Default Overall slow performance after PT 2020.5 and OS 10.15 update


I've been a PT user for the last 10 years. I've gone through every major version since PT 9.

I updated to PT 2020.5 and OS 10.15 about a month ago. Two separate computers exhibit performance issues that were either a) not present or b) not as bad in PT 12.8.

Computer #1 = iMac 2013, 27 inch, Late 2013, 3.4 GHz CPU, 16 GB RAM

Computer #2 = MacBook Pro 2013, 13 inch, Late 2013, 2.5 GHz CPU, 8 GB RAM

Computer #1 was last on OS 10.12 Sierra and Computer #2 was last on OS 10.14, both running PT 12.8.

After upgrading to PT 2020.5 and OS 10.15, I get:

- Constant CPU overload errors when using half of the plugins I used to use

- Distorted audio after CPU overload, resulting in me having to toggle buffer size to reload audio system

- Project load times multiplied significantly

- Plugin load times multiplied significantly

- Antares AutoTune EFX crashes PT upon first load. Works fine afterwards.

Disclaimer: I'm fully aware that OS 10.15 is notoriously slower than other recent Mac operating systems. However, I'm getting the same exact behavior in PT 2020.5 on multiple machines.

If anyone has similar experiences or can shed any insight, I'm all ears.
