You might find out that iStat Menus won't work with iMac20,2, but you may well know it already. Doesn't work on iMacPro1,1 either but it does when using iMac19,1.
Can I ask you a question?
If disabling the iGPU, do you believe the x264 encoding using Intel Quick Sync would be carried by the installed AMD card? Do you see any advantage in that?
Fortunately no beachball in 11.5 public beta. Because 11.4 is officially released, are you planning to update soon?Anyone want to explore a macOs 11.3x bug with me? Open a PDF in preview, then search for a word. with the word still in the search bar, try to highlight some text (to copy/paste). This results in a beachball for me... anyone else?
