Reply to Supported way to expose an iPhone+controller as a macOS gamepad without restricted entitlements?
I will go ahead and file a request for a Core HID development variant. Perfect, thank you. FYI, I can't guarantee anything will change, but I'd like to get this sorted out as soon as possible, so this might be working relatively soon (at least on paid accounts). One comment here: More broadly, I think it would be very valuable to have a simple user-space API for controller virtualization available to hobbyists and personal developers as well, even if limited to development builds. I've seen a few requests asking about providing this support to the free account tier, not just the paid tier. It's a reasonable suggestion, but I did want to explain that the main reason the development entitlements are restricted to paid accounts is as a form of practical security protection. The idea here is that the underlying details of development signing's limitations: Builds only run on the specific devices that were registered when the signing profile was generated. Registering a device requires extracting informat

As of macOS 26.4, WKWebView content disappears after 3 seconds when part of a legacy ScreenSaver view hierarchy.
The title says it all, and I've filed FB FB22353950 that includes an Xcode 26.4 Screen Saver test project, QT movie demonstrating the error, and a PDF with complete steps to build and test. I'm asking here just to learn if this sounds familiar. The SS built on 26.4 fails in 26.4, works fine on 26.3.1. I'll supply the test files if there's interest. Thanks.

@catelinecz May I ask you 2 things if I may. Can you create a new thread and post your code there so can be a separate thread? Can you also create an enhancement request for the universal links team to take a look? If you're not familiar with how to file enhancement requests, take a look at Bug Reporting: How and Why?

Coming back to your throughput issue, let me start with a general comment and then return to the specifics of your case. In general, the on-the-wire behaviour is going to vary based on the performance mode: Realtime Bulk In the realtime mode (WAPerformanceMode.realtime), the behaviour is described by Figure 53-1 and its associated text in the Accessory Design Guidelines for Apple Devices, available from Developer > Accessories. In bulk mode (.bulk) the behaviour is adaptive, with allocations ramping up as there’s more traffic. Regarding your specific case, my understanding is that you’re in conversation with other folks at Apple about your product. I can’t discuss those details here on the forums, because this is a public environment. However, those folks asked me to remind you that the were hoping to get some logs from you. The best way to submit those is via Feedback Assistant. Once your done, post your bug number here and I’ll pass it along. Oh, and I also wanted to remind you about filing an E

WKWebView could not access local javascript files
We are experiencing an issue after Xcode 26.0 to load local javascript files to WKWebView to render our own design. it used to work well, however after Xcode 26.0, when [self.webView loadFileURL:fileURL allowingReadAccessToURL:accessURL]; it returns [PID=1514] WebProcessProxy::hasAssumedReadAccessToURL(3198190): no access self.webRootPath = [[NSHomeDirectory() stringByAppendingPathComponent:@Documents] stringByAppendingPathComponent:CHAT_VIEW_WEB_ROOT]; NSFileManager *fileManager = [NSFileManager defaultManager]; NSError *error = nil; if (! [fileManager fileExistsAtPath:self.webRootPath]){ [fileManager createDirectoryAtPath:self.webRootPath withIntermediateDirectories:NO attributes:nil error:&error]; } NSURL *accessURL = [NSURL fileURLWithPath:self.webRootPath]; Not sure how to assign access permission to WKWebView. Any help much appreciated.

Reply to WKWebView could not access local javascript files
On my end, it was due to call [self.webView loadFileURL:fileURL allowingReadAccessToURL:accessURL]; multiple times, even though it was worked on earlier version. here is the response from Apple side The loadFileURL:allowingReadAccessToURL: call should be made only once, after all the resource files have been copied. The CSS and image files don't need to be loaded individually — they will be loaded automatically by the HTML when it references them, because your accessURL grants WKWebView read access to the entire cv_webroot directory. Here is what the corrected flow should look like: hope this helps.

I am having the same issue. We have multiple domains pointed to a single server. Plain domains are working, IDN domains are not working. Issue seems to be also present in macOS version of swcutil. When trying to download AASA file with it, command fails with error. See attached code block.

How to modify the launchctl config to start Postfix?
On Sequoia, I want to configure my postfix as a server. And for this I have to change the way postfix is started from: /System/Library/LaunchDaemons/com.apple.postfix.master.plist But this file is on the read only / file system. Then I just unloaded this startup, and made a new one in: /Library/LaunchDaemons/com.apple.postfix.master.plist and I was able to start it. But on the next system boot, the system one in /System/Library/LaunchDaemons was started again. How should I cleanly and permanently achieve this server basic modification?

Reply to My macOS app is unable to read a Managed Preferences plist unless the App Sandbox is disabled. Is there any solution to read the MDM plist file while the sandbox is still enabled?
Could you please suggest the recommended approach? In this scenario, the user should not be required to select a file manually (such as through drag-and-drop), since the file must be accessed and read automatically without user interaction. However, I am facing the same issue even when attempting direct access.
