My current baseline for this rig is still Catalina 10.15.7.03 with CLOVER r5122. After much effort to maintain two candidate baselines for both CLOVER and OC, I have decided to drop CLOVER in favor of OC as I migrate to Big Sur. I'll migrate to Big Sur when it reaches incremental version 4 and plan to have an OC bootloader solution at that time. Many thanks to the CLOVER Team for their great work and to everyone in this forum for the outstanding CLOVER support. It's been an amazing journey!

To switch from CLOVER to OC, do the following:
  1. Make a full system backup before you convert
  2. Open Hackintool and collect the following info (collecting this from your CLOVER config.plist is possible, too, if you can avoid the confusion of RtVariables.MLB and SMBIOS.BoardSerialNumber):
    • Serial Number (this will be OC's PlatformInfo.Generic.SystemSerialNumber)
    • System ID (this will be OC's PlatformInfo.Generic.SystemUUID)
    • ROM (this will be OC's PlatformInfo.Generic.ROM)
    • Board Serial Number (this will be OC's PlatformInfo.Generic.MLB)
  3. Follow this guide to remove the CLOVER stuff from your system: Converting from CLOVER to OC
  4. After you have completely removed the CLOVER EFI from your system, replace it with your OC EFI
  5. Populate your OC config.plist with the values you collected in Step 1
  6. Reboot (now with OC bootloader)
  7. Follow any prompts to allow extensions for apps that you've installed

Glad this guide is working for you! Are you referring to the 512mb memory setting in BIOS? If so, I'm not aware of a way to increase this. If you want macOS to report more or less video memory, you can play with DeviceProperty framebuffer-unifiedmem as described here. I have seen recommendations to increase framebuffer-unifiedmem with 4k displays, but I don't have any 4k displays, haven't tested this and have not observed any difference in video performance when changing framebuffer-unifiedmem.

If you need more help, please post your problem reporting files with your request as mentioned in Post #1.

The Catalina security update and Safari update installed without any problems. My current baseline is Catalina 10.15.7 (19H512) and OpenCore 0.6.5 (using EFI OC0.6.5-EFI-r002.zip posted here).

My OS baseline remains Catalina 10.15.7. I am now booting with OpenCore 0.6.6 using EFI attached here.

The Catalina 10.15.7 (19H524) update was flawless - no issues. My baseline is still Catalina 10.15.7 and I'm booting with OC 0.6.6 (EFI attached here).

iMovie 10.1.16 runs great on this HackMini running Catalina 10.15.7. Editing is smooth and rendering is fast. I have found that after exporting (sharing) the final video, it is a good idea to reboot. The entire system starts to slow down. Since the slow-down is systemic and the slowdown occurs without much CPU or Disk activity (as measured by Activity Monitor), the slow-down could be a video driver issue. iMovie issues are known on real Macs, too, so I don't see this as much of a problem. Just reboot after exporting the final video.

Hi @deeveedee , first of all excellent work ! I have a HP Prodesk 600 G5 mini, but with a diferente EFI -> https://github.com/romancin/HP-ProDesk600-G5-mini-OpenCore . Its working well except microphone which i didnt make it to work... And the EFI/Config i have is outdated, so im thinking about testing your's , for that i will put your EFI in a USB pendrive and try it, if OK i will start using yours.

Should i use the OC0.6.6-EFI-r003.zip or OC0.6.6-EFI-r002.zip ? whats the diference ?

Look here for the revision history. Within each .zip archive is a file "changes.txt" that provides more detail. Good luck!
