So I read a question posted earlier about installing Unreal Engine on the boot drive of your Mac and then moving it to an external hard drive for use there, but I was having difficulties getting the symbolic link to work.
So, I followed these instructions, but then when I try to boot up Unreal from my external hard drive, when I open Epic Games, the button for “Launch” is replaced with “Repair”. When I click on it, it attempts to reinstall Unreal on the boot drive of my Mac, which is not what I want. Any idea of how to fix this?
Looking over what you’ve got here, it looks like the system link wasn’t established in the command you issued. Can you try the combination of terminal commands below (or, if you still have everything where you want on the My Passport, just the second line? You may need to modify it to suit your directories)
sudo mv /Users/Shared/UnrealEngine /Volumes/My\ Passport\ for\ Mac
You can alter the directories to be wherever you would like or wherever you currently have your data stored, but it’s important for the link actually be established to the UnrealEngine folder location; the Launcher reads from that folder, so any changes to the path aren’t going to have the result you want. This also holds for system/symbolic links; if the Launcher can’t find the content it’s looking for in the folder it’s being told is UnrealEngine, then it’s going to assume that you simply don’t have it, and attempt to download that content again to the proper location. Please let us know whether this works out for you!

“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
