MP 1,1-5,1 11.6 Upgrade from 11.2.3

[twiggs4625]

I've spent all day getting opencore to work with my 5,1 and was able to get a fresh copy of 11.2.3 working well.

I then decided to test the upgrade to 11.6 from the software update and it seemed to hang on the update when booting. I have attached a screenshot.

Should I reformat and go back to 11.2.3? I guess I just like being on the bleeding edge.

Specs:

Dual 3.33
128GB Ram
RX580
PCIe USB 3.1 expansion card
1TB Samsung 860 SSD (boot)
1TB WD Black NVMe PCIe (scratch)

Side note: I was using a USB to boot while setting up 11.2.3... prior to rebooting from the update to 11.6 I installed the OpenCore EFI files to the internal SSD so it would boot on its own with the GUI version of OpenCore (most recent as of posting this.)

I was on the 144.000.000 bootrom

I know before I rebooted it stated something like 9999.9999.9999.9999 which I thought was odd.

Any feedback is appreciated. Thank you all that make this forum a great place.

I have a my Samsung SSD upgraded to 11.6 - it appears I need to add this fix to this patches EFI drive...

strange thing is this. I have the old internal drive that I can boot from which is on 10.13.6...

If I try to boot with the 10.13.6 drive and my SSD drive at the same time and hold Option to try and boot from it says this Mac OS is not supported.

however if I take my SSD out it will boot fine, problem is the SSD drive doesn't appear to be hot pluggable and I cannot access the EFI to edit the config.plist

Any ideas? Thanks for any further advice to help me get this machine to boot.

I got it! Needed an external SSD adapater and was able to write the new opencore to the EFI of the 11.6 boot device while back in OS 10.13

I learned also that the GUI version of opencore didn't install the latebloom data like the TUI did... not sure why that is.

anyways... I'm backup and running. Thank you.
