I downloaded and installed OS X Mountain Lion last night and everything was working normally. I started working in Photoshop CS4 this morning (the first time after installing ML) and when I try to drag a layer to create a new layer, or when I try to move a layer to another PS document, it shows the beach ball of death and then crashes. It has crashed on other occasions, not just doing these actions. Before installing ML I haven't really ever had a problem with PS crashing. I reinstalled PS earlier today to see if that would help but it still crashes. Any ideas on why this is happening or how I can fix it?


Thanks for any replies, in advance.

    While CS4 is getting a bit old in the tooth now, Adobe says there are no known issues as of the 25th !


    Adobe CS apps & Mountain Lion: No known issues

    BUT that comment thread there is a bit long ->


    If you encounter any issues, please report them on our bug reporting form.




    FAQ: I found a bug. How do I write a useful bug report? Or send bug files to Adobe?

    Do you believe then that Mountain Lion has nothing to do with photoshop crashing constantly?

    Well if anyone was still looking at this looking for answers I have figured out this so far:


    If I go to the system preferences panel>energy saver> and unchecked "Automatic graphics switching", I can now move layers without photoshop crashing.




    If I use the keyboard shortcuts for moving layers instead of moving them with my mouse I can move layers without photoshop crashing.

    yeeeks! i did as teganv said and photoshop no more crash.

    Tegan, how did u discovered the trick?

    Just searching around the internet actually. It wasn't easy to find it, and I wasn't sure it would work but it did. Also, not sure if I put this in my post for an "answer to the problem", (and yes I am too lazy to look). I unticked that box and opened photoshop and worked and the next time I went to open photoshop I ticked the box again to see if it would continue to crash and it didn't so I think it might just be a one time thing and then your good to go.

    I just tried that and it worked. The only thing I had to do was to restart Photoshop. Thank you, you are brilliant.

    Thanks you so much for this response!  I have been talking to Adobe tech support and they simply said they don't support CS4 anymore but would be happy to upgrade me to CS6 at the FULL price!


    Your advice worked and saved me stress and frustration and $$!


    Thanks very much!
