You get the boot screen with a Mac flashed Metal GPU like I have.

If you already have a Mac flashed metal GPU, just GPU video acceleration. I have a generic RX580, so having a boot screen and volume picker was a huge plus.

For sure.

Besides that does OC add anything else to Mojave?

Off the Wall provided two great links to read.



Most part it also show your PCI drives as internal.


here's the technical list of Martin Lo's configlist.

1. Boot screen (via GOP for unflashed card, including some Nvidia card)
2. Firmware protection (to run Windows in EFI mode without risking the cMP bootROM)
3. HWAccel (H264 / HEVC hardware decode + encode in Mojave and newer macOS up to Big Sur 11.2.3)
4. ability to watch DRM streaming content (Mojave and newer macOS up to Big Sur 11.2.3)
5. Boot picker (only support EFI systems, tested with Apple wired keyboard, Magic Mouse, and Magic Keyboard, 10s timeout. If you can't see this. Just don't touch the keyboard, and your cMP should continue to boot to desktop)
6. NVMe and SATA drives on PCIe card show up as internal
7. Support for Apple USB SuperDrive
8. TRIM (regardless trimforce status)
9. Ability to run non-GUI 32bit software in Catalina
10. Ability to reset NVRAM in boot picker (disabled at this moment to align with the native Apple boot manager)
11. Ability to run any natively supported ancient OSX with modern graphic card e.g. Radeon VII in 10.6.8 (only can display, no acceleration) [Update 5th May 2020: Sierra and High Sierra may not fully supported yet. Thanks for pierrox's report]
12. Ability to boot Catalina / Big Sur Recovery Partition
13. Sleep should work (tested on my cMP, but I can't guarantee it also work with your hardware)
14. Possible to run 8x32GB RAM in macOS (user need to mod the config.plist manually. Replace the false below CustomMemory to true)

That's pretty good.

Martin is a good guy. I've known him for a couple of years

Absolutely, him and Alex been a tremendous help.


Off the Wall. I see you are having trouble with the EFI on the nVME ?


Get it resolved ?. I went through that as well. I just made sure I did the 5 chimes, removed all peripherals on the initial install first boot, and I overlooked by accident disabling SIP.

Off the Wall, you get the NVMe squared away with OC ?


I plan on setting up the OC on a USB. I read on that and it's a great way to keep it from messing up the EFI volume on the OS drives.

No, I just run it off one of my SATA drives. Works great.

Very cool. I was doing the same but I'm switching to USB. From what I read it really helpful if something goes wrong just ZAP the Nvram and pull the USB then you back to normal.


You still on Catalina, or did you jump to 11.2.3 ?


Thanks and have a fantastic week.

No going to stay on Catalina for now unless a future 'current' version of 11.x works reliably on the 5,1.

Hey Off The wall. Did you do the Thunderbolt mod?

I don't have any PCI slots left!
