This fixed it for me https://www.tonymacx86.com/threads/not-getting-system-prefs-12-3-update-notification.319602/post-2314850

I have the same problem. I found that if I change the system definition from iMacPro 1,1 to iMac19,1 system update works. I do have SecureBootModel set to disabled.

Did you ever resolve this? I am having software update problems after updating to opencore 7.7

Ended up updating opencore and redoing config.plist. All good now.

Thanks. Tried that. Added -no_compat_check to boot-args under 7C436110-AB2A-4BBB-A880-FE41995C9F82 Still get the error.

Thanks. I did change it to iMac17,1 but got the same error. How do I use the boot flag, I'm using opencore, btw.

I cleaned up a bit of my config.plist, restarted and my computer worked fine. I reset nvram and now I get "This version of Mac OS X is not supported on this platform!" I can start up using my USB drive and replaced my EFI from a back up, but I still get the error. I'm on Big Sur, I ran my...

Yes it's strange, if I take the patch off the eject key works. I have 2 internal ssd's and the dvd drive connected to a sata card, the drives show up as removable as well as an hdd that is in a hot swap caddy. I put the eject icon on my menu bar and it works to open and close the tray, so I can...

I did this and hot plugging now works, thanks, but after making these changes the eject key on my keyboard doesn't eject. It works as a shortcut as for putting monitor to sleep but not to activate the tray. Any ideas? Thanks.

Mount the EFI partition using Clover Configurator ore somesuch. On original drive, mount EFI partition. Mount EFI partition on new drive, copy EFI folder from original drive to EFI partiton on new drive. That's pretty much all I got.

no need to reclone. just add the EFI folder to the EFI partition.

you have to copy the EFI folder/partition. CCC doesn't do it. When you have both drives in the computer its reading the EFI folder from your old drive which is why it works.

Did you copy your EFI partition to the new drive?

Wow. Thanks so much for sharing this. I made these changes and a video I had previously processed that took 52 minutes took just 6 and a half minutes after I made these changes. Incredible. And I do a bunch of video processing. Thank you!

Figured out my issue. I recently cloned my start up and EFI to a new M2 drive but left the old drive in as security and bios was reding the EFI from the old drive but I was editing the the EFI on the new drive...

Thanks. Yes, I did all that. Still shows the same mapping. I even tried downloadingand installing a .aml file for my motherboard that has the port I need mapped, but it still shows the old mapping.

Thanks. Yes, I followed that guide but Hackintool still shows my original port mapping even after reinstalling USB inject all and raise port limit patch.

I recently installed a Fenvi wifi/bluetooth card. I need to use the usb 2 header on the motherboard to connect Bluetooth, however, when I initially mapped the USB ports I ignored the internal USB 2 headers and when I remove the .aml file and add USB inject all, to try and remap the ports, it...

Did you ever figure this out? I have the same set up and similar problem.
