The debug kext made my R5E10 (X99 based) mobo bootable with Monterey 12.1. Thanks for the post!

Got an used Rampage V Edition 10 with cheap price and replaced old Sabertooth X99 with it. Also, replaced GTX Titan Black with Radeon RX 6800 XT. Installed Big Sur from scratch. Now Big Sur 11.5.2 with OC 0.7.2 is working fine. Of course, I have applied both "MSR 0xE2" and "NVRAM white list"...

I have tried various settings, but no luck at all. So, switched to USB audio for now...

Attached the EFI.zip which I used during Big Sur Installation. I have removed the "Cpuid1Data" under Kernel section and whole entry under SMBIOS section from the "config.plist". So please adjust them to fit your system configuration. But before moving forward, I would recommend you to verify...

Hi, Probably, I was hitting this issue (Please refer to bottom of that page). Seems that the native NVRAM on my SABERTOOTH X99 was not compatible with macOS 11. So that I added the NVRAM whitelist patch too using the CodeRush's UEFI patch tool described in KGP Guide. If you have an interest...

I had fought with Big Sur installation for past three weeks without success because it keep failing at stage 2 installation. So, I spent a lot of time to research my issue and finally reached to a solution. Now macOS 11.0.1 (20B50) is up and running on my rig (SABERTOOTH X99). Followings are...

If you are an X99 user, a kernel patch is required. Please refer to this.

Good to hear that. Special thanks to PMHeart !

Had exact the same problem on my rig. In my case, adding below kernel patch could solve the issue. <dict> <key>Comment</key> <string>_xcpm_pkg_scope_msrs © PMHeart 10.14.5</string> <key>Disabled</key> <false/>...

Hi RehabMan, Thans a million! After putting FakeSMC.kext and replacing config.plist with nuc6_sc, I was able to reach to the installer... Thanks again for your quick help! +++ How stupid I am. Sigh... +++

Hi RehabMan, Thank you so much for your reply! I downloaded macOS from the App Store. I have created two Install USB media. One is on my X79 hacked-build (pls refer my profile) and the other is on my MacBookPro (genuine). But both did not work… I have tried all four USB ports, but got the...

Model : NUC6i5SYK (BIOS 0054) Memory : 32GB (16GB x2) Storage : Samsung 950 PRO M.2 MZ-V5P512B/IT (NVMe 1.1) macOS : 10.12.1 Clover : V2.3-r3949 I am trying to install Sierra on my NUC6i5SYK with following this guide for past 7 days. However, I still cannot reach to the installer. It always get...

I have exact the same problem. Not 100% sure, but probably, we need to modify USB definitions in DSDT. https://www.tonymacx86.com/threads/x79-usb-2-0-in-el-capitan-10-11.174654/ My installation has not been completed due to another issue, but at least, I was able to reach the Sierra Installer...

Just F.Y.I. My Sapphire Ultimate HD7750 start working again on Yosemite 10.10.4. Please refer to the POST#12 above. It seems that we need to change the "CAIL_DisableDrmdmaPowerGating" from 1 to 0 on 10.10.4. Thanks a million to JayBIOS2 and luckascesium !

Having exact the same issue. Tried the same with using another machine with freshly downloaded the 10.8.4 app and got the same result... Correction: Not sure how long time it did take (at least, more than 90 minutes). But it completed successfully.

Hi Nano07, Thanks a million!

Hello, If possible, could you please share the DSDT.aml for D975XBX2 here again? Because above site seems not accepting new user registration, I cannot login to download the file... Thanks and regards, jin
