Dear Apple Color Management Team, I’m a professional visual creator working on color-critical photo and graphic projects using macOS (currently 26.1 Tahoe). In recent macOS releases, LUT-based ICC display profiles (such as XYZ LUT + Matrix types generated by DisplayCAL or professional spectrophotometers) can no longer be installed or activated via ColorSync. This limitation significantly affects professional workflows in photography, graphic design, prepress, and video color grading — fields that rely on precise display profiling. The current workaround (converting LUT profiles to simple shaper/matrix ICC v2) results in less accurate tone response and color reproduction, particularly in the dark range and wide-gamut displays. I kindly request Apple to restore or re-enable the ability to install and use ICC v2/v4 LUT-based display profiles under ColorSync, as was possible on macOS Monterey and Ventura. This would allow professionals to continue using trusted calibration tools such as DisplayCAL, X-Rite i1Profiler, and Calibrite Profiler to achieve accurate color management. macOS is widely used in professional creative industries, and restoring this feature would be a huge help for countless photographers, designers, and colorists. Thank you for your attention and commitment to professional users. Best regards, Richárd Deutsch Professional Photographer https://riccio.hu/ MacBook Pro (M4 Pro, macOS 26.1)

Just found out this key available for visionOS https://developer.apple.com/documentation/bundleresources/entitlements/com.apple.developer.low-latency-streaming It seems to keep video streaming from being interrupted by AWDL, our community needs it badly for self-hosted game streaming (PC to iPhone / iPad). Related apps: Moonlight / VoidLink / SteamLink. Can we expect this on iOS/iPadOS 26, or even iOS/iPadOS 18 ?

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.

How can I paste a string to the findNavigator of a TextEditor ?

I have been trying to run an open source Windows executable that I would like to help porting to macOS using the Game Porting Toolkit but I stumbled on an issue quite early in the application lifecycle. It looks like the funtion GetThreadDpiHostingBehavior is missing in USER32.dll Has anyone any idea how to solve that? During the startup, it fails with the following error: TiXL crashed. We're really sorry. The last backup was saved Unknown time to... C:\users\crossover\AppData\Roaming\TiXL\Backup Please refer to Help > Using Backups on what to do next.

I think I really have tried everything and I did all according to official documentation to support game mode on iOS or iPadOS but it doesn't matter what I do it just doesn't get triggered. Funny enough it works during development when I install it via Xcode but as soon as it is live on the store and when I install it from there game mode doesn't get triggered anymore. What I have atm I have added (even though it is deprecated) <key>GCSupportsGameMode</key> <true/> I have set the (but it seems only supported for macOS) <key>LSApplicationCategoryType</key> <string>public.app-category.games</string> I have added <key>LSSupportsGameMode</key> <true/> It just doesn't work. Is there anything else what needs to be done? Should the flag LSSupportsGameMode not be enough normally? The reason why this is so annoying is that my app is a real time streaming app and I want to profit from minimised background activities for smoother gameplay and more consistent frame rates like mentioned in the documentation.

We used below method to resize image while compress the image, Below method is correct or need to do the correction in method or "CGBitmapContextCreate" -(UIImage *)resizeImage:(UIImage *)anImage width:(int)width height:(int)height { CGImageRef imageRef = [anImage CGImage]; CGImageAlphaInfo alphaInfo = CGImageGetAlphaInfo(imageRef); if (alphaInfo == kCGImageAlphaNone) alphaInfo = kCGImageAlphaNoneSkipLast; CGContextRef bitmap = CGBitmapContextCreate(NULL, width, height, CGImageGetBitsPerComponent(imageRef), 4 * width, CGImageGetColorSpace(imageRef), alphaInfo); CGContextDrawImage(bitmap, CGRectMake(0, 0, width, height), imageRef); CGImageRef ref = CGBitmapContextCreateImage(bitmap); UIImage *result = [UIImage imageWithCGImage:ref]; CGContextRelease(bitmap); CGImageRelease(ref); return result; }

Turn-based games: 2 players When an opponent declines a game in the Game Center MatchMaker VC, that player sees that they quit, but no message is sent to the listener about that fact. For the person who started the match, their MMVC shows it's their turn again. Why doesn't Game Center end the match?

Was wondering if anyone from Apple could provide some clarification, The gaming studio "Epic Games" Is wondering if they could distribute the award winning game "Fortnite" back on MacOS without any retaliations. I know Fortnite being back on MacOS would benefit thousands of MacOS Devs. Hoping to get a clarification so Epic could start on bringing Fortnite back.

I was wondering if there's a method on MacOS to have my application hide a hid device such as a game controller and instead have the receiving game/application see my app's virtual controller? Is this possible via DriverKit or some other form of kernel level coding? On Windows we have a tool known as HidHide that hids a game controller from all other applications. Is it possible to implement such behavior into an app or is that system level?
