I came in to put some time into my project and have been fighting PT for over an hour to get it to stop with the CPU overloads, freezing, crashing, driving me crazy. I finally copied my session file just to see what would happen if I deleted everything except the 9 audio tracks currently being worked on—totally stripped down to those 9 tracks—and it still does it.

Have done an SMC reset.
Have restarted several times.
Ejected all but my Pro Tools external drive.
Not a single other program running.
iMac (Retina 5K, 27-inch, Late 2015)
4 GHz Intel Core i7
32 GB 1867 MHz DDR3

When idle, my CPU usage shows in the red as shown in the attached screen shot. As soon as I arm any track to record, it overloads and freezes.

Any ideas on what I can do with this?

Thanks.
