PS 21.0.0 is profoundly slow on macOS 10.14.6

[markdphoto]

I recently upgraded to the latest version of PS and it is grindingly slow now.

I am on a Late 2012 iMac with 32GB RAM and running OSX 10.14.6. 

I suspect some sort of memory management issue. 

While I have a scratch disk with 350GB available, the preferences note I only have 75GB. Why?

Virtually every command or task invokes a spinning beach ball. Yesterday a save of a 100MB JPG took 5 minutes.

On top of this I get "Out of application memory" and "Your scratch disk is full" warnings.

I have disabled Dropbox and Backblaze and incidental apps and am only running LR (latest version) and PS.

It's something wront with this version. I've bot latest Mackbook Pro and it freezes constantly.

Hi there,

Sorry to hear about the performance issues with the latest version of Photoshop, could you please try deselecting "Use Graphics Processor" located in Photoshop's Preferences > Performance, then relaunch Photoshop and let us know if it helps?

You may also try optimizing the preferences of Photoshop by following the steps mentioned here: https://helpx.adobe.com/photoshop/kb/optimize-photoshop-cc-performance.html

Did that. Seems a bit better but then I got a "Cannot save file because your disk is full" warning.

Not only that, but when I go to look at scratch disks in the prefs, the primary scratch disk does not appear in the list anymore.

I have 350GB free on the disk in question.

Hi Mark, 

What you're seeing is likely due to low disc space on your OS volume, not your scratch disc. How much space do you have free on your OS volume? (where PS is installed and launched from)

Thanks,

Adam
