I am a complete OS newbie. My TM stopped making successful back ups to my TC on the 7th. Concurrently my Finder has been 'Not Responding' and generally locking up programs and tasks. I have tried a few suggestions from a previous thread (clearing cache, checking rights, uninstalling pathfinder, etc), but despite the very patient and generous support, none of it has resolved the problems. So I have decided to do a TM roll back to prior to the problems. I assume my reminders, notes and contacts will be updated from the Cloud (right?). To restore the documents I have edited since the 7th, should I copy my documents folder to my external drive? To keep my Outlook emails, I assume I should do a pst export to my external drive... right Any advice or suggestions? How hard is a roll back like this to do?
