Sorry, wrong path: MetalToolchain-17A5241c.exportedBundle => MetalToolchain-17A5241l.exportedBundle xcodebuild -downloadComponent metalToolchain -exportPath /tmp/MyMetalExport/ sed -i '' -e 's/17A5241l/17A5241n/g' /tmp/MyMetalExport/MetalToolchain-17A5241l.exportedBundle/ExportMetadata.plist xcodebuild -importComponent metalToolchain -importPath /tmp/MyMetalExport/MetalToolchain-17A5241l.exportedBundle

It no longer works for me under Xcode 26 beta 2, so I need to change the version number. change like this： xcodebuild -downloadComponent metalToolchain -exportPath /tmp/MyMetalExport/ sed -i '' -e 's/17A5241l/17A5241n/g' /tmp/MyMetalExport/MetalToolchain-17A5241c.exportedBundle/ExportMetadata.plist xcodebuild -importComponent metalToolchain -importPath /tmp/MyMetalExport/MetalToolchain-17A5241c.exportedBundle then reboot your mac right now.
