@pastrychef - I'm stumped with my Z390 Gaming X / i9-9700K / RX-580 build.
It was booting fine yesterday (19,2 SMBOIS) to 10.15.5 with dual monitors (DP and DVI), but when I tried applying the recent supplement update, that somehow fouled up and never completed, leaving me with an unbootable hard drive.
I made a new UniBeast installer and re-installed everything the same, but now when leaving Clover, it only boots maybe 1 out of every 5 tries (maybe less) and most of the time I immediately get the "prohibited" sign after the bootloader.
I've tried changing the SMBIOS around (19,1, 18,3, and 17,1 - no changes) and am back to 19,2 since that seems to be the only one where dual monitors work.
My motherboard is slightly different, and the only kexts I have are:
- Apple ALC
- IntelMausi
- Lilu
- WhateverGreen
- VirtualSMC
- USBPorts (custom after using Hackintool guide)
Besides the boot issue, my USB 2.0 ports are not active (but they work fine in BIOS).
Any suggestions you might have would be greatly appreciated.
