Is it possible to use Unreal Engine 5 on an old Mac?

If selecting the version the way I indicated didn’t help out, another user had to fully reinstall before it worked out:

Unreal 5.2 wont launch (Xcode not found)

I have a Mac Studio with the M2 and it works fine. However, when updated, did you uninstall And delete everything from the Shared folder and reinstall Unreal? UE 5.2 added support for  Silicon. So if you have binaries left over from <5.2 it’s possible that would cause the problems, that some binaries are for ARM and others for Intel. I would do a very clean install of Unreal now that you have updated your OS and Xcode.
