Hey guys, I am starting to learn game development on Unreal Engine. And I have been facing conflicts between Unreal Engine version and XCode. **Error Description :** Setting up bundled DotNet SDK /Users/Shared/Epic Games/UE\_5.6/Engine/Build/BatchFiles/Mac/../../../Binaries/ThirdParty/DotNet/8.0.300/mac-arm64 Running dotnet Engine/Binaries/DotNET/UnrealBuildTool/UnrealBuildTool.dll Development Mac -Project=/Users/Me/Desktop/UnrealProjects/MyProject/MyProject.uproject -TargetType=Editor -Progress -NoEngineChanges -NoHotReloadFromIDE Log file: /Users/Me/Library/Application Support/Epic/UnrealBuildTool/Log.txt Creating makefile for MyProjectEditor (no existing makefile) Platform Mac is not a valid platform to build. Check that the SDK is installed properly and that you have the necessary platform support files (DataDrivenPlatformInfo.ini, SDK.json, etc). Result: Failed (OtherCompilationError) Total execution time: 1.33 seconds **Unreal version:** 5.6.1 **XCode version:** 26 I tried downgrading my XCode version to 15.4 to make it work with UnrealEngine, but Macbook forces me to upgrade the XCode version. Any help would be greatly appreciated ---

I just run into an issue today after upgrading to Xcode 26. Could be different with UE 5.6 but this worked with 5.5: Edit the file `/Users/Shared/Epic Games/UE_5.5/Engine/Config/Apple/Apple_SDK.json` and change the line for MaxVersion to “MaxVersion”: “26.0.0”. In case you later get an error related to Xcode Metal compiler go to Xcode → Settings → Components, look for Metal toolchain and click download. ---

Check compatibility, update Xcode, and clear derived data to fix Unreal Engine Mac Conflicts. ---

Solution didn’t work for me because i ended up being on a later version of xcode already.To check your version you can run this command and then update the max version accordingly `plutil -extract CFBundleShortVersionString raw /Application/Xcode.app/Contents/Info.plist` Hope it helps! ---

Thank you! I had the same issue and had to go to Xcode Settings =\> Components and at the bottom I had to install the Metal Toolchain 26.0.1 … after doing that UE launches! ---

Be careful if you just update the max version! : ``` “NOTE: If you update the MaxVersion, double check the AppleVersionToLLVMVersion array below!!!” ``` I suspect there are no major changes in the LLVM version, and that’s the only reason it works. But be careful, you might run into issues or other compile erro
