Thanks. I had lots of issues and ended up having to do a clean install (then migrate). Tedious but worked.I upgraded to Sierra couple of weeks ago with no issues except Sound (fixed with Toleda pkg).
Sound somehow resolved itself )).Only sound and booting without the USB drive remaining as issues (at least that I've discovered so far). Low priority, will get to them.
A Time Machine backup requires a fresh installation to move all your data/settings across to.So I always have had this question in the back of my mind, but I don't really know how to properly phrase it in a search engine, so (if it's okay) I'll ask it here:
If I want to upgrade my system, I usually create a backup with Time Machine. In order to revert the system to that backup, I use a Unibeast drive as a recovery USB. However, my question is this: Do I need to have a Unibeast drive from exactly the same version of OS X as that to which I am trying to restore? Or does the Time Machine restoration work by copying the Time Machine backup directly to the computer's drive, so no OS X installation is necessary (thus I can use any Unibeast drive, even from the newest version of OS X)?
