Hey all - I just reinstalled my system on a new system drive and then used the migration assistant to transfer *only* the user accounts and not the settings or applications etc. I wanted (needed...) to start relatively clean. The system after all of this is very similar to the original system (same apps, same users, mostly the same settings etc.) and I would like to continue using my old Time Machine back-up if I can, but when I start Time Machine it just wants to create a new back-up and won't recognize the older back-up. Any thoughts about getting that to work? I've read up about what to do if you get a new TM disk or if your have your logic board replaced, but this situation seems different. I can't figure out what would appear different to TM about my "new" system. Thoughts?
