Hi All,

I'm having a recurring problem that is causing a major headache and I would be very grateful for any advice.

For your reference, details of my system below

Media Composer 2021.6.0

OS X 11.4

2.9ghz 6-Core

32GB DDR4 RAM

Radeon Pro 560x 4GB

(My preference woud have been not to upgrade to Big Sur but unfortunately this system came pre-loaded with it. So downgrading to a previous version of OSX is possible but a bit of a fraught process. Would rather avoid if possible.)

In general I'm getting great performance inside Avid, everything works great and have had no problems inside the software. 

The major issue I'm coming up against happens if tabbing between other software, and then going back into Avid. For example, going into Safari for a few minutes and then returning to the Media Composer window. On doing so, generally the system will hang for far longer than is normal with the spinning beach ball waiting for Avid to "wake up". Sometimes after a long wait the software will function. On other occasions, it will cause Avid to crash making a "force quit" required. And I have just had an experience where the crash caused by going back into Avid was so bad the whole system locked and I had to force a restart.

The strange this is, the problem doesn't happen every time - it appears to be random. But when it occurs, it's a serious issue and needs resolving. I have even tried using another browser alternative to Safari but to no avail. 

I saw on another thread someone discussed changing the Video Memory settings in the Media Cache window. I took a look and saw that by default this was at the "low" level of 2GB. I then tried setting it to what is advised as being "high" (in my case 22GB). After this change is when I eventually got the problem that tabbing back into Avid caused the whole system to freeze entirely so I have now set it a lower allocation of 10GB.

Does anyone have any advice on this? I am happy to downgrade to an earlier version of Media Composer if this is a known issue with the latest version I am currently running. As discussed above, downgrading to an earlier version of OS X is a little more difficult.

In short - help!
