Well, it got further but went into a boot loop. I erased the drive tried to install from scratch still getting boot loop. UPDATE: I updated the EFI on my Ryzen 9700 with this and it booted fine.

Here ya go.

Yes, from the attachment on post 192 of this thread.

Here is the debug log and SysReport.

Same result. Thank you for your work. I'll keep testing as long as you're willing to work towards a solution.

I gave this a try on my Asus ROG B650E-F, BIOS 2613. Same result. I have attached my EFI and debug output.

The 9900X or 9950X?

Same result.

I tried putting the Ryzen 9700 in this machine, revised the core count in the efi on the usb and it booted just fine. I believe the problem is specific to the 9900x. I’m giving up for now.

This was unsuccessful.

I’m using 0C for the twelve core. I just tried the new AMD patches. Still no success🤬.

I am using aa6f402 and still having this problem. This exact same (except for core count) EFI works on the 9700 with the same motherboard so I am really stumped.

I’ve been following this thread closely since I bought Ryzen 9700, 9900, and 9950. With the help of this forum, I have managed to successfully boot MacOS Sequoia on the 9700 and 9950. However, I have not been successful on the 9900. I installed it on an Asus Strix B650E-F (BIOS 3024) using the...

I have several Hacintoshes using the Sapphire Rx 6600 graphics card. They all worked fine until I upgraded to the Sequoia beta. Then black screen after the verbose boot. Both AMD and Intel machines. I tried replacing each sapphire card with an XFX RX 6600 out of a Windows machine and all them...

This machine is setup for dual boot and windows runs fine on BIOS 2613 which was the first version that supported 9000 series.

I tried downgrading the BIOS to 2613 since that was the version the patched DSDT is based on. Still no joy. I tried replacing the Ryzen 97000 with a Ryzen 7700 and it booted right up into Sequoia 15 beta 6 with no issues. Tried several successful reboots. Put the 9700 back in and I get the...

ACPI is way beyond my knowledge. I’m an amateur compared to you guys. I tried disabling the patched DSDT and tried the DSDT from the link for my board. Same result. I posted screen shots for my BIOS if that helps. Thank you.

Yes. I included the patched DSDT, but I am Unsure if it works with the latest BIOS (3024 I believe).

I installed a Ryzen 9700 into a Asus Strix B650E- F (latest BIOS) that was successfully booting Sequoia Beta 4. Using latest kexts, patches, etc. I was not really expecting it to boot on the first try and I was right. See screen shot attached. Has anyone else tried to Hackintosh a Ryzen 9000...

I have disabled SIP on my Sequoia beta 5 machine and tried this. It is definitely not mounting the EFI partition. Is there something else I need to do to make this work?
