MSI PRO Z690 A DDR4 + i7-12700K + AMD RX 580

Hi Guys this is my first hackintosh attempt!

I trying to install Big Sur since that's the latest OS supporting the GT710 GPU

Luckily I found this post with a very similar build, so I took off with the EFI of @NorthAmTransAm, made the changes suggested by @danny2305 for enabling onboard wifi and BT support, but I'm stuck at booting the installer.

My error is the same as posted here:

volume macOS Base System is read-only

Hi guys, I'm new here. So I spent 3 days trying to install Big Sur (Catalina is installed now) Not sure what is certainly stops the install, but I think it caused by "read-only" error. - HID: legacy shim 2 - Generation from SMC report as 2 - macOS Base System is read-only - Loweset level disk...

I have the Samsung 980 pro NVMe SSD

What am I missing?

Hey friends and followers of this build. Sorry for the disappearance here, I left for a two month tour (music stuff) and caught covid the day I got home. I'm moving to a new house in a week as well but will hopefully be back to participating in all this fun stuff September!

What did I miss???

Good to see you're back! Could you perhaps take a look at my first hackintosh attempt?. I started off with your EFI and made a post of my fail here:

Stuck on installation script errors [MSI MAG Z690 TOMAHAWK WIFI, i7-12700F]

Hi, I'm trying to install Big Sur (11.6.8), and getting desperate about making it work... I followed this guide: https://www.tonymacx86.com/threads/msi-pro-z690-a-ddr4-i7-12700k-amd-rx-580.319149/ I'm stuck during the USB installer on with error "lowest level disk is not mounted" and...

@NorthAmTransAm, hello. Would you help me?
Sometimes ago I got on my MSI Pro Z690-A DDR4 very strange bug: when I'm trying to load recovery or installation from flash, I can see gray screen with mouse cursor only. Maybe BIOS update or OC update led to this result.
The macOS is loading on this configuration wonderful, but I can't install 'clear' system.
I tried a lot of different EFIs (including your from this theme) - the same.
Something wrong in BIOS settings, I guess.
Would you show me screenshots from your BIOS settings?

I can't quite get to the BIOS at the moment but besides the basics in Post#1 there's hardly anything to do except turn off Thunderbolt (unless using it). I will say, I don't love the BIOS on this board. Every other restart and you get a slow boot into OC and no keyboard control and updating BIOS was quirky at best. I suggest doing a full shut down and unplug before heading into recovery.

Sure, You're right, BIOS on this board written under heavy d-s.
Thunderbolt is turned off. I'll try to unplug before recovery, thanks.

@NorthAmTransAm, unfortunately, unplugging doesn't help to me. What BIOS release are you using?

 

[sonny362]

OMG! I feel like an idiot.
Clearing NVRAM just before loading Recovery or Installation solved my trouble.

I can't believe I didn't suggest that. Glad you're up and running!

@NorthAmTransAm, many thanks for your hard job !
The motherboard of my hackintosh crashed last week after 8 years of good service. I already own an RX580, so I bought the same motherboard as yours, and a i5-12400 cpu.
I've updated the BIOS to the same version as yours, used your EFI folder (OC 0.8.0), disabled the Airportbrcmfixup kext, generated a serial number and voila ! Mac OS Monterey is working flawlessly.
My wifi card is OK, and my Bluetooth dongle, too.
Just a little problem with the I255-V Ethernet. Link is OK, but macOS doesn't receive address form the DHCP. However, it's working under Windows 10, so it's not a hardware problem.
I read in this forum that the problem can be solved with forcing duplex and speed. I confirm this trick is working !
I saved a lot of time with your work ! Thanks again.
