Comment (by easye):

 Unfortunately I don't have access to a macOS 15.1 machine to test the
 build of SBCL nor do I anticipate this changing in the near future as
 there are very real concerns about upgrading my aging equipment.

 Therefore I can do very little to resolve your problems other than
 shepherd plausible patches from others.
