AttributeError: module 'configparser' has no attribute 'SafeConfigParser'

Start in mackup/config.py at _setup_parser, where the traceback shows the failure while constructing the parser. Reproduce the issue with Python 3.13 by running mackup list, then verify the compatibility change by confirming that the command starts without the AttributeError and produces its normal listing.

$ mackup list
