Hi everyone,
I downloaded Xcode 27.0 today because I need the Metal Toolchain for Unreal Engine 5.6 on my Mac.
Xcode itself is installed and working, but Unreal is having issues because the Metal Toolchain doesn't seem to be installed.
When I run:
xcrun metal --version
I get:
error: error: cannot execute tool 'metal' due to missing Metal Toolchain; use: xcodebuild -downloadComponent MetalToolchain
I tried:
sudo xcodebuild -downloadComponent MetalToolchain
but it just stays on:
Beginning asset download...
If I cancel it, I get:
xcodebuild: error: Download was cancelled. (Asset download for com.apple.MobileAsset.MetalToolchain ...)
I've also run:
xcodebuild -runFirstLaunch
and installed the latest Command Line Tools for Xcode 27.0 through Software Update.
xcrun --find metal does find the executable, but the actual Metal Toolchain appears to be missing.
I'm mainly trying to get this working so I can use Unreal Engine 5.6.
Has anyone had this issue with Xcode 27, or know the correct way to install the Metal Toolchain when xcodebuild -downloadComponent gets stuck at "Beginning asset download"?
Thanks!
