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?

Hello, when I'm looking to customize the icons of my phone, the applications that are in the grouping genres without replacing with all-black images, I don't know what happens by changing the color of the applications in group of change no color throws just listen not the black stuff

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"

Hello everyone, I'm working on a screen recording app using ScreenCaptureKit and I've hit a strange issue. My app records the screen to an .mp4 file, and everything works perfectly until the .captureMicrophone is false In this case, I get a valid, playable .mp4 file. However, as soon as I try to enable the microphone by setting streamConfig.captureMicrophone = true, the recording seems to work, but the final .mp4 file is corrupted and cannot be played by QuickTime or any other player. This happens whether capturesAudio (app audio) is on or off. I've already added the "Privacy - Microphone Usage Description" (NSMicrophoneUsageDescription) to my Info.plist, so I don't think it's a permissions problem. I have my logic split into a ScreenRecorder class that manages state and a CaptureEngine that handles the SCStream. Here is how I'm configuring my SCStream: ScreenRecorder.swift // This is my main SCStreamConfiguration private var streamConfiguration: SCStreamConfiguration { var streamConfig = SCStreamConfiguration() // ... other HDR/preset config ... // These are the problem properties streamConfig.capturesAudio = isAudioCaptureEnabled streamConfig.captureMicrophone = isMicCaptureEnabled // breaks it if true streamConfig.excludesCurrentProcessAudio = false streamConfig.showsCursor = false if let region = selectedRegion, let display = currentDisplay { // My region/frame logic (works fine) let regionWidth = Int(region.frame.width) let regionHeight = Int(region.frame.height) streamConfig.width = regionWidth * scaleFactor streamConfig.height = regionHeight * scaleFactor // ... (sourceRect logic) ... } streamConfig.pixelFormat = kCVPixelFormatType_32BGRA streamConfig.colorSpaceName = CGColorSpace.sRGB streamConfig.minimumFrameInterval = CMTime(value: 1, timescale: 60) return streamConfig } And here is how I'm setting up the SCRecordingOutput that writes the file: ScreenRecorder.swift private func initRecordingOutput(for region: ScreenPickerManager.SelectedRegion) throws { let screeRecordingOutputURL = try RecordingWorkspace.createScreenRecordingVideoFile( in: workspaceURL, sessionIndex: sessionIndex ) let recordingConfiguration = SCRecordingOutputConfiguration() recordingConfiguration.outputURL = screeRecordingOutputURL recordingConfiguration.outputFileType = .mp4 recordingConfiguration.videoCodecType = .hevc let recordingOutput = SCRecordingOutput(configuration: recordingConfiguration, delegate: self) self.recordingOutput = recordingOutput } Finally, my CaptureEngine adds these to the SCStream: CaptureEngine.swift class CaptureEngine: NSObject, @unchecked Sendable { private(set) var stream: SCStream? private var streamOutput: CaptureEngineStreamOutput? // ... (dispatch queues) ... func startCapture(configuration: SCStreamConfiguration, filter: SCContentFilter, recordingOutput: SCRecordingOutput) async throws { let streamOutput = CaptureEngineStreamOutput() self.streamOutput = streamOutput do { stream = SCStream(filter: filter, configuration: configuration, delegate: streamOutput) // Add outputs for raw buffers (not used for file recording) try stream?.addStreamOutput(streamOutput, type: .screen, sampleHandlerQueue: videoSampleBufferQueue) try stream?.addStreamOutput(streamOutput, type: .audio, sampleHandlerQueue: audioSampleBufferQueue) try stream?.addStreamOutput(streamOutput, type: .microphone, sampleHandlerQueue: micSampleBufferQueue) // Add the file recording output try stream?.addRecordingOutput(recordingOutput) try await stream?.startCapture() } catch { logger.error("Failed to start capture: \(error.localizedDescription)") throw error } } // ... (stopCapture, etc.) ... } When I had the .captureMicrophone value to be false, I get a perfect .mp4 video playable everywhere, however, when its true, I am getting corrupted video which doesn't play at all :-

Since macOS 15.3.2, we have observed that when another window is moved near the App Store's install button, the button disappears. We have attached a related video in the Feedback submission here https://feedbackassistant.apple.com/feedback/20444423 Our application overlays a transparent, watermark-window on top of the system window, which causes the install button in the App Store to be hidden when a user attempts to install an application.Could you advise on how to avoid this issue?

I have a game built in Unreal Engine 5.6 which uses tilt motion controls to rotate an object. I've restricted the app to only run in portrait for iPhone, and everything works fine, however for iPad I've had a few issues relating to multitasking and I can't seem to solve it. Forcing the app to portrait only still allows the app to run in landscape mode, but shows black bars either side of the game, and the axes for the motion controls are incorrect. X becomes Y and Y becomes X, and there's no way for my app to know which orientation it is because the container is still technically portrait. Allowing my game to run in all orientations makes the whole app more presentable, it doesn't add black bars and the game is still functional and I'm able to map the controls correctly because the game knows it's landscape rather than portrait. The problem with allowing my app to run in landscape mode is if multitasking is enabled on the ipad, you can resize the app to be portrait, and then I run into the same problem again where the game thinks it's portrait mode and all of the axes are wrong again. I tried getting the true orientation of the device rather than the scene, but the game is intended to be played flat so instead of returning the orientation of the OS the orientation is FaceUp, which doesn't help. I need to either disable multitasking or find a way of getting the orientation of the OS (not the scene or the device). I haven't found how to get the OS orientation so I've been trying to disable multitasking. I've got Requires Fullscreen true and UIApplicationSupportsMultipleScreens false in my info.plist but my iPad still seems to allow the window to be resized in landscape view. Opening the IOS workspace of my project Requires Fullscreen is ticked but under that it says "Supports Multiple Windows" and the arrow button next to it takes my to my info.plist values, but no indication of how I can change it. I'm using Unreal Engine 5.6 and Xcode 16.0. Xcode is old I know, but this version of unreal engine doesn't seem to support any newer.
