Hello I am having the same problems as the above user. My computer meets all the needed requirements to run photoshop this current verison of Photoshop. I have the latest upodate of OS system, as of yesterday actually. I only purchased this Mac Book Pro two months ago after using my last Mac Pro for 9 years without an issue. During that time I have never had an issue with any Adobe products. The past week while editing some recent work I noticed a slight lag from my cursor while using the masking tool in Camera RAW and also in Lightroom. That lag became longer and with more of a delay more and more difficult to get my work done. It culminated over the past two days with mulitple crashes and forced quits. I spent 4 hours yesterday with multiple Apple tele help employees trying various things. Unistall and install the third party Apps that were causing this crash, trying to use the Ap is safe boot mode, and last but not least Reinstalling the latest OS system. All of which took much of the day, and by the end of it, Apple concluded that this is an Adobe problem. I have tried everything suggested in the below (above?) thread. In both my programs, I have deleted preferences, I have unclicked the Graphics Processor with each new "fix" I have turned off and tried to reboot to no avial. I too am at my witts end to be honest as my deadline has now passed and I still cannot do what I need to do in either Lightroom or Photoshop.
Adobe if you are listening, what is going on here? Is there anyone else out there having similar problems still?
Thank you in advance!
