Manually Mount the Metal Toolchain When Xcode Cannot
My Xcode 26.2 still suffers from an inability to compile Metal shader files because it can’t find the Metal toolchain: error: cannot execute tool ‘metal’ due to missing Metal Toolchain; use: xcodebuild -downloadComponent MetalToolchain That command also doesn’t do anything to fix this for me. But I did have success mounting the .dmg file with the toolchain manually.
