macOS 12.4 Update

Complete success, still on Clover. So pleased with the ease. Updated from 12.3.1, all fully automated.
Clover 5146 and up to date kexts.
I have been building and testing OC EFI's and they have worked. But I like the Clover boot screen, and haven't taken the trouble to try to pretty up OC. And every time I try OC, Apple cloud freaks out, thinking I am a new machine, so I try to leave the network disconnected in those trials. Anyway, all is well.

Happy to know the update was trouble free for you. If the eye candy in Clover is your thing, you can have the same in OC as well. Check out my OC Boot Menu pics. The other problem you mentioned when switching to OC messes with your Apple Cloud Logon is caused by a bug in Clover when converting to OC.

Clover inverts or changes part of the SmUUID data in the config.plist which causes the Apple Server to think that a new machine is trying to logon. This problem was discovered and discussed by a few members on another site, wether the problem was solved I don't know.

The work around to the problem is to check that the SmUUID was not changed before logging into any of the Apple Services.

Z490 Vision D + OpenCore 8.0 = No Drama..

OC 0.8.0 — macOS 12.4

No network issues. No GPU issues. No update glitches.

NVMe boot Trim on Samsung 980 Pro still slow.

Pleased to find 12.4 update fixes an oddity where kernel_task was constantly eating 30–50% of a core. This has been happening since I first build this kit with Big Sur 11.2. Now system fully idles and Geekbench5 gives best score yet with a 5–8% gain over previous bests:

EDIT: I just discovered by chance that this oddity is not about 12.4 update, but about booting from an OpenCore EFI on the same drive as the macOS installation.

Idk how I've missed this for more than a year...

To be clear: If I boot OC from another drive than target macOS, kernel_task is quiet at idle. If I boot OC from same drive as target macOS, kernel_task eats up to half a core.

I have no insights into what kernel_task its doing or why.

I discovered this by accident. I did a trial update of a backup, and noticed the improvement, then posted this. Later I updated my main drive and found no gain. The one difference between the backup and main was I had emptied the EFI folder on the backup. By booting OC from a flash drive, I found the performance fixed. It doesn't matter if EFI of target macOS has contents, it matters if booted from that EFI.

I'll start another thread.
