Why did you upgrade/what problem are you trying to solve?

>>> None, other than the fact my system is old, browsers aren't supported, I can't run any of the Line6 Helix software, etc...

A core 2 Duo may be underpowered for your needs... it’s certainly under-minimum spec for any modern version of Pro Tools.

>>> Perhaps you are correct. Seems to work fine at Lion and PT10, no issues through the years.

4GB really is not enough to run Pro Tools 111/12 or later.

>>> I agree 100%. Other World Computing states an old mid-2007 iMac can be upgraded from 4GiB to 6GiB of RAM with a (4+2) pack. I had intended on upgrading the RAM if all played nicely. Few years back I put in a 480GiB SSD drive and that works very well.

What Exact Pro Tools license do you have. You can purchase perpetual upgrades that get you 10/11/current releases tgat will also run 12, and if you have a license for 12 and ask nicely Avid will deposit 12 downloads in your aaccount if they are not out there automatically.

>>> I started on PT 7, and did upgrades from there. I purchased an upgrade for PT 9, which then got me to PT 10. That's it, I have no more licenses.

Rolling back to a backup may be the best option.

>>>> I did, thank goodness for Time Machine and my WD MyCloud! :) Everything is back working again on Lion & PT 10.
