Dear all, My EFI works perfectly with macOS versions 13 through 15. However, when I try to boot macOS 26 Tahoe beta 3 to 5, it gets stuck on this screen and enters a reboot loop. Below are my hardware specifications and config. cpu: amd 9900x mb: asus tuf-b850 plus wifi gpu: rx570 m2 nvme 1tb...

Hi, I have successfully run macOS Sequoia 15.5 on my hardware setup: AMD Ryzen 9 9900X + ASUS B850 + AMD RX570. I’d like to go a step further — is there a chance to enable or use the integrated GPU (iGPU) of the AMD Ryzen 9 9900X for Sequoia or Sonoma? I’m also curious to know if there are any...

hi @fabiosun , Although I am currently using a USB Ethernet connection, I would like to know if it is possible to get the built-in network card RTL8125 to work properly. I have tried loading LucyRTL8125Ethernet.kext, but it is not recognized, as shown in the attached image. Currently, this is...

Hi, I have a server-grade PCIe network card, the Intel X710 DA4 On my Intel-based Hackintosh running macOS 15 Sequoia, I was able to enable VT-d, use SSDT-DMAR and AppleVTD, and successfully get the X710 working After doing some research, I understand that the AMD platform does not have a DMAR...

@fabiosun Thanks for the reminder! I later switched to Shaneee's version of PAT and noticed a significant boost in game performance. For example, a game that originally ran at only 30 FPS can now reach 55–60 FPS with Shanne's PAT. It's truly amazing. I love AMD, and I love all of you! By the...

I found the issue — when I uninstall iStat Menus first and then run the OCLP patch, everything works fine.

Ｈi, On macOS Sonoma 14.7.5 with OCLP 2.3.2, after applying the Post-Install Root Patch and rebooting, my system crashes or freezes after login — likely due to my Wi-Fi card (BCM943602CDP). I've included screenshots of my Kexts and config.plist, as well as a zipped version of the config file...

I have found the audio soluation here: https://github.com/AMD-OSX/AMD_Vanilla?tab=readme-ov-file#information-on-the-fix-pat-patch (y) ;)

I'm having an audio issue, but I'm not sure where to start looking The audio coming from the DisplayPort source of RX 560/570 has a lot of noise which connceted directly to DP in of the Monitor.

@fabiosun On my b850 i set DisableVariableWrite to True and left MMIOWhiteList part all to false This allowed me to complete the macOS 13–15 installation successfully despite some minor hiccups. Thanks A LOT!! by the way I will try the second area of MMIO that was metioned

@Katanoko1221 dont you have fast boot & secure boot? from your MMIO part of opencore debug log: 03:283 00:002 OCABC: MMIO devirt start 03:285 00:002 OCABC: MMIO devirt 0xE0000000 (0x10000 pages, 0x800000000000100D) skip 0 03:287 00:002 OCABC: MMIO devirt 0xF7000000 (0x7E00 pages...

@Shaneee For me, I'm using OC debug which is from post#86 mainly

@fabiosun If I enabled the 0x880000000 in Booter/MmioWhitelist of config.plist and reboot. It will be stuck at a reboot loop when I hit macOS Sequoia Installer. I was surprised to find that when I hit macOS Ventura Installer, the process was relatively smooth. Finally I got the Login screen...

I think we got a further step, after adding the acpi and mmio patches. Yes!! Yes!! I could get into macOS Sequoia installer. but I am now stuck at OC menu. It has been running reboot inifinly when I hit macOS Installer at OC menu and here is the lastest log. Thanks anyway.

Sorry! I misunderstanded, here is mmio area: 09:268 00:004 OCABC: MMIO devirt start 09:273 00:004 OCABC: MMIO devirt 0xE0000000 (0x10000 pages, 0x800000000000100D) skip 0 09:278 00:005 OCABC: MMIO devirt 0xF7000000 (0x7E00 pages, 0x800000000000100D) skip 0 09:282 00:004 OCABC: MMIO devirt...
