This is driving me crazy!! Every so often, Photoshop will just stop responding. I can't do another action, can't click on layers, and I can't even save my projects. It dosen't matter what size the project is as I have this problem with big and small projects. I can't seem to find a pattern to what is causing it. Like yesterday, it was running smoothly for a couple hours and then just stops working. Today I can't even get five minutes in. The mouse is fine. The program won't respond is my problem.
Version: CS6 v 13 x64
Computer: Macbook Pro (13-inch, 2017, Two Thunderbolt 3 ports) High Sierra 10.13.1
I am having this issue as well and it just started today. I tried our iMac first and then our MacBook Pro 15. I have an older version of PS CS6 Extended not the current subscription. I am assuming that updates will not be available.
No updates - CS6 is "End of life".
