I have been having chronic problem with Photoshop since I got a new computer and upgraded to the latest software a year ago. Just so everyone knows I'm running an i7 4.2 GHz quad-core with 24gb of RAM and a Radeon Pro 580 8gb graphics card. My issue is a lag on the menus especially if after I go to the PATHS tab and right click to "Load Selection". The computer gets stuck for several moments. Then over time it's more frequent and affects other menus. I have spoken to Apple support and Adobe support over a dozen times. Apple just replaced my 3TB Fusion drive for a 2TB SSD. I reformatted the drive and started fresh no difference. Does anyone else have this problem? I've been thru every performance combination with Adobe support over the past 12 months and they are now blaming the processor. I had the whole computer tested last week and it came back as working fine. Now hopefully Apple will replace the machine because I can't think of anything else. Please help if anyone has this problem. I make my living photographing hotels and retouching and it's just become so frustrating at times. Worked great for a day after the SSD was installed now back to same old BS.
