[GUIDE] Catalina on HP EliteDesk 800 G4/G5 Mini - The Perfect MacMini8,1 Hackintosh - CLOVER & OC

Fair enough. I am making an attempt at upgrading to BS for now. I tested also your ACPI implementation and couldn't really make up any visible difference. I just wasn't sure if there was a benefit to switching.

I was even looking at modifying the bios HP logo... but it doesn't appear to be possible.

Big Sur just installed on my HackMini8,1 with minimal issues using my EFI here. During install, I experienced loss of real time clock (so I have some tweaking to do), but this never resulted in loss of any BIOS settings and it recovered without me taking any action. The RTC issue was only an annoyance, but not a show stopper. What a painless upgrade! I haven't tested, but BS looks promising on our rigs!

I have changed the title of this thread to include Big Sur.

I performed the update when prompted and just followed the steps. No special actions necessary (except ignoring the RTC issue).

I'm not experiencing any RTC issues after the BS install. Restart, shutdown, sleep/wake all working without issues. Granted, I've only performed minimal testing, but this is an incredible first experience with BS.

Also, I can boot BS Recovery - something I've never done before (with CLOVER).

GeekBench 5 CPU results are same in BS as in Catalina.

I managed to customize the BIOS logo. This is painful to figure out. The logo swap requires booting from windows, installing a powershell library, create a 1024x768 apple logo and run a powershell script.

Download and install
HP Client Management Script Library from here

Open windows powershell in secure mode and run

Set-HPFirmwareBootLogo -file custom.jpg

you may need to allow the library to load with this command first if you get an error:

Set-ExecutionPolicy RemoteSigned

Attached is the logo I used.

And Big Sur update was successful here too!
It's pretty funny to see the machine boot into windows showing the circling dots with the apple logo on top.
Attached another good logo.

There are enough fixes on Big Sur for me to switch out of Catalina. I had some weird problems on Safari14 with several of my server GUIs crashing (for example home assistant) which is fixed on 14.0.1. So far none of my "tweaks" broke and everything seems to be working a bit smoother. It was actually funny that the upgrade on my hack went smoother than the upgrade on my 12" macbook. And yes I too am using OC. I obsoleted Clover since I switched to the 800G5.

PS: Time to move this thread to the Big Sur section maybe?

@Stork is there a way for this thread to appear in both the Catalina and Big Sur Desktop Forums, or do we need to create a new Big Sur thread. It would be ideal if we can create a "link" thread in the Big Sur Desktop Forum that points to this thread, since there will be overlap for a while.

 

[Stork]

...do we need to create a new Big Sur thread.

Yes. Create a Big Sur Guide thread.

 

[deeveedee]

A new thread dedicated to Big Sur on the HP EliteDesk 800 G4 / G5 Mini has been created here.

@Stork At the time that I created the Big Sur Thread, there was not a tag for "Big Sur"
