[Success] b1's "Mac Mini Killer" with macOS Mojave: i7-8700 | Gigabyte Z370N | RX560 | 16GB RAM

Hello,

There are times when updating/upgrading does not work "just like that".
A plan must always be made ( make backups/make notes/take photos/find important BIOS settings/gather files/read documentation/look for what others said/done, etc)
So, you had a bootable/working system running Monterey OS ... and took a brave decision.

Before anything else, can we assume that the original EFI folder ( from the working Monterey, without any editing) was actually saved?

Grabbing random files/directories for inspecting/learning may be a useful activity.
Accidental use of files/folders can be undesirable/dangerous.

So, you confirm that you have a working/untouched EFI folder ( existing before update)

So what were you doing ? It seems like you start the upgrade from Monterey to Ventura using the random EFI ( not the original one )... and it crashed.


Did you really expect it to go without a hitch?


Let's see how we can help you ..

I had a look to the attached EFI folder. It seems to be about 2 years old.
Is this your original EFI ( the one working with Monterey ) ?
If so, preparing a bootable USB stick with Monterey and using this (original) EFI folder should be the way to go
and get a new installation.

It could be possible to upgrade your EFI to the latest components and (possibly) have a more up-to-date system.

My recommendation is to go on safer path ( it is easy if you have access to a running Mac/Hack) :

- download Monterey from Apple site
- format a USB stick (16+ GB)
- "transfer" the installer on the USB stick
- Mount the EFI partition of the stick
- copy your original EFI on this partition
- unmount/eject the USB stick
- verify/edit the BIOS settings of the target PC
- start the new installation on the target PC

It should work.


Well.. i3-8100 is not Ivy Bridge. Rather Coffee Lake ( 8th gen Intel CPU )
RX 560 is a fine card .... it can be used with many OSes.
The Broadcom WiFi should work very well with Monterey.

I know, this time it could be a more appropriate EFI folder ( but still a "random" one ).
Not the way to go. Not even for Ventura.

We must solve this problem : re-install ( may be on a spare drive, to preserve important data on the original disk) Monterey OS using a genuine/original EFI folder.

What's your answer ?

No ! Do not do it ! ( Do you have a plan ?)

Cheers.

Hi - thanks for this. I took a backup of the working EFI and it no longer works. I will try Petros efi below…

Where do I find the Board Serial Number on config.plist?

Also, do you have a post with your bios setting?

For your configuration I would choose imac19.2

te ha funcionado mi efi?
 
If you click to the right of the "check coverage" box you will see a drop-down with the mac settings and when you choose one it will automatically give you the numbers
then you hit save

@petro - thank you. I got it to boot and finish the installation to Ventura (Yay!). The display port for the RX560 doesn't work. I suspect its the bios settings. Can you share what yours?

I have it configured like this
you should read dortania's guide

Hey, Petro! Yet again thanks for keeping this thread alive! I finally got myself WD SN750 NVME ssd and thinking to do a fresh install of Ventura 13.6.

I was wondering whether I can skip all this learning with Open Core by just pasting my serial/mlb etc and use your EFI. Since I'm still using Clover and Big Sur 11.6. Our config is basically the same except the GPU, so i suppose in my case I'd only need to add "agdpmod=pikera" and use my usbport.kext that I made earlier for Big Sur?

Also, what do you use for config.plist editing? I find OCAT is very user friendly and I've heard that Open Core Configurator isn't the best one to use these days.
