Thanks. Not Sure if that was it, or if logging out and back in to iTunes that did it. It din't work right away, but once I re-logged in, it seemed to work.

I seem to have another issue. iTunes Streaming will not play. Is this a DRM issue? Any suggestions on how to fix this?

Thanks for the help!! Donated!!

WOW! That worked! Both monitors working now, and I think USB is working too. Haven't tested speeds yet to see if I'm getting full USB3 speeds, but so far, everything seems to work. Do I need to change the platform info in the plist?

actually, just discovered that most of my USB ports are also not working. Tried to do the USB mapping from the guide, but obviously got something wrong.

My Build: ASUS ROG Maximus XI Hero (Wifi) Intel I9-9900k PowerColor Red Devil Radeon RX Vega 64 32 GB Ram G.SKILL TridenZ RGB Series 32GB (4X8) (PC4 25600) and i swapped the stock wifi card out for a Broadcom BCM94352Z DW1560 802.11a/b/g/n/ac WLAN + Bluetooth 4.0 M.2 NGFF Mini Card 867Mbps Recently upgraded from Catalina to Big Sur - switched from Clover to Open Core on this one. So far, everything *seems* to be working except that I only have 1 monitor working (connected via hdmi) instead of 2 My other (main) monitor connected via display port does not work once booted (it does work to view the BIOS and during boot). The boot args that I am using are : keepsyms=1 shikigva=40 shiki-id=Mac-7BA5B2D9E42DDD94 any suggestions would be greatly appreciated. Thanks.
