If the choice is between these 2, I know which one I will go with:
- Big Sur with no requirement to do post install patch -> delta OTA (stock like)
- Monterey with post install patch -> full download OTA and repeated patch

The GUI version is easy to use. Use your default settings to get started. OCLP and Big Sur is a great match. https://github.com/dortania/OpenCor...s/download/0.4.1/OpenCore-Patcher-GUI.app.zip 🤲

Thanks, that helped. getting a copy of Big Sur was tough, but doable.
it the tech jargon that is throwing me off, we never used like repeat patch, post install patch and GUI until recently.

Nice, so far the GUI is really helpful and easy to follow.
i really appreciate these links, i just needed a good start.

The GUI version also teaches "OCLP-speak", an undocumented feature. ;)

Good point! Should've stayed there, too. But I won't bother trying to downgrade my MBP9,1...

macOS 11.6.4RC>OCLP_042N is a pleasant surprise on a 2GHz early '09 Mini3,1.😋

This is OTA but instead of delta (smaller size), it is the full download.

This is normal (expected) if you have required a post install patch, that would have broken the sealed system volume (SSV).

You can update in all 3 ways you mentioned.

Try OTA first, it should work. Remember to re-apply the post install patch.

Everything went smoothly. Thanks once again! Full size OTA downloaded via System Preferences, then Post Install Patches. MacBook Pro Mid 2009 still alive :)

I have been trying to upgrade my iMac 13,1 from Catalina to Big Sur. My iMac was upgraded a year ago to 16Gb RAM, a 500Gb SSD and a later wi-fi card.

However, I have a problem.

I can create the bootable USB. I get as far as downloading the OCLPatcher and it builds the Open Core no problem, but when I get to the "Install to USB/internal drive” it does not see my USB drive. The heading reads - Missing Disks? Ensure they have an EFI or FAT32 partition. It then lists "a. disk 0 which is my SSD or B. Back and please select etc.

I’ve tried using OCLP 0.1.5 and also OCLP 0.1.6 but the result is the same. I've tried Kingston and Scandisk USBs of varying sizes and in different USB port on my iMac. I've been through the whole process several times but none of the USBs appear.

I'm obviously missing something, so where do I go from here?

Hey ! I have exactly the same issue unable to find my sandisk USB. Also getting "Missing Disks? Ensure they have an EFI or FAT32 partition" Did you manage to find a solution?

Im having the same issue. Did you get it resolved?
 
Hi, I installed MacOS Big Sur 11.5.2 on my MacBook Pro 2012 (9,2) and after installation, the Software Update show me 11.6.3 version to install, but not install. Looks like upadating but after restart, the version is the same (11.5.2). What to do in this case?

Just tried OCLP V 0.4.2 on a Non-Metal iMac and the Catalyst Scrolling is now WORKING! That's so amazing! I am over the moon 😅 I'd like to thank all the developers involved for your excellent work to get this critical feature working on non-metal Macs.

OTA has three steps during the update process - Download, prepare, install and all clearly shown in the Software Update CP thoughout the update process. Go to /Library/Updates ƒ and delete eveything in there and try the update, again. 🚧

I ended up downloading by OCLP and installing via USB Drive. Thanks for the tip.

Re: OCLP V 0.4.2 "Resolve Catalyst Scrolling on non-Metal GPUs"
Upon further testing, it appears the iMessage iCloud sync function is not working properly whilst the scrolling is working smoothly. It only achieved partial sync when running Big Sur (11.6.3) and not sync at all when running Catalina (19H1713). The Photos app "My Photo Stream" sync is also not working when running Catalina. I've not tried Monterey yet. All the iMessage sync issue is photo/video related. Text sync seems working correctly.
Update-1: Updated Monterey and it has the same iMessage iCloud sync issue although the symptom is slightly different whereby the most recent photos/videos can be downloaded correctly (because it has just been updated and had not been used for a few months) but the old messages (eg. > 2 mth) can't be synched (the little iCloud gear just spins forever).
Update-2: The "old message sync issue" is across all macOS.
Update-3: The issue is now only limited to the old messages with Big Sur and Monterey after turning off the test iMac for around 8 hours. The most recent photos/videos have shown up under all macOS.

Solution:
Well, I've finally found a solution to go back to the old messages: use <Page Up> key to fetch old messages in iCloud Instead of using mouse to scroll back. If you don't have the <Page Up> key, use <Fn> + <Up Arrow> keys instead.

This issue may not be OCLP related at all. Sorry for the confusion.

Ok, I did it: Big Sur on my 8,1 is now bread and butter. Migration worked out well. Apps work or don't work as expected and tested before. What I hadn't noticed before:
  1. Menu text is always white - no matter what I use as desktop picture or whether I use dark mode or not. So I use dark wallpapers.
  2. Maps works well - but crashes if I use Search top left. Finding a route works fine, though.
Thanks a lot to those who made this possible!
