DISCLAIMER - Pay attention! (Familiarity with ACPI is required) Patching a DSDT is risky. Do only if you know risks and how to recover it if something goes wrong! Hi everyone, with the release of new bios for am5 platforms which allow pre-support for 8000 series CPUs we came across a bug that no longer started macos. @fabiosun and I started by trying these new bios without success in starting macos, until I had the idea of injecting the old dsdt of the previous bios with true on the RebaseRegions quirks. Subsequently I dedicated myself to patching new bios and removing new conditions that were added : removing the entire CPVS section generates 30 errors in my case : I started to correct these errors by removing conditions for loading devices or _PRW methods : there are so many that it removes the if... string with the bracket { and at the end of the scope also remove a bracket } so as not to generate other errors. and I also removed this whole part: Attached in this post original dsdt of new asus b650e-i's bios f and the patched one (asus b650e-i) Original - DSDT.aml.zip --------------------------- (asus b650e-i) Patched - DSDT.aml.zip --------------------------- (asus x670e gene) Patched - DSDT.aml.zip --------------------------- (asus x670e hero) Patched - DSDT.aml.zip --------------------------- (MSI X670e Pro Carbon) DSDT.aml.zip --------------------------- (Asus ROG B650E-F) DSDT.aml.zip --------------------------- (ASUS ROG STRIX X670E-F GAMING WIFI) DSDT.aml.zip --------------------------- (ASUS X670E-I) DSDT.aml.zip ----------------------------

@fabiosun @Lorys89 What a crazy thing! I follow a model I created, which is this one: https://github.com/luchina-gabriel/BASE-EFI-AMD-RYZEN-THREADRIPPER I always keep it updated (Opencore, Kexts, Kernel Patches, etc.) month to month... I've been trying everything for more than 7 hours and haven't been able to boot the installer. With its EFI I made some small adjustments and it booted perfectly. I went crazy! I took this model of mine, inserted its DSDT and I just enabled RebaseRegions for her, and it worked perfectly! Summary of everything: This damn BIOS 1709 LOL LOL LOL! I'm going to follow my script here, to see if everything is working, and I'll share the results with you later. Thanks a lot for the help! 😄 😄 😄 [offtopic] My Italian passport should be out in a year! When I go to Italy, I'll have to buy you a beer! 🙂

Other users who also have the same issue please do dump your ACPI tables and post it here. Thanks!

I tested with the new DSDT for the X670E Hero, and it worked with BIOS 1709. Now I'm testing with the previous BIOS and without DSDT to see if it works too. I had the misfortune of setting up the setup, updating the BIOS and getting this problem with the 1709. LOL! Thank you very much for all of your help.

A user with x670e gene just upgraded to 1709 without any issues.

I've downloaded it for safekeeping. When the new Ryzen 8000 processors hit the market early next year, I will very likely purchase one. Updating BIOS on my motherboard has been a relatively painful experience, so I do this only when necessary.

@Lorys89 Nice work and thanks for supporting the X670E Gene!!

Hey @fabiosun and @Lorys89, Thank you very much for the guidance from DSDT and EFI. I'm going to test it now, I'm just modifying it to remove the BCM because I'm initially going with the Ventura. I'll be back to give feedback! Regarding the videos, I can definitely give you a mention, thank you very much! 🙂

@luchinaadded in OP Pay attention... it is done for using togheter OCLP (Opencore Legacy patcher i use for Broadco WIFI in Sonoma) so.. it has some modify Secure Boot Model Sip Amfipass kext and some patched kext for wifi You can easily disable all this stuff if you do not use OCLP a mention in your beautiful videos of our forum would be very welcome in case you find this EFI useful 🙂 🙂 Uma menção em seus belos vídeos em nosso fórum seria muito bem-vinda caso você ache esse EFI útil 🙂 🙂

No @luchina @Lorys89 is writing a how to do so I didn’t update his modified dsdt

Si si puoi usare amdpowergadget oppure anche dei kext che sono stati adattati da @Lorys89 io uso questi ultimi insieme ad hwsensorSMC

Mulettin proprio beliN!

Secondo me hai troppa roba: non avevo mai visto così tanti ssdt insieme. Ma anche a livello kext non scherzi.
