I’m not a Mac user, but my suggestion should to apply to any OS: why not back up your personal data, wipe the drive and reinstall the OS? Then reinstall the applications and your data.
Inconvenient? Sure, but cheaper than buying a new computer.
Yes, that would be one way to solve the problem but very, very inconvenient. Unfortunately, that computer is in my Washington office and I can only access it remotely. I won’t be back up there until this summer.
Thanks for the suggestion though. Something to keep in mind if I don’t break down and buy one.
FWIW When I do play round robin with the machines up there, I always buy pre-owned.
