Could this be why Clover is not seeing the partial install after the first reboot?

Or should I dump Clover and go with OC?
Your choice. CLOVER r5122 / Catalina 10.15.7 (19H15) is still my stable baseline where I spend most of my time. If you want to run Big Sur, see this thread and use OC (for now).

CORRECTION: Before and after the update to USBPorts.kext, I see the "accessory needs more power" message when I plug my iPhone 7 into the left front USB3 port. If I switch ports and plug the iPhone 7 into the right-front USB3 port, I don't get the error message.

Does anyone else see this same USB behavior?

I may have. I remember having seen this message before and it was not very reproducible. I haven't seen it since so you are likely right!

Congratulations!

EDIT: @jccds - I just performed a clean installation of Catalina 10.15.7.02 with the CLOVER EFI attached to Post #1. It worked without any issues. If you are certain that you followed the installation instructions, I'm not sure why you experienced problems when installing Catalina with CLOVER r5122. I'm glad that OpenCore worked for you. As you learn more about hackintoshing, if you determine the cause of the issues you experienced, please share them as your lessons learned may help others.

First of all, congratulation are for you and rafale77.

I never tested clover, went straight with OC. Do you advise clover vs OC?

I got my conversations mixed-up. That comment should have been for @Squeaky . CLOVER/OC is your choice.

Was browsing GeekBench 5 scores for the New MacMini (Apple M1 Chip). If the benchmark is consistent across platforms, the new MacMini is comparable to the i9-based hacks.

The single core is actually significantly higher (30-50%) than the i9. The Multi-Core is between the 9900 and the 9900K. It's pretty impressive.

A separate note about the HP EliteDesk 800 G3 Mini
I just picked up a like-new HP EliteDesk 800 G3 Mini / i7-7700T / 16GB / 256GB for $280.00 US. This is very off-topic, but if this runs MacOS, it might be an incredibly cost-effective Hackintosh. For those who stumble upon this thread while hacking your EliteDesk 800 G3 Mini, you've undoubtedly noticed that the G3 Mini BIOS does not have separate controls for Intel ME. I was checking the Intel ME firmware version on my G3 Mini and found that I could only "see" Intel ME when "Remote Management Options" > "Activate Management (AMT)" is checked / enabled. Since I found that HD Graphics sleep/wake requires Intel ME on the G4 Mini, I'm guessing that AMT must be enabled on the G3 Mini.

I confirmed in Windows 10 that Intel ME appears in Device Manager only when AMT is enabled in BIOS. If MacOS installs and runs well on the G3 Mini with minimal changes to the G4/G5 EFI, I'll post the solution in this thread. If it's much different, I'll create a new thread.

Notes about the G3 Mini Install
Best SMBIOS MacModel for my 800 G3 Mini is iMac18,2 iMac18,1 or MacMini8,1: still testing
  • After latest BIOS update, needs this ACPI patch to boot MacOS
Catalina Install Notes
  • Experimented with various SMBIOS MacModels (iMac18,2, iMac18,1, MacMini8,1) and found it easiest to test HD 630 graphics patching with MacMini8,1. After testing with SMBIOS MM8,1 and finding working AAPL,ig-platform-id / framebuffer-conX-indices / framebuffer-conX-busids, I'm able to switch to iMac18,1 to test power management
Sleep remains elusive on the G3 Mini. With SMBIOS iMac18,1 and what I think is correct USB patching and correct Framebuffer patching, G3 Mini won't wake after sleep (it sleeps with flashing power light, but attempt to wake with keyboard or power button results in illuminated power LED, but no disk activity, dark displays and inability to Remote Desktop into the unit). After wake, must force shutdown (hold power button) to recover. Otherwise, this G3 Mini is an awesome deal for a mostly functional Hackintosh.
