Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

Unfortunately, this time it didn't work!

The weird thing is that in the subsequent reboot I used the ClearNVRAM EFI module of OC, and, then, I got what you can see in the first pic attached. Then, after another reboot, I got what you see in the 2nd pic attached. In the 3rd reboot it passed the verbose initial phase, and I got the graphical interface. But, during the install process, it stopped again with the message of damaged installer... I don't know... but I have the feeling it's an NVRAM issue. But I cannot resolve it!

Is your system connected to wired Ethernet? If not, give that a try. No guarantees, but if that doesn't work then the next option will be to install macOS using a different Hackintosh or a real Mac. That means installing the SSD from this Hackintosh into an external USB enclosure, for example, and connecting it to the real Mac or other Hack.

Hi there,
I am using Z390 Aorus Pro, and this motherboard has a well known USB drop problem that causes freezing. (The PC is still working but I can not use trackpad, keyboard.) This problem is really annoying.
I am planning to upgrade to Z490 vision D with i7-10700.

1. Could you tell me whether this motherboard has that problem?
2. I have checked your EFI but can not find USBMap kext. Have you not mapped the USB ports?

Hope you can answer my questions.
Regards

The Z490 Vision D does not have the USB drop problem, but the Z390 Aorus Pro shouldn’t have that problem either. As long as a maximum of 15 ports are mapped and an older BIOS is installed (one that does not support Resizeable BAR) then it should work reliably.

For any other questions about the Z490 Vision D (including the way USB ports are mapped) please see Post 1.

There have been some reports of incompatibility with WD SN750 NVMe SSDs. Sometimes moving this SSD to a different M.2 slot can help.

Three suggestions:

1. Try disabling NVMeFix.kext from the Kernel section of OpenCore Configurator. Reboot and check if the problem still occurs.
2. If problem still occurs, try moving the SSD to a different M.2 slot.
3. If that also does not help, physically remove the SN750 and temporarily use a different NVMe SSD or even a cheap SATA 2.5" SSD.
   • If macOS installs and runs smoothly on the temporary SSD, then it might be best to return the WD SN750 and purchase an alternative instead.
   • The NVMe SSDs I recommend are:
     • ADATA SX series
     • Silicon Power
     • Sabrent Rocket series
   • Other brands are also good, but to be safe I would suggest staying away from:
     • Samsung
     • WD

I bought a WD SN750 last year, after years of buying Samsung. It works well with macOS, gets 2700 MB/sec read write (via Thunderbolt). Mainly because of how long Samsung drives take to execute the trim command at macOS boot time. Also, the Samsung 970 EVO Plus runs a bit warm so I wanted to test a different brand.

I bought another WD SN750 this year, to use as a test drive (for beta OS purposes), and it seems like the firmware or controller has changed. The drive only writes at 730 MB/sec max, doesn’t matter if it is in a Thunderbolt enclosure or directly attached to the motherboard. Doesn’t matter if it’s Windows or macOS. I tried different motherboards, same issue. I sent it back. so write speeds are affected, not read speeds.

Can be that Western Digital changed something in their manufacturing process. And it’s very curious that the advertisement on the box is for the read speed, and they’re silent about the write speed. Very annoying.

Thank you so much for your quick reply.
Unfortunately, I am using the latest BIOS version on Z390 Aorus Pro, so it should have the Resizable BAR ((. I already have the USBMap kext 15 ports but the problem still persists. I have checked a lot of forums but no one seems to solve the freezing problem.

We recommend older versions of BIOS that do not have Resizeable BAR support. It is perfectly okay to install older versions of BIOS.

Might be worth checking if your Asmedia ports are connecting to the right driver. I had this issue moving to Big Sur, and it took awhile to track down. Even when I wasn't using those ports.

If so, try the Asmedia.kext floating around.

I didn't know that. I will try to reinstall an older version. Thank you very much.

Hi NorthAmtransAm,
This is the first time I heard Asmedia.kext. Could you tell me the functions of the kext? I am using Catalina 10.15.7 (latest one), Big Sur seems to be a bit lagging for me so I downgrade to Catalina.

BTW, could you tell me the section in BIOS that contains resizable Bar? I hope Z390 and Z490 BIOS have similar sections.
