Far from fixing things, it appears that Apple have messed up terminal. I have tried this on all Three of my Macs after the update, and they all give the file system error: [ERROR] <CPPathUtils.c:526> The device-file for this operating system, 'osx-12.1.0.xml', was not found. An attempt to revert to a previous revision of the OS device-file: 'osx-12.0.0.xml' has been made. Please file a Radar report with Apple, on the 'CoreProfile' component, version 'X'. I wil send a report to them, anybody else having issues with terminal post update?
