Cannot Update System Definition from 14,2

[Krow01]

Hey all,

I'm currently on Mojave, prepping to update to Big Sur. Got all my ducks in a row in terms of updating firmware, patching ACPI after firmware update, and making sure all my apps are 64bit compatible. Now the hard part.

I have tried multiple system definitions from iMac Pro 1,1 to iMac 18,1 18,2 18,3 19,1 19,2. All of these clear the verbose boot stage but then the monitor shuts off as if its no longer getting a signal from the GPU (AMD RX580). If I go back to 14,2 then everything is fine again and no issues.

Any ideas of what could be causing this? Any clues surrounding a fix? config.plist attached in case it's instructive.

Your Clover version needs updating - Missing Quirks section.

Safest/easiest way to update it without causing issues? Seems like every time I update via standalone I bork something.

In the newer versions of Clover the folder structure has changed, make sure that you have all of your drivers in the new location. /EFI/CLOVER/drivers/UEFI.

There is also the addition of a Quirks section in the config.plist which means that you cannot just take your old config.plist and use it with newer versions of Clover.

Rather than learning the newer variations of Clover which incorporate elements of the OpenCore boot loader, it would be better to switch to OpenCore now which is better documented/supported.

If you want to update Clover safely then do it on USB leaving your current installation intact.

How to Update Clover v2.4k r4xxx to v2.5k r5xxx (v2.4k r4972 to v2.5 r5018 example)

I really like to update Clover every time I update to a new version of Mac OS to help prevent issues. For 10.14.6 however, the Clover update would not work. I eventually found out that there are changes in Clover v2.5k that do not allow simple updating from v2.4k – detailed in a post by Slice...

Yikes okay. Will switching to OpenCore require a fresh install or is it relatively safe to switch with an existing setup?

It's a boot loader so no need to reinstall the OS.

Do it on a USB flash drive and then nothing changes on your hard drive.
When it is running smoothly you can install to the hard drive.
