doesn't react to enter keypress
I have a textfield in accessory view of NSSavePanel. For user convenience there are default actions supported natively by macOS (such as pressing Enter, keyEquivalent). However this doesn't work for enter under Sonoma. Escape key works. Is enter keypress dangerous for malicious actors so it's not supported? I have workaround below but I am not confident if I am not violating sandbox (future proof). Original code demonstrating the issue: class ViewController: NSViewController, NSTextFieldDelegate, NSControlTextEditingDelegate { let savePanel = NSSavePanel() override func viewDidLoad() { super.viewDidLoad() let customView = NSView() let textField = NSTextField(string: "11111111") textField.delegate = self // to get focus using tab keypress savePanel.accessoryView = textField } override func viewWillAppear() { savePanel.runModal() } } Workaround: // variable set to true in delegate method controlTextDidEndEditing var didUseTextFieldWithEnterPressed = false override func performKeyEquivalent(with event: NSEvent) -> Bool { if #unavailable(macOS 14) { return super.performKeyEquivalent(with: event) } guard let panel, didUseTextFieldWithEnterPressed == true, event.type == .keyDown && (event.keyCode == UInt16(kVK_Return) || event.keyCode == UInt16(kVK_ANSI_KeypadEnter)) else { return super.performKeyEquivalent(with: event) } return panel.performKeyEquivalent(with: event) }

Cannot remove an observer <TUINSCursorUIController 0x600001844340> for the key path "visible" from <NSSavePanel 0x10ff05200> because it is not registered as an observer.
I have two NSTextField as an accessoryView of NSSavePanel. When I try to change focus in between them with a caps lock on the whole panel will crash. This will also happen when NSTextField if focused with caps lock on and i press cmd+tab (app switching). This happens on Sonoma + Sequoia beta. On top I have noticed editing NSTextField in accessoryView is completely broken on Sonoma and I can only edit it ONLY when the textfiled is using bindings. I am trying to find a workaround for the caps lock indicator being displayed. The only idea I have ATM is to observe NSApp.windows and look for TUINSWindow and force close it when it's visible. Is there any other workaround to prevent this crash? https://youtu.be/BCVjZH7684U Sample code: import Cocoa class ViewController: NSViewController { let savePanel = NSSavePanel() override func viewDidLoad() { super.viewDidLoad() let view = NSGridView(views: [[NSTextField(string: "111111")], [NSTextField(string: "22222222")]]) savePanel.accessoryView = view } override func viewWillAppear() { savePanel.runModal() } } Crash report: Cannot remove an observer <TUINSCursorUIController 0x600001844340> for the key path "visible" from <NSSavePanel 0x10ff05200> because it is not registered as an observer.

NSMutableAttributedString and NSTextTable
I'm using NSTextTable to format panels of stand-out text within body text. Paragraphs within the panel are handled as individual NSTextTableBlocks within the table. Each block is added to the NSMutableParagraphStyle that is part of the attributed string within the block's attributes. That's all fine and it works. But... Occasionally I see undrawn lines within the panel. These disappear (or sometimes appear) when the parent window (and thus the NSTextView holding the rendered attributed string) is resized. Lines do not always appear, and when they do they are not always in the same place. The height of the gap varies. I see this behaviour with these panels and with tables. What's common to both cases is not only the use of NSTextTable and NSTextTableBlock etc., but crucially (I think) the use of block margins. If I disable margins (which looks OK for the panels, but isn't right for tables), the problem disappears. So, a bug or (more likely) I'm missing a key part of view rendering or margin set up. But what? Code here: https://github.com/smittytone/PreviewMarkdown/blob/930f5f32aa0b3b77ec3f4f53436a79e10bb26f18/Markdown%20Previewer/Styler.swift#L882 Running 14.6.1 on an M3. I'm using TextKit 1 because I'm using an NSLayoutManager subclass to override certain text underlines (not used in panels as outlined above, or tables).

[macOS Sequoia] Using RegisterEventHotkey with option and shift modifiers doesn't working anymore
Hello. In my app, I use RegisterEventHotkey to implement global keyboard shortcuts to trigger actions. Up until macOS Sequoia, I was able to use a keyboard shortcut with option and shift as the modifiers, like option shift 2 (⌥ ⇧ 2). Now, on macOS Sequoia, using RegisterEventHotkey to register a hotkey with those exact modifiers (option and shift), regardless of the key, fails with the error -9868 (eventInternalErr). Is this a documented and wanted change, or is this a bug? Other modifier keys (just command, command option, command shift, command control, control shift, etc), all work. Any insight into this would be appreciated. (Feedback filed: FB15163561) Thank you, Matthias

NSScrollView scrolling hitch
When scrolling a basic NSScrollView there seems to be a sudden jump after each flick. Scrolling does not appear smooth and is disorientating. A scroll jump seems to happen directly after letting go of a scroll flick using a trackpad/mouse. Right at that moment the scroll turns into a momentum scroll, slowly decreasing the speed. But the first frame after the gesture the content jumps forward, more than what is expected. Observations: Counterintuitively, scrolling appears to be smoother when disabling NSScrollView.isCompatibleWithResponsiveScrolling. If disabled using a custom NSScrollView subclass there is no large jump anymore. Scrolling also appears to be smoother using a SwiftUI ScrollView. I assume that has the same behaviour as a disabled isCompatibleWithResponsiveScrolling Ironically a WKWebView scrolls much smoother. No sudden jump is observable. It also seems to scroll with faster acceleration, but the individual frames do appear smoother. Why is this better than a native NSScrollView? Elastic scrolling at the bounds of the scroll view also appears much smoother for WKWebViews. When pulling to refresh there is a jump for NSScrollView/SwiftUI, but not for WKWebView. When using an NSScrollView with isCompatibleWithResponsiveScrolling disabled, scrolling appears just as smooth as WKWebView on macOS 13 Ventura and below. On macOS 14 Sonoma scrolling behaviour is suddenly different. Please see a sample project with 4 different scroll views side by side: https://github.com/floorish/ScrollTest Screen recordings show the sudden jumps when scrolling and when elastic scrolling. Tested on Intel & Arm Macs, macOS 11 Big Sur through 15 Sequoia, built with Xcode 16. Should isCompatibleWithResponsiveScrolling be disabled on Sonoma+? Are there any drawbacks? There is also no overdraw anymore since Monterey, as described in https://developer.apple.com/library/archive/releasenotes/AppKit/RN-AppKitOlderNotes/#10_9Scrolling Even with responsive scrolling disabled, why is WKWebView scrolling much smoother than NSScrollView?

Crash when assigning NSImage to `@objc dynamic var` property
Xcode downloaded a crash report for my app which I don't quite understand. It seems the following line caused the crash: myEntity.image = newImage where myEntity is of type MyEntity: class MyEntity: NSObject, Identifiable { @objc dynamic var image: NSImage! ... } The code is called on the main thread. According to the crash report, thread 0 makes that assignment, and at the same time thread 16 is calling [NSImageView asynchronousPreparation:prepareResultUsingParameters:]. What could cause such a crash? Could I be doing something wrong or is this a bug in macOS? crash.crash

Force NSDocument save panel to select most specific type in format popup button
My app supports different plain text file formats, including the standard .txt and Markdown. When creating a new document, my app already asks which format it should have, so when saving it, I would expect that the save panel already selects that format in the popup button, but currently it always selects "Plain Text". For example, I would expect for a Markdown document that it selects "Markdown" instead of "Plain Text". Is there a way to force it to select the most specific format matching the document format?

NSTextView.shouldDrawInsertionPoint doesn't work with TextKit 2
The following code only ever causes shouldDrawInsertionPoint to be printed (no drawInsertionPoint), but even if that method returns false, the blinking insertion point is still drawn. On the other hand, with TextKit 1 it works as expected. Is there a way to hide the default insertion point in TextKit 2? My app draws its own. I've filed FB13684251. class TextView: NSTextView { override var shouldDrawInsertionPoint: Bool { print("shouldDrawInsertionPoint") return false } override func drawInsertionPoint(in rect: NSRect, color: NSColor, turnedOn flag: Bool) { print("drawInsertionPoint", flag) } } ``

NSToolbar doesn't restore displayMode when NSWindow.titleVisibility = .hidden
Apparently when setting a window to hide its title, the toolbar's displayMode is not restored when relaunching the app. For example, by default my app sets to show toolbar icons only, but when right-clicking it, selecting "Icon and Text" and relaunching the app, it's again "Icon Only". Is there a workaround? I've filed FB17144212. class ViewController: NSViewController, NSToolbarDelegate { override func viewDidAppear() { let toolbar = NSToolbar(identifier: "toolbar") toolbar.delegate = self toolbar.autosavesConfiguration = true toolbar.displayMode = .iconOnly view.window?.titleVisibility = .hidden view.window?.toolbar = toolbar view.window?.toolbarStyle = .unified } func toolbarAllowedItemIdentifiers(_ toolbar: NSToolbar) -> [NSToolbarItem.Identifier] { return [.init(rawValue: "item")] } func toolbarDefaultItemIdentifiers(_ toolbar: NSToolbar) -> [NSToolbarItem.Identifier] { return [.init(rawValue: "item")] } func toolbar(_ toolbar: NSToolbar, itemForItemIdentifier itemIdentifier: NSToolbarItem.Identifier, willBeInsertedIntoToolbar flag: Bool) -> NSToolbarItem? { let item = NSToolbarItem(itemIdentifier: itemIdentifier) item.image = NSImage(named: NSImage.addTemplateName)! item.label = "item" return item } }

Overriding NSDocument.prepareSavePanel(_:) hides file format popup button
I would like to provide a default filename when saving a document depending on the document data. I thought I could do so by overriding NSDocument.prepareSavePanel(_:) and setting NSSavePanel.nameFieldStringValue, but simply implementing that method seems to hide the file format popup button shown by default (see image). Calling super doesn't help. Is it possible to set a default filename and keep the file format popup button? On macOS 15, I can toggle NSSavePanel.showsContentTypes, but how about macOS 14 and older?

However, this issue seems like a known issue with apple's Korean IME. There are many threads in Korean community about the same problem with Non-Qt apps. If this issue is a really Qt issue, feel free to open it again. Is there any workaround to fix this IME bug ? Thanks, Ted

-applicationDockMenu: method on NSApplicationDelegate doesn't work when attached to debugger
When I add a simple menu to the dock via the NSApplicationDelegate method -applicationDockMenu: and run the app from Xcode it doesn't work. -(NSMenu*)applicationDockMenu:(NSApplication*)sender { NSMenu *dockMenu = [self buildDockMenu]; if (dockMenu != nil) { NSLog(@"Returning dock menu."); return dockMenu; } else { NSLog(@"Not ready to build dock menu"); return nil; } } When I run the app, my main app window shows up but nothing logs out in -applicationDockMenu: until I click outside my app's window (so if I click the desktop background, or a Finder window, or whatever). Then after I click outside my app's main window this logs out: Returning dock menu. The "Not ready to build dock menu" message does not log out. But...when I right click on the dock icon, the menu doesn't show up. But if I stop the app from Xcode and just run it not attached to the debugger, the dock menu does show up. But this makes the debugging/testing situation not ideal.

I noticing that Monterey defaults to the NSWindowToolbarStyleAutomatic / NSWindowToolbarStyleUnified toolbar style, which suppresses the "use Small Size" menu item and customization checkbox. So I've set the window to use NSWindowToolbarStyleExpanded. However, the toolbar will no longer change to a smaller icon size, as it did in MacOS 10.14, 10.15, and 11.0. I've tried to set the toolbar item sizing to "Automatic" for all of our toolbar icons, but that results in bad positioning in both Regular and Small Size mode -- the height is way too big. The native size of the icon .png files are 128 x 128. What's odd is that if I resize the window with the toolbar to be wider, the NSToolbarItems in the overflow area will be displayed in the toolbar are 128 x 128, where the rest of the toolbar icons get displayed as a 32 x 32 icon. The only way to get it to layout remotely correct is to make the NSToolbarItem to have an explicit minimum size of 24 x 24 and maximum size of 32 x 32. And that USED to allow "small size", but on Monterey, it no longer does. Anyone had any success with small size icons on Monterey?

Is it possible to use UITextView in #TextKit2 with a subclass of NSTextContentManager without using NSTextStorage as backing store?
When I tried this, the app crashed immediately with a requirement to use NSTextContentStorage subclass

NSTrackingEnabledDuringMouseDrag broken in Ventura
In macOS 13.2, the NSTrackingEnabledDuringMouseDrag flag for NSTrackingArea is broken, i.e., mouse-entered and mouse-exited events are not sent during a drag. This problem did not exist in macOS 12. I've filed a bug report, FB11973492, just wondering if anyone knows a workaround.

Obscure assertion crash in com.apple.NSScrollingConcurrentVBLMonitor thread
I have received a few crash reports for my app "Find Any File" with an assertion failure as follows: assertion failure: "displayTiming != ((void *)0)" -&gt; %lld Googling this turns up nothing, though. I wonder if someone has some insight into why this might happen, and how to prevent it. One reporting user suggests that it happens when my app shows a very long list of items in an NSTableView (&gt;10000 elements). I have 4 reports from 3 users, and the main thread is doing something related to the table view each time, though not the same (the few other threads are all idle): Crash 1, in macOS 14.0 (23A344: Thread 0:: Dispatch queue: com.apple.main-thread 0 libobjc.A.dylib 0x182c69400 objc_msgSend + 0 1 AppKit 0x186f15400 -[CALayer(NSViewVisibleRect) NS_viewVisibleRectDidChange] + 40 2 AppKit 0x186900e10 NSViewHierarchyInvalidateVisibleRect + 276 3 AppKit 0x186900db0 NSViewHierarchyInvalidateVisibleRect + 180 4 AppKit 0x186900db0 NSViewHierarchyInvalidateVisibleRect + 180 5 AppKit 0x186900db0 NSViewHierarchyInvalidateVisibleRect + 180 6 AppKit 0x186900db0 NSViewHierarchyInvalidateVisibleRect + 180 7 AppKit 0x186900db0 NSViewHierarchyInvalidateVisibleRect + 180 8 AppKit 0x1869990e0 -[NSView translateOriginToPoint:] + 164 9 AppKit 0x186984108 -[NSClipView _immediateScrollToPoint:] + 420 10 AppKit 0x186983eb8 -[NSClipView scrollToPoint:] + 184 11 AppKit 0x186998d80 -[NSScrollView scrollClipView:toPoint:] + 84 12 AppKit 0x1869448dc -[NSClipView _scrollTo:animateScroll:flashScrollerKnobs:] + 480 13 AppKit 0x186b65b24 __62-[NSScrollingBehaviorConcurrentVBL _stopGestureScrollTracking]_block_invoke + 192 14 AppKit 0x186e6a6e8 ___NSMainRunLoopPerformBlockInModes_block_invoke + 44 15 CoreFoundation 0x18310b8c0 __CFRUNLOOP_IS_CALLING_OUT_TO_A_BLOCK__ + 28 Crash 2, in macOS 14.1.1 (23B81): Thread 0:: Dispatch queue: com.apple.main-thread 0 CoreFoundation 0x18ba401f4 DYLD-STUB$$_Block_object_assign + 0 1 libsystem_blocks.dylib 0x18b506118 _call_copy_helpers_excp + 80 2 libsystem_blocks.dylib 0x18b505c68 _Block_copy + 376 3 libdispatch.dylib 0x18b641c7c _dispatch_Block_copy + 32 4 libdispatch.dylib 0x18b658df0 _dispatch_source_set_handler + 92 5 CoreFoundation 0x18b99e1e4 __CFRunLoopCopyMode + 540 6 CoreFoundation 0x18b8b7458 CFRunLoopAddObserver + 220 7 AppKit 0x18f0a687c _PerfAddRunLoopObserver + 192 8 AppKit 0x18f87cd60 -[NSApplication(NSEventRouting) _nextEventMatchingEventMask:untilDate:inMode:dequeue:] + 368 9 AppKit 0x18f323318 -[_NSScrollingConcurrentEventMonitor startMonitoring] + 380 10 AppKit 0x18f321df8 -[NSScrollingBehaviorConcurrentVBL _scrollView:trackGestureScrollWithEvent:] + 884 11 AppKit 0x18f2e67f8 -[NSScrollingBehaviorConcurrentVBL scrollView:scrollWheelWithEvent:] + 512 12 AppKit 0x18f241770 forwardMethod + 252 13 AppKit 0x18f2e62a0 -[NSView scrollWheel:] + 408 14 AppKit 0x18f241770 forwardMethod + 252 15 AppKit 0x18f2e62a0 -[NSView scrollWheel:] + 408 16 AppKit 0x18f241770 forwardMethod + 252 17 AppKit 0x18f2e62a0 -[NSView scrollWheel:] + 408 18 AppKit 0x18f241770 forwardMethod + 252 19 AppKit 0x18f2e62a0 -[NSView scrollWheel:] + 408 20 AppKit 0x18fc45880 -[NSCollectionView scrollWheel:] + 180 21 AppKit 0x18f241770 forwardMethod + 252 22 AppKit 0x18f241770 forwardMethod + 252 23 AppKit 0x18f2e62a0 -[NSView scrollWheel:] + 408 24 AppKit 0x18f241770 forwardMethod + 252 25 AppKit 0x18f2e62a0 -[NSView scrollWheel:] + 408 26 AppKit 0x18f241770 forwardMethod + 252 27 AppKit 0x18f2e62a0 -[NSView scrollWheel:] + 408 28 AppKit 0x18f1d27b0 -[NSWindow(NSEventRouting) _reallySendEvent:isDelayedEvent:] + 652 As you can see, there's no code of mine involved at the time of crash.

So, there seems to be no 3rd party ext involved. I've attached a full report as well. Full report of Crash 1

NSScrollView two finger drag being interrupted
I have a fairly robust MacOS application that has an NSScrollView that contains a canvas with various subviews (including web views and text views that contain scroll views), and a couple of peer views that track items in the scroll view (eg: screen space controls). Some of these views interrupt two finger scrolling. Every scroll view, and one of the peer views (essentially a stack view with buttons in it). I have written an additional bare bones application which does roughly the same thing, and my bare bones application works perfectly: Start two-finger dragging, scroll any of these other things under the cursor, I can continue to drag (and start dragging in any of those, and they drag without interfering with the parent scroll view). I have tried everything to recreate the interruption, including drag gestures attached to these various ancillary views, and I cannot figure out why dragging some of these views under the cursor interrupts two finger drag in our application, but not in my testbed. Does anyone have suggestions for how to debug this? I can see that there is a gesture recognizer in the NSScrollView hierarchy, but I don't see it in any of my gesture recognizer handling. I have breakpoints on every variation of hit testing and mouse motion, and none of them are getting hit in unexpected ways. I'm at my wit's end. Thanks.

NSSavePanel accessory view doesn't react to enter keypress
I have a textfield in accessory view of NSSavePanel. For user convenience there are default actions supported natively by macOS (such as pressing Enter, keyEquivalent). However this doesn't work for enter under Sonoma. Escape key works. Is enter keypress dangerous for malicious actors so it's not supported? I have workaround below but I am not confident if I am not violating sandbox (future proof). Original code demonstrating the issue: class ViewController: NSViewController, NSTextFieldDelegate, NSControlTextEditingDelegate { let savePanel = NSSavePanel() override func viewDidLoad() { super.viewDidLoad() let customView = NSView() let textField = NSTextField(string: "11111111") textField.delegate = self // to get focus using tab keypress savePanel.accessoryView = textField } override func viewWillAppear() { savePanel.runModal() } } Workaround: // variable set to true in delegate method controlTextDidEndEditing var didUseTextFieldWithEnterPressed = false override func performKeyEquivalent(with event: NSEvent) -> Bool { if #unavailable(macOS 14) { return super.performKeyEquivalent(with: event) } guard let panel, didUseTextFieldWithEnterPressed == true, event.type == .keyDown && (event.keyCode == UInt16(kVK_Return) || event.keyCode == UInt16(kVK_ANSI_KeypadEnter)) else { return super.performKeyEquivalent(with: event) } return panel.performKeyEquivalent(with: event) }

Cannot remove an observer <TUINSCursorUIController 0x600001844340> for the key path "visible" from <NSSavePanel 0x10ff05200> because it is not registered as an observer.
I have two NSTextField as an accessoryView of NSSavePanel. When I try to change focus in between them with a caps lock on the whole panel will crash. This will also happen when NSTextField if focused with caps lock on and i press cmd+tab (app switching). This happens on Sonoma + Sequoia beta. On top I have noticed editing NSTextField in accessoryView is completely broken on Sonoma and I can only edit it ONLY when the textfiled is using bindings. I am trying to find a workaround for the caps lock indicator being displayed. The only idea I have ATM is to observe NSApp.windows and look for TUINSWindow and force close it when it's visible. Is there any other workaround to prevent this crash? https://youtu.be/BCVjZH7684U Sample code: import Cocoa class ViewController: NSViewController { let savePanel = NSSavePanel() override func viewDidLoad() { super.viewDidLoad() let view = NSGridView(views: [[NSTextField(string: "111111")], [NSTextField(string: "22222222")]]) savePanel.accessoryView = view } override func viewWillAppear() { savePanel.runModal() } } Crash report: Cannot remove an observer <TUINSCursorUIController 0x600001844340> for the key path "visible" from <NSSavePanel 0x10ff05200> because it is not registered as an observer.

NSMutableAttributedString and NSTextTable
I'm using NSTextTable to format panels of stand-out text within body text. Paragraphs within the panel are handled as individual NSTextTableBlocks within the table. Each block is added to the NSMutableParagraphStyle that is part of the attributed string within the block's attributes. That's all fine and it works. But... Occasionally I see undrawn lines within the panel. These disappear (or sometimes appear) when the parent window (and thus the NSTextView holding the rendered attributed string) is resized. Lines do not always appear, and when they do they are not always in the same place. The height of the gap varies. I see this behaviour with these panels and with tables. What's common to both cases is not only the use of NSTextTable and NSTextTableBlock etc., but crucially (I think) the use of block margins. If I disable margins (which looks OK for the panels, but isn't right for tables), the problem disappears. So, a bug or (more likely) I'm missing a key part of view rendering or margin set up. But what? Code here: https://github.com/smittytone/PreviewMarkdown/blob/930f5f32aa0b3b77ec3f4f53436a79e10bb26f18/Markdown%20Previewer/Styler.swift#L882 Running 14.6.1 on an M3. I'm using TextKit 1 because I'm using an NSLayoutManager subclass to override certain text underlines (not used in panels as outlined above, or tables).

[macOS Sequoia] Using RegisterEventHotkey with option and shift modifiers doesn't working anymore
Hello. In my app, I use RegisterEventHotkey to implement global keyboard shortcuts to trigger actions. Up until macOS Sequoia, I was able to use a keyboard shortcut with option and shift as the modifiers, like option shift 2 (⌥ ⇧ 2). Now, on macOS Sequoia, using RegisterEventHotkey to register a hotkey with those exact modifiers (option and shift), regardless of the key, fails with the error -9868 (eventInternalErr). Is this a documented and wanted change, or is this a bug? Other modifier keys (just command, command option, command shift, command control, control shift, etc), all work. Any insight into this would be appreciated. (Feedback filed: FB15163561) Thank you, Matthias

NSScrollView scrolling hitch
When scrolling a basic NSScrollView there seems to be a sudden jump after each flick. Scrolling does not appear smooth and is disorientating. A scroll jump seems to happen directly after letting go of a scroll flick using a trackpad/mouse. Right at that moment the scroll turns into a momentum scroll, slowly decreasing the speed. But the first frame after the gesture the content jumps forward, more than what is expected. Observations: Counterintuitively, scrolling appears to be smoother when disabling NSScrollView.isCompatibleWithResponsiveScrolling. If disabled using a custom NSScrollView subclass there is no large jump anymore. Scrolling also appears to be smoother using a SwiftUI ScrollView. I assume that has the same behaviour as a disabled isCompatibleWithResponsiveScrolling Ironically a WKWebView scrolls much smoother. No sudden jump is observable. It also seems to scroll with faster acceleration, but the individual frames do appear smoother. Why is this better than a native NSScrollView? Elastic scrolling at the bounds of the scroll view also appears much smoother for WKWebViews. When pulling to refresh there is a jump for NSScrollView/SwiftUI, but not for WKWebView. When using an NSScrollView with isCompatibleWithResponsiveScrolling disabled, scrolling appears just as smooth as WKWebView on macOS 13 Ventura and below. On macOS 14 Sonoma scrolling behaviour is suddenly different. Please see a sample project with 4 different scroll views side by side: https://github.com/floorish/ScrollTest Screen recordings show the sudden jumps when scrolling and when elastic scrolling. Tested on Intel & Arm Macs, macOS 11 Big Sur through 15 Sequoia, built with Xcode 16. Should isCompatibleWithResponsiveScrolling be disabled on Sonoma+? Are there any drawbacks? There is also no overdraw anymore since Monterey, as described in https://developer.apple.com/library/archive/releasenotes/AppKit/RN-AppKitOlderNotes/#10_9Scrolling Even with responsive scrolling disabled, why is WKWebView scrolling much smoother than NSScrollView?

Crash when assigning NSImage to `@objc dynamic var` property
Xcode downloaded a crash report for my app which I don't quite understand. It seems the following line caused the crash: myEntity.image = newImage where myEntity is of type MyEntity: class MyEntity: NSObject, Identifiable { @objc dynamic var image: NSImage! ... } The code is called on the main thread. According to the crash report, thread 0 makes that assignment, and at the same time thread 16 is calling [NSImageView asynchronousPreparation:prepareResultUsingParameters:]. What could cause such a crash? Could I be doing something wrong or is this a bug in macOS? crash.crash

Force NSDocument save panel to select most specific type in format popup button
My app supports different plain text file formats, including the standard .txt and Markdown. When creating a new document, my app already asks which format it should have, so when saving it, I would expect that the save panel already selects that format in the popup button, but currently it always selects "Plain Text". For example, I would expect for a Markdown document that it selects "Markdown" instead of "Plain Text". Is there a way to force it to select the most specific format matching the document format?

NSTextView.shouldDrawInsertionPoint doesn't work with TextKit 2
The following code only ever causes shouldDrawInsertionPoint to be printed (no drawInsertionPoint), but even if that method returns false, the blinking insertion point is still drawn. On the other hand, with TextKit 1 it works as expected. Is there a way to hide the default insertion point in TextKit 2? My app draws its own. I've filed FB13684251. class TextView: NSTextView { override var shouldDrawInsertionPoint: Bool { print("shouldDrawInsertionPoint") return false } override func drawInsertionPoint(in rect: NSRect, color: NSColor, turnedOn flag: Bool) { print("drawInsertionPoint", flag) } } ``

NSToolbar doesn't restore displayMode when NSWindow.titleVisibility = .hidden
Apparently when setting a window to hide its title, the toolbar's displayMode is not restored when relaunching the app. For example, by default my app sets to show toolbar icons only, but when right-clicking it, selecting "Icon and Text" and relaunching the app, it's again "Icon Only". Is there a workaround? I've filed FB17144212. class ViewController: NSViewController, NSToolbarDelegate { override func viewDidAppear() { let toolbar = NSToolbar(identifier: "toolbar") toolbar.delegate = self toolbar.autosavesConfiguration = true toolbar.displayMode = .iconOnly view.window?.titleVisibility = .hidden view.window?.toolbar = toolbar view.window?.toolbarStyle = .unified } func toolbarAllowedItemIdentifiers(_ toolbar: NSToolbar) -> [NSToolbarItem.Identifier] { return [.init(rawValue: "item")] } func toolbarDefaultItemIdentifiers(_ toolbar: NSToolbar) -> [NSToolbarItem.Identifier] { return [.init(rawValue: "item")] } func toolbar(_ toolbar: NSToolbar, itemForItemIdentifier itemIdentifier: NSToolbarItem.Identifier, willBeInsertedIntoToolbar flag: Bool) -> NSToolbarItem? { let item = NSToolbarItem(itemIdentifier: itemIdentifier) item.image = NSImage(named: NSImage.addTemplateName)! item.label = "item" return item } }

Overriding NSDocument.prepareSavePanel(_:) hides file format popup button
I would like to provide a default filename when saving a document depending on the document data. I thought I could do so by overriding NSDocument.prepareSavePanel(_:) and setting NSSavePanel.nameFieldStringValue, but simply implementing that method seems to hide the file format popup button shown by default (see image). Calling super doesn't help. Is it possible to set a default filename and keep the file format popup button? On macOS 15, I can toggle NSSavePanel.showsContentTypes, but how about macOS 14 and older?

-applicationDockMenu: method on NSApplicationDelegate doesn't work when attached to debugger
When I add a simple menu to the dock via the NSApplicationDelegate method -applicationDockMenu: and run the app from Xcode it doesn't work. -(NSMenu*)applicationDockMenu:(NSApplication*)sender { NSMenu *dockMenu = [self buildDockMenu]; if (dockMenu != nil) { NSLog(@"Returning dock menu."); return dockMenu; } else { NSLog(@"Not ready to build dock menu"); return nil; } } When I run the app, my main app window shows up but nothing logs out in -applicationDockMenu: until I click outside my app's window (so if I click the desktop background, or a Finder window, or whatever). Then after I click outside my app's main window this logs out: Returning dock menu. The "Not ready to build dock menu" message does not log out. But...when I right click on the dock icon, the menu doesn't show up. But if I stop the app from Xcode and just run it not attached to the debugger, the dock menu does show up. But this makes the debugging/testing situation not ideal.

Room Plan Issue (structure.capturedStructure)
Hi everyone, My app crashed when using the merge room feature. I suspect the issue might be caused by a wall having more than 4 edges. Has anyone experienced a similar problem and found a solution? I’d really appreciate any advice or suggestions. Thank you all, and have a great day! let capturedStructure = try await structure.capturedStructure(from: self.rooms)
