Hi. I am so frustrated and ready to give up on Adobe I have used LR and PS together to edit my photos for more than a decade. For years I used my 2011 iMac and it was wonderful. That iMac died last summer and I bought a 2017 model of the same computer. I downloaded the latest versions of LR and PS and installed them (I had not updated these programs on my old iMac in over a year). I cannot use the latest versions on this new computer for more than about 8 image edits before the lag is so bad I have to force quit and reopen PS.
My workflow is this: Apply LR edits and choose 4 or 5 photos to take into PS. I run a blank layer to clone out problems. Then i usually run a series of self made actions to brighten etc. Then I flatten and close. This works for the first set of photos. Then I go back into LR, select my next 4 or 5 photos and take them into PS. Here is when the issues begin. The clone/heal tool starts to lag and often freezes. I have found if I click on the layer panel about 30 seconds after it freezes, it will unfreeze. By the 4th picture in the group there is a several second delay and I can't heal well because I can't see what I am doing while I am trying to do it. Now when I try to flatten all images it takes a very long time. When I try to run actions on all my images it is painfully slow. It is all I can do to get though those 4 images. Saving takes well over 15 seconds per image. At this point I try to close PS. It more often than not won't close and I have to choose Force Quit. I reopen it and start the whole 8 images process again. Sigh.

I have not configured the RAM up to 16 GB yet because my last iMac only had 8 GB and it was fine. The iMac came with High Sierra installed as the OS.
I am using the most recent version of LR and PS. I don't have any other significant programs on my computer. I'd love to subscribe to all of the Adobe programs but I can only imagine the problems I would have.
Any and all help or guidance would be appreciated. Thank you.
