Lightroom classic 13.0.1 has rendered my 2017 iMac 27" excruciatingly slow as soon as I work more than 3-4 masks. Help please!

    1. Please do the LR menu command Help > System Info and copy/paste the entire contents here so we can see exactly which versions of hardware and software LR thinks you're running and important LR options that are set.

     

    2. Click the Apple icon in the upper-left corner and do About This Mac. Post a full-resolution screenshot (not a phone pic) of the About window.

    Your hardware far exceeds LR's minimum requirements for graphics processors (many older Macs don't):

    And it appears that AMD is still actively supporting graphics drivers for the Radeon 500 series.

     

    Unfortunately, I don't have any suggestions for how to troubleshoot -- perhaps others do.
