I also had some with OCLP 0.2.4 and then I upgraded to OCLP 0.2.5 and redid the patcher in that version, then it stopped. Now everything is fine.

This sounds promising but, 0.2.5? In the github page the 0.2.4 is the latest version. --edited-- Never mind, I've just saw the Nightly builds.

Also (just to clarify this to be sure) when you say "redid the patcher", you mean that you pressed 1 to build opencore and after that, you pressed 2 to install the patcher to the boot drive. Not the 3rd option with the Post-install Volume Patch, right?

I haven't done it, but I imagine you just follow the instructions on the OCLP Github to create an OCLP installer, boot to it and install the operating system over the top of your existing installation (when selecting which disk to install on, select your current Big Sur drive). Then complete any necessary post install tasks (all detailed on Github). Ensure data is backed up in case anything goes wrong. If you encounter issues, nuke the drive, perform a fresh install then restore data from the backup.

BTW, OCLP is awesome. I only found out about it this week and my 2009 MacBook Pro is working almost flawlessly on 11.6 following an OTA update - I expected it to be stuck on Catalina for the rest of its life and couldn't get the latest security update to install. Having OTA updates is revolutionary compared to the older patchers and saved me so much time compared to the old ways of updating. It's also probably your best bet at getting Monterey running, so it might be worth putting the work in to migrate.

Thanks ! So I decided to install with TUI, OCLP on my existing installation made with Patched-Sur. It worked perfectly with the online help. Subsequently I had to uninstall Patched-Sur because it was trying to do its job to notify me of updates, but there was nothing left in Vram ... I am updating 11.6 via the software update, everything seems to be going well. See you for new adventures and thank you for the help! (2 iMac Late 2013 21 & 27 & a MacMini Late 2012 )

It Is right. Not the 3rd option, only 1 and 2.
 
iMac 12,2 on OS 11.6
GTX765M
OCLP 0.1.5 (on SSD)

Recently decided to update OCLP to 0.2.4, and now mac won't reboot (stuck on boot screen, progress bar 40%)
-Cleared NVRAM PRAM, no avail.
-Cannot boot into Safe Mode (command no longer recognized)
-In Recovery Mode, diskcheck returns no errors
-in Recovery Mode, TimeMachine prompts me to install OS first then move data from backups - but cannot re-install OS since Apple latest available OS download (11.5.5) is lower than the installed one (11.6)
-Tried booting from USB with OCLP 0.2.4 and reinstall O) (11.5.50, but OS installation fails to load (stuck on boot screen, progress bar 15%)
-Tried booting from USB (OCLP 0.2.4) and then chose the normal SSD OS (11.6) for startup, also hangs
-And since yesterday, Recovery Mode defaults back to native Mac original install (High Sierra), which does not recognize any TM backups, and when trying to install High Sierra on available Mac drive, I get installation error -03

Any ideas on how to solve this are most welcome, thanks (besides wiping out everything and starting from scratch 🙄)

This is just an assumption:

Try to disable SecureBootModel on your OCLP using the patcher settings. You should not use High Sierra and Big Sur in parallel, starting High Sierra corrupts the Big Sur preboot partition (there is an issue on GitHub describing it and a fix in detail).

BTW:
The 11.6 full installer is out, now.
And the latest versions of OCLP would disable SecureBootModel by default because it is broken on Monterey as well. I assume 0.2.4 did not because the old existing 0.1.5 had it enabled and there is some logic to preserver user changes.

Many thanks for that, Ausdauersportler. SBM is disabled.

I have since managed to reboot via USB using OCLP 0.2.4 and reinstalling OS 11.6 (as per link above from viettanium - thanks!)

So now this happens:

- when running OCLP 0.2.4 I cannot install post-installation patches, keep getting the "disable AMFI" error message (tried sudo nvram boot-args="-no_compat_check amfi_get_out_of_my_way=1” but that didn't do anything)

- when installing the OCLP 0.2.4 on my hard drive, the boot fails again as before - stuck on black boot screen with 40% progress bar

- when booting from OCLP 0.2.4 on USB drive, boot succeeds and system (seems to) work normally - except now I have no more internet connection (Wifi & Ethernet) on the Mac

Thanks for any suggestions.

You do not need any post-installation with your metal GPU.

That is why the AMFI has not been disabled by the patcher. I am not sure what you have done in the past with your iMac? Are you sure to have the very same OC config on USB and internal SSD?

Ah. Well that's news to me. Didn't know but seems obvious now, thank you.

I have re-built & installed the OC on my SSD using the same file as the one used on the USB drive. Any leftovers stuck from previous OC versions on my SSD, maybe....?

Any leads re. Wifi/Ethernet issues?

Thanks

There are no known WiFi or Ethernet issues with Big Sur on your system.

Just start over!! And read the GitHub OCLP docs.

In rare cases (mostly when switching/changing the OC config) the injection or activation of the WiFi, Ethernet or Sound extensions may fail. After a NVRAM reset this disappears normally.

It is not worth the time to find the mistake.
 
I just started following this thread as well as the 2011 iMac GPU and CPU threads. I have a mid-2011 iMac 27 (iMac12,2) and have maxed the RAM and added an SSD. I have a Xeon on the way that looks like it will be fun to play with, and just got the same Broadcom WiFi card that Ausdauersportler used in his 27" 2011. I look forward to getting a replacement GPU to get this machine onto a more modern version of the OS. Big Sur is my preference, of course, but Catalina would be almost as good.

Here's to the many hours of reading I have ahead of me. Lots to learn. Please forgive any newby questions I will likely ask. I'm trying to learn a lot in a short time, so cut me some slack; I'm a classical musician and not a computer guy. HAHAHA!!!

Cheers, all!

Updated from OCLP-11.52 using the 11.6 full installer (12.43GB InstallAssistant.pkg); opted to use this rather than the OTA incremental update just because I like using the complete "combo" updater every so often. It took less than 1 hour. All is working well, so far.

Here's my device info:
MacBookPro Retina, mid-2012, 2.6GHz Quad-Core i7, 10,1; Broadcom BCM94360csax; Big Sur 11.6 (20G165) OCLP_TUI_0.2.4

just a thank you post to the developers.
back in July, I was running OCLP 0.2.3 and 11.4 on my trusty Mac Pro.
11.5 was released and thought to do an upgrade. then hit the crashing on boot, so I retired the Mac Pro (temporarily).
today, I downloaded OCLP 0.2.5 TUI (nightly build), updated my trusty OCLP 0.1.6 USB bootable to 0.2.5, then booted the Mac Pro off the USB EFI and chose my internal SSD macOS (11.5 upgraded) drive.
first boot, was back up and running. installed 0.2.5 efi onto my internal SSD, reboot and now working off my Mac Pro again 🙂
fingers crossed for a successful upgrade to 11.6

thanks again to the developers of OCLP and continued updates 👍

@hvds : Did you already succesfully update your OCLP 0.2.4 installed OS instance on your MacBookPro5,2 from 11.5.2 to 11.6?
Click to expand...
Updating just finished... so now I have 11.6 in two installations:

- installed with OCLP 0.2.5n (downloaded 10hrs ago), over 11.5.2 installed with OCLP 0.2.4, on a USB SSD
- installed with BigSurBaseSystemfix by jackluke, over 10.5.2 installed with BaseSystemfix, on internal SATA SSD.

Used full installer, and the relevant post-install patching of the system volume, in both cases. Working fine so far.

Made a new macOS 11.6 USB, installed on top of 11.5.2 successfully after applying Step #3 - OCLP_025n Offline variant. Ample performance on 2GHz Mini3,1. 👀✌️🧐
