I have this issue, while I am using Photoshop/Illustrator suddenly my Macbook Pro freezes, I can't click, move, close, force quit or anything. Only way is to turn off macbook and start it again. I think, it started, when I updated to 2017 version.
I have CC version of both application. (2017) And my macbook is: early 2015, macbook pro retina, 8gb RAM.
I tried already to scan if there is some virus or malware - antivirus found nothing.
Thanks for help!
Please ensure that Photoshop and Illustrator are both updated. Did you check reproducing the issue with only one of these applications are running at a time? This could be related to lack of memory or space on your computer.
Post the Photoshop>Help>System info if you're able to get there.
