This has been plaguing me for a while since I updated to Mac OS 10.8. Dragging layers in the layers palette of Photoshop CS4 would cause an immediate crash to desktop. Finally found a solution in this thread which worked.
Solution: turn off the OS power-saving graphics switching.
It's the checkbox at the top of the Energy Saving preference pane:
You'll need to ensure that it's unchecked and probably restart after that.
Now I can drag layers all day long.
Thank you so much!
At last a short, clear and efficient answer!
Glad it helped you out!
this little trick worked for me. wish i seen it before deleting and reinstalling everything to no avail. thanks for posting it.
No problem at all.
thanks for posting; you saved me :-)
Excellent :)
Finally, relief after SO MANY HOURS of tearing out my hair - thank you for posting this!!!
You're very welcome, glad it helped you out.
I need to search this topic once a year when I upgrade my OS. Yours came up first this time. Thanks! I believe there's a second symptom and fix for this problem. A dynamically switching video card may also make PS unstable. I have to remember to set my card to Discrete Only with the gfxCardStatus app as well. Maybe there's a more permanent workaround that I'm not aware of.
Glad it helped you out. I'm going to check out that app you mentioned, too.
Thank you for this post! It works!!!!
Great, I'm glad to hear it!
OMG THANK YOU!! I assumed this couldn't be fixed, then finally TODAY I thought I'd google to see if there were solutions! I can't believe it was this simple! Problem solved!! THANK YOU!
- And thank you for titling this perfectly so it was easy to find in a google search!
*salutes*
*salutes back!*
- I've been dragging layers and folders around all day :)
Thank you again!
Quick, efficient fix - thank you!!!
You're welcome, glad I could help!
Had this problem again, and I knew there was a solution I'd found online before, but couldn't remember what it was. Googled and found your post. Looks like this is where I found the solution a few years ago too, because I see my previous comments to you! Thank you again!
Haha, glad to be of service! :)
