Hello! First, great work on creating and updating these guides!! Thanks to you I finally decided to install MacOS on a PC, as I happen to have an Elitedesk mini G4. I started with Dortania's Guide and had some problems with drivers so I downloaded your EFI folder and with that I installed Catalina with no problems. Is it possible to upgrade to Big Sur with Apple's tool in System Preferences? I didn't find much info on upgrading to Big Sur just fresh install but it seems it still has many issues.

Sounds like a great setup! I haven't seen any other posts in this thread regarding Thunderbolt and I don't have that Flex IO port in my system. I would recommend that you search for other Thunderbolt threads (like this one) and post your questions there. In my opinion, as long as you have a supported Thunderbolt chipset, your solution won't be specific to the G5 DM, so you should be able to seek advice from others who have working Thunderbolt in different systems.

BTW - it's great to know that the Thunderbolt option exists in our EliteDesk Minis. One more expansion option that makes these little PCs such great hacks.
The Thunderbolt option is a wonderful choice, if you ordered your mini directly from HP with it. I'm not from the US and it's very difficult to get one of these.

Glad you found this useful! If you're posting in this thread, then I assume you're booting with OpenCore. What happened when you tried to upgrade Catalina to Big Sur?

Yes I'm using OC, I haven't tried updating didn't want to mess up. Dortania's guide says there are still issues with Big Sur in general. Is it better to stay in Catalina for now? I want a relatively stable system for everyday use.
I have another SSD lying around so maybe I can use it for testing

I think that is a smart strategy. I'm still running Catalina as my baseline and I have a sepearate SSD for OC testing. I probabably won't be switching to Big Sur until incremental release 4. It's definitely an individual decision.

Hello all,

i've got this Post Error with OC from start till 0.65 nightly too.
I use RTCMemoryFixup.kext and Nvram boot args rtcfx_exclude=B0-B4 to solve this.

I saw different Setups why you use:
darkwake 2
ReleaseUsbOwnership true
layout-id 14000000 instead of alcid=20

Microphone still not working with the new AppleALC.kext

i use macOS 11.1 with Samsung SSD 970 EVO Plus 500GB without NVMeFix.kext and running well!

I am also using rtcfx_exclude=B0-B4 and would like to narrow this down if possible. Have you conducted any experiments to see if we can use a narrower exclude range? In the RtcMemoryFixup.kext Readme, they indicate that they only needed rtcfx_exclude=B2, but I haven't tested yet.

I saw different Setups why you use:
darkwake 2
ReleaseUsbOwnership true
layout-id 14000000 instead of alcid=20

darkwake=2 is correct. I had tried darkwake=3 at someone else's recommendation, but it didn't make a difference. I am also currently running with darkwake=2.

OC's ReleaseUsbOwnership true is the same as CLOVER's USB:FixOwnership. I set this in my original CLOVER configuration for Catalina here and kept this in my OC implementation in this thread. It doesn't hurt, but it may not be necessary.

layout-id 0x14 (hexidecimal) is the same as alcid=20 (decimal). You can specify layout-id in the DeviceProperties or alcid in the boot-args. I prefer to specify layout-id in the DeviceProperties to keep all of the audio and graphics device properties in one place. It's a personal preference.

Big Sur definitely is introducing some minor quirks along with some nice features. I am not seeing major issues though and have been running it as my daily driver on my hack and my other macbooks as well.

question to thunderbolt:

i think, that we could buy this chipset from HP.
Do they use the same USB C connector?
that would be a great think to get eGPU´s working.

Is there a way to run macOS with Bitlocker?
