I repeatedly need to reinstall Mac OS
Over the past year, and on two successive MacBook Pros, periodically the log-in password becomes invalid (not recognized during log-in) and the only solution is to re-install the Mac OS and all my files. This is only happening on my MacBook Pro, not on my wife's MBP or my iMac. Any idea how to figure out the problem?
MacBook Pro 16″, macOS 12.3
