Thank you so much for your response. It looks like I'll be going with either an RX 570 or 580 because they have more outputs and I'll be able to utilize all five of my screens. Those two cards seem to work so I think I'll be able to update to Catalina soon!

If you are not in a hurry, AMD should be releasing the 5500 cards soon. They are Navi cards and are much more modern than the RX 570 or 580. They should also be cooler running and consume less power.

Thank you for flagging this! I'm definitely not in a rush to update, it'll just be a nice to have. I haven't updated since following your initial guide, waiting another month or two won't change much.

@pastrychef can't hide my Windows Drives on Clover boot. I always wrote "Windows" in the hide section, normally it been worked after the restart but now it looks never affect it.

Sorry. I don't know. I never try to hide any of the volumes.

For the last 2-3 months, I had my i9-9900K and my Radeon VII in my Gigabyte Z390 M Gaming motherboard and it was my primary system. I tried to live with lack of NVRAM. I tried to like the better VRM. I tried to fix the weird RAM issues I was having (for over 3 weeks). I really, really tried to like this motherboard.

Las night, I threw in the towel and spent over 5 hours reverting back to my beloved Asus ROG Z370-G Gaming. It feels so good to have everything working again.

My experiences with the Gigabyte Z390:
  • Overclocking the CPU was good. I got a stable 5GHz on 1.275v with LLC 6. On my Asus Z370, I need 1.320v on LLC 5.
  • RAM on my Z390 was completely screwed up with BIOS F8 (currently newest). My RAM, which is on Gigabyte's QVL list, would not run at its XMP profile stably at all. I constantly had random freezes. I tried to adjust timings and lower the clocks and could not get the system stable until I lowered RAM speed to 3066MHz. That's 333MHz below the advertised speed of 3400MHz and brought my GeekBench scores from about 9700+ down to about 8800+!! :thumbdown
  • The excessive freezes allowed me to fully test the booting consistency on this Z390 motherboard. On OpenCore with IGPU disabled, it boots 100% consistently. On Clover, with or without IGPU enabled, the best I could ever get it to do was boot about 80% of the time.
  • There's no way to get the CNVi slot to work with any Wi-Fi/Bluetooth card other than an Intel CNVi card.
  • Thunderbolt worked well for me. I didn't experience any problems with it.
  • My Syba 10GBase-T PCI-e card never worked in the Z390.
  • System stability was better with BIOS F7, but booting was more consistent with BIOS F8. :banghead:
  • One SATA port is disabled if the second NVMe slot is used. This was not noted on the specs page on Gigabyte's website.
  • Having Wi-Fi/Bluetooth on a PCI-e card doesn't work quite as well as when having it on the motherboard M.2 slot. When it's on a PCI-e card, it takes multiple clicks of my Magic Mouse 2 before the system fully wakes and the mouse is actually active.

Getting the Z390 motherboard working semi-correctly with macOS involved so much more work than on my Z370. I really spent more time troubleshooting and fixing than using the system. I had to change the hidden CFG Lock setting in BIOS with each BIOS update. On the Asus, CFG Lock was disabled from the factory.

What did I lose by reverting from Z390 to Z370? Thunderbolt. But the only reason why I installed Thunderbolt was because my 10GBase-T card didn't work on the Z390 and I had to use a 10GBase-T to Thunderbolt adaptor instead. Other than that, I lost nothing and regained 100% stability and considerably better performance because my RAM can run at its XMP speeds.

So, I reaffirm my stance that, from a hackintosh perspective, Z370 is MUCH better than Z390. Any of you guys who are currently on Z370 and are considering Z390, just don't do it!


Btw, my Radeon VII suddenly decided to wake properly when installed on my Asus Z370-G! Why? I have no freakin' idea why...

Nice article. What I can say, or rather add, is that the Asus Z370-A supports Thunderbolt, and a lot of the Z370 Gigabyte boards support Thunderbolt as well (if you need it). Sounds like you don't need it, but in case others might, I think its worth mentioning that many Z370 boards do support it.

To put this in perspective: I have had very good luck with my Z390 Designare rig. There may be no native NVRAM but it was/is quite easy to install/upgrade/tweak/use. Best Hack I've had. Even sleep works. Well, sometimes. Thunderbolt is usable (hot swap for my devices).
There are lots of other Designare users guided by the mighty CaseySJ... So lots of info.
IMO, a fine choice for a hack mobo.

Exactly my thoughts. When I first bought the Gigabyte Aorus Z390 Pro Wifi, it worked but not reliable enough to use the machine for work related tasks. I ended up returning it. I'm super happy with my Asus Prime Z370-A II, and I went with that one because it has Thunderbolt 3 Header so you can hook up an Alpine/Titan Ridge there (in my case to make the LG 5K work at real 5K).

Thanks for all your work @pastrychef

Which Aptio fix are you using? I was never able to get any of the Aptio fixes to boot consistently with Clover except OsxAptioFix2-free2000.efi. But, as we all know, that Aptio fix should not be used.

Sleep worked fine for me. Thunderbolt worked even with hot plugging.

RAM was a big problem for me. After doing a bit of research, I found that I'm not the only one to have RAM issues on Gigabyte.

The Designare might be a fine motherboard, but there's better. Namely, those with NVRAM support.
