I have the latest 17inch macbook pro - and just installed mountain lion. And now my photoshop CS6 is hanging. I cannot work at all. Everytime I select a tool - the beachball shows up and hangs for 5-10 seconds. Everytime a make any action it hangs for 5-10 seconds.
I ran a font check in font book and I have no corrupt fonts.
Are Photoshop and OS fully updated?
As with all unexplainable Photoshop-problems you might try trashing the prefs (after making sure all customized presets like Actions, Patterns, Brushes etc. have been saved and making a note of the Preferences you’ve changed) by keeping command-alt-shift pressed on starting the program or starting from a new user-account.
System Maintenance (repairing permissions, purging PRAM, running cron-scripts, cleaning caches, etc.) might also be beneficial, Onyx has been recommended for such tasks.
Weeding out bad fonts never seems to be a bad idea, either. (Validate your fonts in Font Book and remove the bad ones.)
If 3rd party plug-ins are installed try disabling them to verify if one of those may be responsible for the problem.
i tried turning it off.
i have noticed that if i give the system about half an hour rest and then come back to the file im working in it starts running smoothly. I just restarted photoshop with resetting system prefs and it is still hanging.
…I ran a font check in font book and I have no corrupt fonts…
That's meaningless. FontAgent Pro (FAP) is pretty good at ferreting out problem fonts, including those that Font Book and Font Doctor frequently miss. They have a 30-day fully functional trial version on their site.
Get Hardware Monitor or Temperature Monitor to see what the internal temperatures are inside your laptop. That will tell you if it's heat related.
I have a feeling it could be heat related - as i hear the fan working harder - and then when it eventually calms down - photoshop stops hanging.
im clueless when it comes to systems - but i will try your advice.
I had problems with an instalation PS on ML also. Absolutly nothing to help me... In the end i removed Photoshop. (PS was still in menu like "installed" i had to downlowd image from server) and made new installation. Now it is ok, but i had problem with fonts ... I think: there are lots of bugs on Apple site. They make changes, from Mac OS X to iOS, and all they havent interest about professionals ...Thats way why i looking for Font manaher - fontbook is for iSheeps
