Wrong!

The patch I provided you originally in the post was correct. There was a typo in the patch implemented in the guide, which I now corrected.

Find and Replace values MUST have SAME amount of digits! Logics, isn't it?

Thus the correct patch is:

C1E30848 63D389D0 48C1EA20 B9990100 000F3048 FF0579C8 6B004883 C4085B5D C3662E0F 1F840000 000000
B800FF00 004863D3 89D048C1 EA20B999 0100000F 3048FF05 79C86B00 4883C408 5B5DC390 90909090 909090

And don't tell me that I cause you issues. At first place I try to help. And at second place there is a new EFI-Folder on Github where the patch is directly implemented in the config.plist!
Reverted to prior Performance patch, now that firmware is updated in bios. Performance is just about on par to the pre-Apple SU and has been running stable the past 24hrs+.

The Performance patch for SU causes my setup major performance hit not sure as to why, but it does. And on that note, issue closed.

Total revision of my former XHC USB Kext Creation Guideline

Note that I just finished a major revision of my XHC USB Kext Creation Guideline in the spirit of the 10.14.1 com.apple.driver.usb.AppleUSBXHCI USB port limit kernel patch flaw.

Enjoy and have fun,

Attached below a revised version of your EFI-Folder originally attached to post #2577.

I basically removed all unnecessary kernel patches, not only by also assuming that your MSR register is unlocked.

If this EFI-Folder does not reveal the expected performance, there is still something at odd with your microcodes.

BTW.. the 10.13.6 XCPM_performance_patch is not supposed to work with 10.13.6 SU.

With this, the topic is also closed from my side.

Cheers,

KGP

Booted up with that which you provided. It seems my cpu stays at 1.2Ghz only. Now the prior performance patch put it around 2.94Ghz with a few little peaks above 3.6Ghz, but is around 2Ghz to 2.5Ghz mostly. (via intel power gadget) when I run geekbench and cinebench.

The Asrock motherboard I have doesn't have a CFG-Lock register. So with your config.plist I had to check KernelPM and enable the core you had set to disabled. My prior config.plist had that xcpm_program_msrs in it where I didn't have to enable the core scope msrs and KernelPM.

Booted up ubuntu on a usb stick and ran geekbench on it to compare the score.

https://browser.geekbench.com/v4/cpu/10605470

Makes me wonder if I should put ubuntu back on it! Incredible score from a usb stick using live linux with bare configuration.

Hi KGP,

I'm jumping from your previous guide to this one for updating to 10.13.6
I'm doing a clean installation and I got a kernel panic at step D.4.7 when I reboot for the 1st time during the installation.
When I boot from the USB and I select the current disk who I'm installing the os, after a few lines, it's frozen with the message 'Please go to https://panic.apple.com".
I tried to change disk installation, change APFS to HFS, in any case I can't go further.
I also tried to enable the "_xcpm_core_scope Kernel patch" in case I've doing any mistake during the bios patch, but no luck.

Do you have any idea ?

Configuration :

- ASUS Sabertooth X99
- i7 6950X
- 2x 1080
- 64 GB RAM


Thanks. ;)

My friend, it is difficult to answer or to give you any advice based on the information you provide above. At first place, it would be useful to upload your EFI-Folder and a complete set of screenshots of your actual BIOS settings.

I also do not really understand at which step the MacOS Installation fails in your case. Apparently, you can successfully boot with the EFI-Folder and the respective macOS installer on your macOS Flash drive installer, and successfully complete the initial macOS installation procedure, which basically consists in the creation of the macOS installer partition on your future system drive? Now after reboot, you boot again with the EFI-Folder on your macOS USB flash drive installer but this time you correctly start from the "Install macOS .." partition on your system disk apparent within the Clover boot menu?

Are you sure that you are using the EFI-Folder on your macOS USB flash drive installer for booting your system also in this second step of the macOS installation or do you boot with the EFI-partition on your system disk instead? Is there at all an EFI-partition and EFi-Folder on your system disk and is the latter identical with the one on your macOS USB flash drive installer?

Yes I have a copied the "EFI" folder from my USB Stick to the EFI Part on the target SSD. (I've formated it before with my macbook pro and a SATA adaptator)
I've checked my bios settings, put the USB Stick, boot from it, reach the OSX installer. I've selected the SSD previously formated to HFS, and start the installation.
After 4 mins, reboot happens and that's after it's screw up, when after the reboot, I'm booting from the USB stick and select the SSD from Clover, I got a kernel panic. I've attached bios settings and EFI folder.

I cannot find any EFI-Folder in your attachment

BIOS Screenshots incomplete... anyway, apply following changes:

IO Overclock Tuner -> XMP
Asus MultiCore Enhancement -> Auto
CPU Core Ratio -> SyncAllCores
DRAM Frequency -> set your DRAM Frequency
Above 4G Decoding -> Enabled
CPU SVID -> Enabled

Please upload your EFI-Folder!

Did you patch your motherboard BIOS Firmware? Do you have locked or unlocked MSR register?
