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

...
The Big Sur Disk is showing up on the OpenCore Boot GUI named as 'Preboot'. Also when I boot Catalina I just see a folder called update and no Big Sur Disk.

Both of these are normal. Big Sur introduces enhancements to APFS that are not recognized in Catalina.

I am still seeing my Catalina Disk named a 'parallels' on the OpenCore Boot GUI.

Where are these strange names being stored?

Probably good to raise this issue over at Insanely Mac in the OpenCore thread.

I have all three M2 slots filled and I am having constant problems with boot. The vision D hangs either right before the bios setup message or after. I usually need to turn off the power supply to get it to boot. At first boot in the morning it starts up normally. From cpu slot to last; Samsung 970 1 TBwindows, Sabret 2 TB, Catalina, Samsung 970 2TB, AV drive. Last PCEI Slot, M2adapter with 500GB Sabret NVMe.

Have you contacted Gigabyte Tech Support?

I received a new Silicon Power 512GB NVMe SSD couple of days ago that I can install into the M2A slot and see what happens.

Current Config:

• M2A - empty
• M2M - Silicon Power 256GB NVMe (Big Sur)
• M2P - Sabrent Rocket 256GB NVMe (Catalina)

New Testing Config (for later today):

• M2A - Silicon Power 512GB NVMe
• M2M - Silicon Power 256GB NVMe (Big Sur)
• M2P - Sabrent Rocket 256GB NVMe (Catalina)

From cold boot to Picker Menu (I've got the splash screen disabled) : 20s
From OC to Login: 44s
From Login to Desktop: <15s

According the the logs the main culprit appears to be IONVMeFamily (23s). I'm using a 1tb 970 evo for the Mac side of things - could that be the issue?

Hello @crossmoid,

Can you please post the subsection of log messages that points to IONVMeFamily.

Well, NVRAM seems to be working fine. Time to check with FV2 disabled.

Is the situation any better with FileVault (FV2) disabled?

So far it hasn't happened again. But I'm not ruling it out. Even with FV2 enabled, it happened erratically.

Well, I'm pleased to report that the system is working perfectly fine with all three M.2 slots occupied. Just had to perform a Reset NVRAM (always a good idea when changing disk configuration).

This system also has:

• AMD RX 580 in PCIe slot 1
• Fenvi FV-T919 in short slot
• GC-Titan Ridge Thunderbolt 3 card in bottom PCIe slot

In addition:

• Silicon Power 256GB SATA SSD connected to internal SATA port (Windows 10)
• Silicon Power 256GB SATA SSD connected to internal SATA port (Kubuntu 20.04 Linux)

So it's running:

• Catalina
• Big Sur
• Windows
• Linux

Be sure to remove the blue plastic wrap behind each of the M.2 covers/heat sinks.

970 Evo Plus is known to take longer for booting in macOS. The latest firmware fixed the ability to use it but it still has longer boot times (1m vs 30s) compared to other SSDs.

NH-D15 is incompatible with Vision D - https://noctua.at/en/mainboard/Gigabyte_Z490_Vision_D
It blocks the first PCIe slot which might be a deal breaker for hackintoshing (now or in the future)

Is the situation any better with FileVault (FV2) disabled?

So the cause was not FV2 but an incorrect slide value choosen by opencore. I have to set "ProvideMaxSlide" in config.plist to ensure that OC does not choose a value from a range which results in the error.

My particular Vision G's memory layout has only 187 valid of possible 256 values. Between 0-156/159 and 223/229-255. These values keep on changing but if OC chooses a random value from the 229-255, then booting is a no go. I have so far set ProvideMaxSlide=120 but I still need to check for higher values.

For those who land on this later, use the debug version of opencore to see what slide values are calculated by OC if you have a Halting on Critical Error with something like
AAPL: [EB|‘LD:LKC] } Err(0x9)

Both of these are normal. Big Sur introduces enhancements to APFS that are not recognized in Catalina.

Probably good to raise this issue over at Insanely Mac in the OpenCore thread.

Thanks.

I have done that but no response yet.
