Photoshop 2020 (version 21.1.3) using 100% CPU on iMac running macOS 10.14.6

[mlofoto102309]

I am using CC 21.1.3 on iMac with running OS 10.14.6 w/64GB Ram. CC is constantly using 100% or more(!!) of CPU which delays all tool usage. I had this problem occasionally with CC before the current update but was able to fix by closing the program and rebooting the computer. Now, that doesn't help. I have LOTS of scratch disk room, I have closed all other programs except Activity Monitor. 

Any help appreciated.

Hi Michael,

We're sorry about the trouble due to the high CPU usage while working in Photoshop. Would you mind trying to optimize the performance of Photoshop using the steps mentioned in the article: https://helpx.adobe.com/photoshop/kb/optimize-photoshop-cc-performance.html

You can try to reset the preferences of Photoshop using the steps mentioned here: https://adobe.ly/2Qzc0K3

Please backup your settings prior to resetting the preferences. You can check: https://adobe.ly/2vNz6FG

Let us know how it goes!
