After updating my late-2012 27" iMac to macOS Sierra Photoshop 2017 has been running very slow, beach-balling, and generally lagging behind on every action and tool. I use type a lot in Photoshop and notice it in particular there—setting type, resizing, font menu drop down/changing fonts, etc. It's to the point where it's basically unusable. I've already used all the Adobe tools to complete remove all CC Apps, the Creative Cloud app and miscellaneous files and preferences and re-installed but the issues persist. The other Adobe apps I use regularly (Illustrator & InDesign) seem fine. Can anyone help me?
