I had to disable whatevergreen to fix the boot loop.

Thank you. That fixed it!

I installed Tahoe (upgrade of sequoia, not a fresh install) on an Asrock B660 machine (yes I know it’s Intel). It installed fine and boots into Tahoe, but all usb ports are dead. The machine dual boots windows, so I tried usbtoolbox in windows to map the usb ports. I put usbtoolbox.kext and...

I'm trying to install Tahoe beta 2 onto an Asus B850i with a Ryzen 9900X. It went through the install process ok, but now is in a boot loop where it never makes it to the desktop. I've attached my EFI and some debug info. Any help greatly appreciated.

Please post your EFI. Thank you.

I tried installing Tahoe on my Mac Pro 2019, which is supposedly supported by Tahoe, but I got this error message. Any insight out there?

Verbose output went on for about an hour followed by kernel panic.

Well, I am getting closer. I started with my EFI for an ASUS B850I with a Ryzen 9 9900X and did the following: 1. Upgraded to Opencore 1.0.5. 2. Replaced the kexts with the updated ones posted above. 3. Replaced the patches with the new beta patches on GitHub. 4. Ensured I was using a...

Is Opencore 1.0.5 required?

Here are some screen shots of the screen after freezing. I’ve checked bios settings multiple times. They’re the same as on my Strix B850-I.

Same result every time. I’m stumped, never encountered this before. There seems to be other folks having the same issue but I can’t find a consistent solution. Thanks for your effort.

I am using an EFI that successfully boots Sequoia on a ASUS Strix B850-I with a Ryzen 9950X. I am trying to use the same EFI on an Asus TUF B850M with a Ryzen 9900X. I have edited the kernel patches for a 12 core CPU vs 16 cores. However, it abruptly stops during boot. I have verified that I...

Same result. I've attached the last few seconds of the verbose output. When the screen goes black, it reboots.

I had given up on this for a few weeks. Has anyone had success with a Ryzen 9900X? It just goes into a continuous boot loop.

I tried this. When I purposely put it to sleep, the monitor went dark, but all the fans and lights stayed on, so I don't think it fully went to sleep. When I hit the space bar, the monitor came back on.

I've got two Asus B650E-F board, BIOS 2613, same BIOS settings, same graphics card. One has a Ryzen 9700 and boots Sequoia just fine. The other has a Ryzen 9900X that has been very problematic. @Shanee was very helpful in making modifications to Open Core to solve a problem with core counts...

I don’t let mine go to sleep, so I don’t know.

So you believe it’s an issue with my efi folder?

I’ll give this one a try. The output from verbose mode flys by fast. I don’t know how to isolate the last line of output before the screen goes blank and it reboots. I’m using two different machines for the 9700x and 9900x. Same motherboard model, bios version and settings, and same video card...

Perhaps we’ll have better luck with the 9900X3D
