Anyone successfully running multiple monitors with Sequoia + OpenCore?

Hardware is:

  • Intel Core i5-8400 2.8Ghz
  • Gigabyte Z370n WiFi (w/Airport card)
  • Teamgroup 32GB DDR4
  • Radeon RX-570 8GB XXX Edition
  • Western Digital Black 1TB M.2 SSD
  • Mini-ITX case (so no room for PCIe WiFi/BT card)
  • Dell 27" QHD monitor using DisplayPort (primary)
  • Dell 21" HD monitor using DisplayPort (secondary)
  • DisplayPort to HDMI to 46" 4k HDR LED TV

So I've been running a Hackintosh successfully since 2018, first with Clover, then transitioned to OpenCore. My machine was practically a golden build (the only exception was DRM(, which I didn't need anyway). The machine worked superb, literally flawless for the first 6 years of daily usage. All Apple services worked, everything was pretty much the same as an "official" Mac.

...Then last year with the new MacOS Sonoma I lost WiFi + all WiFi-related features (Airdrop, Sidecar, FindMy) with Sonoma). I was okay with that compromise since everything else still worked as expected with Sonoma.

Fast forward to yesterday, we get the official Sequoia release, so I tested installing it with OpenCore 1.0.1 onto a spare SSD. Fired up the machine, got to the desktop, and it was not recognizing any other display except for the 21". I swapped the primary and secondary displayport cables on the back of the RX-570 and that moved the Sequoia desktop to the primary 27". In Settings it only shows 1 monitor connected. I swapped back to my current Sonoma SSD and everything is back to working again as-is.

I was a little sad last year because Sonoma was the first MacOS that I lost features (expected, since full-featured Intel-based Hackintoshing is an its tail-end thanks to Apple Silicon). I already prepared to transition to a real Apple Mac Mini or Mac Studio, if I can't get multiple monitors working that might be my signal to move on.

Any ideas?
