I've been experiencing extreme lag the last year or so with Photoshop and Premiere on my late 2012 iMac currently running High Sierra 10.13.6. I just tried installing the latest versions, deleting all old versions and preferences, and the issues persist. I'll perform a task as simple as dragging or resizing an object in Photoshop and it will freeze up and show a loading bar for a few seconds. Never had these issues until the last year and a bit. Anyone else?
