Hi

Nope.  Removing the file does not help.

marcoxa$ rm ~/Library/Colors/Emacs.clr

marcoxa$ emacs &
[1] 33269
Bougaza:magiciel marcoxa$ 2024-05-09 11:22:44.978 Emacs-x86_64-10_14[33269:5028483] Failed to initialize color list unarchiver: Error Domain=NSCocoaErrorDomain Code=4864 "*** -[NSKeyedUnarchiver _initForReadingFromData:error:throwLegacyExceptions:]: non-keyed archive cannot be decoded by NSKeyedUnarchiver" UserInfo={NSDebugDescription=*** -[NSKeyedUnarchiver _initForReadingFromData:error:throwLegacyExceptions:]: non-keyed archive cannot be decoded by NSKeyedUnarchiver}

The file gets regenerated, but so does the error.

All the best

When this came up before (e.g., bug#32854), our macOS expert said the
reason was a stale or corrupt version of the color file, and the
solution was to delete it:

  rm ~/Library/Colors/Emacs.clr

Can you try this and see if it solves your problem?
