Unreal Engine on External Hard Drive (Mac)

if you have UnrealEngine in an external drive, and you tried

sudo xcode-select -s /Volumes/Ext SSD/Applications/Xcode.app/Contents/Developer/

and still getting this Message :
“Can’t find Xcode install for Metal compiler. Please install Xcode and run Xcode.app to accept license or ensure active developer directory is set to current Xcode installation using xcode-select.”

then try this

  • Open Xcode which is in your external Drive
  • Go to Preferences
  • Go to Locations on your bar tab
  • in Command Line Tools, choose the version of your command line

then run Unreal Engine , it will work. it works in my case
