Probably simplest to get the latest .zipfile (Snoopy69's Sonoma zipfile) and use that (with the latest SMBIOS, which will let you run 14.3). That will require new serials and such, so wise to sign out of any and all Apple accounts before doing all of this, and become re-read the documented...

...right, that's what I am asking. Can you help with my questions?

Just a question: are the original BIOS settings (in post #1) still accurate? If we update to the current, latest 3005, I think some options have changed; is there wisdom in posting a super quick vLatest summary with 3005 so everyone's on exactly the same page?

If I am understanding correctly: 1. Get the normal PC / Snoopy69 EFI and modify it to suit with SMBIOS, serials, etc. as per the norm for the past few years. Overall recommendation is (I'm asking here...) iMacPro1.1 now, or MacPro7,1? I think I've seen both. 2. Then, once that's all...

@pixelmambo - Just a quick note to let you know I'm running BIOS 3004 and it works great...

Or one can just use Intel WiFi (common on newer boards) or can just skip wifi altogether, for a simpler Sonoma experience.

Pls be aware that the simple act of opening, then saving, that config.plist with OCAT fixes that error in Validate. OCAT just handles it, and it does a host of other cool stuff too (like effortless upgrades to later OC releases), automagically. Think about grabbing it. Always work from a...

Check BIOS settings, aligned with the first page, perhaps?

Sorry to ask the blindly obvious to Davinci Pro pro, but ... if you jump on a Mac and run those same workstreams, you _do_ get 100% CPU and 100% GPU? Edit: Newbie on dvp; just reading some forums earlier today to see what's accellerated.

Ultimately the solution: 1. DP: Must be lower case. In all but my last test round it was, but for the start of the last test round when we had the solution, I made it uppercase, delaying the solution. 2. BRG0 File Setup: Download the OpenCore default, and simply change the mentions of...

Alas, but with the attached brg0, no change. :(. Any other ideas? I'm working from a USB stick (in case of error, fallback to known ...acceptable... SSD EFI). I have the config.plist changes in DP section that I used with previous setup: and ..which seem fine... And I have the ACPI...

Reviving an old thread, my i5-12400F and Asrock B660M-HDV went (poof) after a PSU issue. PSU was replaced under warranty; no such luck for the MB and CPU. Now I'm trying to put the 6900XTXH into the older i7-8700 / Asus Z370-ITX (BIOS 3005). I can boot into MacOS without doing anything; the...

You've not updated the associated KEXTs that go with this OC release. Can you check this?

...or, a quick reminder, to upgrade your own setup in place: This is a quick guide to inform newbies how to update OpenCore using OCAT. Keep in mind: You should update and test OpenCore on a backup USB stick, so that if something bad happens, your main SSD’s OpenCore will still be bootable. Or...

This is a quick guide to inform newbies how to update OpenCore using OCAT. Keep in mind: You should update and test OpenCore on a backup USB stick, so that if something bad happens, your main SSD’s OpenCore will still be bootable. Or keep a bootable USB stick as a backup; this write up assumes...

I was just focused on “How to update OpenCore from release to release” rather than anything to do directly with MacOS.

Same - thanks for the amazing work! There might be value in a quick document on how best to update OpenCore using the OCAT utility, so that people could then become familiar with an easy and straightforward method to upgrade to the latest, as surely Sonoma fixes and more general bug fixes will...

Is your EFI zip posted somewhere, so we could have a look and confirm a few things?

Why run a previous OS?

Latest BIOS on the Z370N? 99dC is pretty hot for a 9th gen Intel CPU. Is there correlation between crashing/reboots and the upper end of that temp? Does it crash in Windows if you run CPU stress tests?
