Great point Darryl, I might need that version down the road. Info you requested: Mid 2012 Mac Pro, 3.46 GHz, 6 core Intel Zeon; 8 GB memory 1333MHz DDR3 (two open slots for additional 8 GB); OSX 10.8.5; SSD Sata. The latest version of PT Ultimate that I was trying to update to is 2019.12. The version of PT Ultimate I purchased is the Perpetual license. If I understand your comments, I could just get an updated SSD for one of the other disk spots and do a fresh install of Mojave and then do a fresh install of PT 2019.12 and have the computer boot to the new SSD. Can you recommend a particular SSD drive and are there any other upgrades to the computer you would recommend ? Thanks ! Steve.
