Actualicé mi OSX a 12.4. después de eso mi brew mysql no arranca.
Lo tengo:
$ brew services start mysql
Bootstrap failed: 5: Input/output error
Try re-running the command as root for richer errors.
Error: Failure while executing; `/bin/launchctl bootstrap gui/501 /Users/gerd/Library/LaunchAgents/homebrew.mxcl.mysql.plist` exited with 5.
Creo que es un problema de permisos. La parada de brew mysql por Root en la actualización a 12.4
brew services list
Name Status User File
mysql stopped root ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
