I have a UIView that displays lines, and I zoom in (scale by 2 on the scroll view zoomScale variable containing the UIView). As I zoom in, on the Mac version (Designed for IPad) I loose the graphic after a certain number of zooms (the scrollView maximumZoomScale is set at 10). To ensure that lines are correctly represented, I modify the contentScaleFactor variable on the UIView; otherwise, the line's display is pixelated. On the IPad (simulator and real) I do not loose the graphic when zooming. So the Mac port of the UIView drawing is not working as the IPad version. Everything else of the application works fine except this important details. I already submitted a feedback request (#FB16829106) with the images showing the problem. I need a solution to this problem. Thanks.

I am trying to install the Game Porting Toolkit 2.1 according to the Readme file provided with the toolkit. When I run the following command: WINEPREFIX=~/my-game-prefix brew --prefix game-porting-toolkit/bin/wine64 winecfg I get an error message: zsh: no such file or directory: /usr/local/opt/game-porting-toolkit/bin/wine64 I don't know how to resolve this. When I type in the command which brew , I get the path /usr/local/bin/brew What am I doing wrong?

Hi everyone, I'm using the Vision framework’s ImageAestheticsScoresObservation class (https://developer.apple.com/documentation/vision/imageaestheticsscoresobservation). I noticed that the overallScore returned sometimes gives negative values. Could someone confirm whether the expected range of the score is from -1.0 to 1.0? The documentation doesn’t explicitly state the possible score range, so I’d appreciate any clarification or insights. Thanks in advance!

So, I'm done with GPTK and decided to delete it. The only thing I installed was brew -v install apple/apple/game-porting-toolkit and the external libraries from the ditto command. Now, I tried to remove it, but even after brew remove game-porting-toolkit brew autoremove all of the dependencies installed with brew are still there. The most obvious was game-porting-toolkit-compiler, but even after removing this there are so many libraries that are now orphaned and it's just impossible to manually identify those. Is there a way or is the easiest way to simply uninstall Homebrew completely and reinstall it again?

I recently needed to develop an application to obtain the window list, which requires Screen Recording permissions. Apple's official documentation mentions using the two functions CGPreflightScreenCaptureAccess and CGRequestScreenCaptureAccess to request permissions. These functions are stated to be available since version 10.15. However, when I used these two functions on a device running macOS 10.15.7, I encountered the errors shown in the attached screenshot. I used the nm tool to inspect the symbols in the CoreGraphics.framework and found that these two functions were not present. Could you help me understand why this is happening?

Hi I've noticed one issue in Metal HUD, but I'm not sure if it is a bug in the Metal HUD or if there is a purpose for this behavior. Metal HUD has an option to send the data to system log in raw format where the numbers are like metal-HUD: ,,,,,..., https://developer.apple.com/documentation/xcode/monitoring-your-metal-apps-graphics-performance/ If the HUD is displayed, it works just fine, but it seems that when the HUD is hidden (with shift-F9), it still send the data to system log, but the numbers are the same all the time and are not updated while is still being updated. I would expect that it should log the data no matter if the HUD is displayed or not, this of course leads to incorrect FPS calculations Here is an example of the system log entries when the HUD is not visible:

We have a macOS app (not yet released, but in use by ourselves), that provides scoreboards for streaming sport events. Today it is expected, that there are nice animations for goals, etc. We are streaming using NDI, which requires a CVPixelBuffer for each frame. We currently create these animations using CABasicAnimation, CAAnimation and CAKeyframeAnimation. In addition we use ScreenCaptureKit to generate the frames. This works fine with 25/30 fps, as long as the window where our animations are performed in is visible. But this is not what it should be. We have a smaller window as main app window and control display performing the animations in reduced size, while the streaming animations need to be in HD format and later maybe in 4K. When using an offscreen window, the animations are not calculated. We get 1 frame per second or so. So we actually have to connect an external display to the MacBook and open the large windows there. Ugly solution. Do we use a completely wrong approach? Or is there a way to tell the macOS to perform the animations although it is an offscreen window? If it cannot work that way, what is an alternative?

I have code that captures a window and displays a cropped image. The problem is 2 fold. Kit doesn't seem to allow to modify stop and recapture image in window mode to capture a portion of the screen. So this makes me having to crop and display the cropped image via a published variable. This all works find. But seems to stop after some time. Using an M1 16gig ram. program is taking less than 100meg of mem with 40-70%cpu as the crow flies. printing captured success in debug mode and sometimes frame isn't valid so guarding against it. any ideas on how to improve my strategy?

Imagine a native macOS app that acts as a "launcher" for a Java game.** For example, the "launcher" app might use the Swift Process API or a similar method to run the java command line tool (lets assume the user has installed Java themselves) to run the game. I have seen How to Enable Game Mode. If the native launcher app's Info.plist has the following keys set: LSApplicationCategoryType set to public.app-category.games LSSupportsGameMode set to true (for macOS 26+) GCSupportsGameMode set to true The launcher itself can cause Game Mode to activate if the launcher is fullscreened. However, if the launcher opens a Java process that opens a window, then the Java window is fullscreened, Game Mode doesn't seem to activate. In this case activating Game Mode for the launcher itself is unnecessary, but you'd expect Game Mode to activate when the actual game in the Java window is fullscreened. Is there a way to get Game Mode to activate in the latter case? ** The concrete case I'm thinking of is a third-party Minecraft Java Edition launcher, but the issue can also be demonstrated in a sample project (FB13786152). It seems like the official Minecraft launcher is able to do this, though it's not clear how. (Is its bundle identifier hardcoded in the OS to allow for this? Changing a sample app's bundle identifier to be the same as the official Minecraft launcher gets the behavior I want, but obviously this is not a practical solution.)

Hi Apple & devs, I'm trying to test various Windows .exe files using the Game Porting Toolkit (GPTK), but I’m hitting a wall: no matter what .exe I try, the command returns instantly with no output — no error, no logs, nothing. Here's what I'm doing: I'm using macOS Sequioa 15.5 on M1 macbook pro. I installed gameportingtoolkt GPTK 2.1 through brew from gcenx: brew install gcenx/wine/game-porting-toolkit When I run any .exe using GPTK's wine64, like this, e.g. with steam user@JMacBook-Pro / % WINEPREFIX=~/wine_prefix /usr/local/bin/gameportingtoolkit 'C:\SteamSetup.exe' --verbose user@JMacBook-Pro / % Immediate exit without any return code, output, nor errors. No output, no crash, no logs. Same result with simple test apps Running with WINEDEBUG=+all (still no output) Even running wine64 does the same thing. I’ve tried: Removing and reinstalling GPTK Creating a fresh WINEPREFIX Checking /tmp and ~/Library/Logs for logs — nothing Has anyone else experienced this or have any idea how to debug it? Is there ANY Apple support for this?? Thanks in advance.

I just got the new iOS 26 beta, and I LOVE the games app, but it show all of my games, even from years back. Is there a way to remove games from your library on the app?

iPhone(14 Pro Max)で端末の画面にリフレッシュレートを表示させたいのですが、どなたか方法をご存知ないでしょうか？

App Storeにある『浮遊時計 Premium』は1Hzごとか10Hzごと、または3段階以上のリフレッシュレート計測はできますか？

Hello, MacOS 26 Betas are limiting games (noticeably, games that use java) to the native display of the MacBook Pro (120hz). Even connecting an external display this is not changing. I have submitted a bug report, but I have not had any responses to it yet. I am looking to see if anyone may have an answer or fix to this issue. Thanks!

Looks like is something to do with the code and that is why my images are distorted. please help me get to the right person to help me get this issue resolved

Hello, I found an issue with the Games app on macOS 26 (Tahoe) when viewing achievements: In App Store Connect, each achievement has different values set for the pre-earned description and the post-earned description. When testing with GameKit directly (GKAchievementDescription), both values are returned correctly. However, in the macOS Games app, the post-earned description is shown even before the achievement is earned. This seems to be a display issue specific to the Games app on macOS. Could you confirm if this is a known bug in the Games app, or if there is a reason why pre-earned descriptions are not being shown? Thank you.

Hello everyone and thank you for you're time! I got an issue with uploading several icons to testflight. I'm using Game Maker Studio as my engine for the game. This is the error that I'm getting, even when I try to use the old icons for the game, that worked in the past. I tried to transform the icons, using this site "https://makeappicon.com/", but I still got the same validation error. Can you help me fixing the issue - thank you so much!

My IOS app generates pdf files. Every time my users open the generated pdf files, the autofill popup jumps out, but my pdf file is NOT for interacting. I'm here to ask if there's a way to mark my pdf files as "not a form", like in metadata or anywhere else?

Hi, I have an Unity game. I need to have multiple App Icons for my game for it to be able to be recognized in different countries. In other words, is it possible to have an iOS app in which the App Icon changes based on device locale/language? On Android this is possible using Unity Localization package "com.unity.localization"
