Photoshop CC 2015 on iMac with MacOS 10.11 El Capitan is still very slow and laggy.

I'm running OS X El Capitan 10.11.1 and Photoshop CC 2015.1.1. Photoshop's performance is still very slow and the interface is very laggy, to the point of being counter-productive (for example, trying to type a number into a Gaussian Blur window and having to wait 7 seconds until my typing actually takes effect).

I'm working on relatively small files in the 50 MB range that contain several layers. Performance was fine in Photoshop CC 2014 in Mavericks.

I'm using a 21.5 inch iMac, 10.11.1, 2.9 GHz i5, 16 GB RAM, Nvidia GeForce GT 750M (1 GB running a secondary monitor), and 1.1 TB Fusion drive.

Any suggestions, or do I have to be patient and hope the next update puts Photoshop back to normal?

(Photoshop CC 2014 ran fine on Mavericks, but runs very poorly on El Capitan just like Photoshop CC 2015. I was hoping the latest update would solve this, but it didn't.)

I realized there's an OS X update, which I just installed (10.11.2) and now Photoshop CC 2015 seems to be working better. It's much more responsive now.

I apologize for that oversight.

I'll continue to monitor Photoshop's performance and will reply again if problems come back.

I think I've found the solution guys. I was having the same issue on my macbook pro. My solution was to uninstall Photoshop through the creative cloud icon that appears in the top bar of my macbook screen and then do a clean install. make sure that you don't have it save your settings and preferences just to be safe.

Jesse,  Do you think your suggestion would work using my install disk for CS6?  I just downloaded El Capitan last night and it's unbearable.  Thanks.  Sher
