Sorry SuperDuc but my solution was to bin the MacPro and buy an M2 Mac Mini. I still have the Highpoint card, but in a Windows machine.
Got a tip for us?

Are there any drawbacks if I upgrade my MacBook Pro 2012 (maxed out RAM and SSDs) from Catalina to Big Sur? Is it significantly slower?
Some features aren't available on Catalina (no webp support in Safari, many websites don't show images), so I'm contemplating upgrading to Big Sur using OCLP, but I'm afraid I'll regret that if there are cons.

Speaking for my MacBook Air 2012: With an upgraded BT/WiFi module, the model is so perfectly supported, you don't even need OpenCore for Big Sur, it's simply enough to skip the compatibility check of macOS with:
Code:
nvram boot-args="-no_compat_check"So all OpenCore has to do for a stock model, is patch the WiFi module.

As you can see, I have two MBPs 2012 in use (9,1 and 10,2). Ventura/OCLP is still work in progress, but Big Sur and Monterey work very well. Since Big Sur won't be supported after fall this year, I would consider Monterey.
Just read and follow the OCLP instructions very carefully!
So if I got this right all you have to do is disable SIP(and keep it off), set the boot args, manually patch the WiFi module and you should not need the OpenCore?
I was under the impression that in a later macOS systems it is not as easy to replace kexts or perhaps the real issues in doing so start with Monterey and later?
Sorry, that I do not know. I was only referring to a system (MacBook Air 2012 13") with an upgraded WiFi card that therefore needs no patching of any kind at all (for Big Sur).
Your approach seems logical but as I understand, it’s easier to let OpenCore do that job "non-intrusive" than manually modify files on the sealed-system-volume. And even safer and update-proof.
@khronokernel explains in greater detail what obstacles they actually had to overcome to add WiFi support for non-BCM94360/94350 cards.

OCLP_068n has finally fixed this shutdown / restart issue (still without the chime) for the iMac10,1. The safari also performs correctly. Thanks to all the developers (in particular, the non-metal developers) for the ongoing improvement of very old Macs with your talent and persistence.
I have a 2011 MacBook Air. 11" screen. MacBookAir 4,1 SMBIOS.
The screen got too small for my old man eyes and won't accept more than High Sierra 10.13.6. So a few years ago I plugged it into the TV in the living room and since then I use it as a multimedia drive with Apple BT keyboard and mouse, with complete satisfaction. Logically its performance can be better.
Yesterday I was curious to try OCLP on this laptop, never worried that it wouldn't update but curiosity to see how well OCLP works on such an old Mac was strong.
I downloaded OCLP 0.6.7, from this app I downloaded Big Sur, prepared the EFI on a USB stick and installed Big Sur. There were no issues during the process. Everything was smooth and good if a little slow. And Big Sur runs very well on this laptop, with better graphics than High Sierra and some obvious improvements like Apple TV and Airdrop.
When starting Big Sur for the first time there were black boxes on the toolbar in Safari and some applications but choosing Display-P3 as display color profile (as advised by OCLP developers) solved the problem.
We often compliment OCLP but it is true, what they have achieved is impressive.

I'm having this same issue, did you ever resolve it? It works fine in High Sierra, Mojave, Catalina, and even Windows 11 but locks up Big Sur and Monterey with the NVME kext in the extensions folder.
I just updated today with OCLP 0.4.11. All is well! I don't think any Big Sur updates would be significant enough to cause any problems at this point. Soon enough we'll have 11.7.9 since it's in beta.
I uninstalled OCLP from my 13 inch Mid 2012 and Big Sur is working fine(with ethernet that is) and all of a sudden content caching started working as well. I have Mojave, Big Sur and Windows 11 Pro(Boot Camp) booting natively without issues. It is ridiculous for Apple to remove just the WiFi support, hopefully they will re-add it back in one of the final updates.
Hi, I am sorry if it’s has already been discussed but the thread is very long and I just want an honest answer. My budget is very low and I can get a Mac mini 2011 i7 for dirty cheap. However I am running big sur on my Mbp. Is it possible with the patcher to also run on the Mac mini 2011 i7 with the Radeon graphic card without any glitches or strange occurrences ?
Many thanks.
Many thanks.
I had a 2011 MBP8,2 i7 with a small SSD and 16GB installed. It ran fine using OCLP 0.4.11 and the latest Big Sur. Should be similar on the Mac Mini. I have seen reports of people even installing Ventura successfully, but I never tried that. That MBP is now doing duty at a friend's house. Tough little 12-yr-old monster!

Big Sur 11.7.9 works great with OCLP 0.4.11.
Hello:
MacBookPro 5,2 17" and successfully installed BigSur with OCLP. Really cool.
Now I got the FileVault problem... won't work.
Reading around, I see is that I had patched the ROM with dos dudes APFS BootRom patcher that made work Mojave for a long time natively:
but I never kept my" MacBookPro5,2 backup.bin " bin file to restore it ... damm. For what I can see, there would be no other way to get FileVault to work.
The chip I have is the one in the middle, as in the picture: "3205D"
Would be anyone with the same machine generous enough to send me a copy of theirs (or create a backup) with a PM?
Here is the link to download the romtool to dump it
Would there be any problem?
I should've kept the file
any other suggested solution?
Thank you anyone for any help
EDIT: Managed to get it sorted. Adding steps if anyone else ever needs:

Your system ROM has been successfully patched, and should now be able to boot from APFS volumes natively. A backup of your system's original ROM has
been saved to "/Users] MacBookPro5,2 backup.bin". It is recommended to
save this file in a safe location.The chip I have is the one in the middle, as in the picture: "3205D"

Hello guys!
What do you think about install Big Sur to a Macbook Pro 2010 with SSD but only 4GB of RAM? I'm having a good fight with High Sierra since it refused to install a few times but finally did it and also, i installed the last security update (006) and boom, wifi hardware not detected..
Total caos.
Anyone with a Macbook Pro 2010? It worth to install Big Sur on it?

I'll try with Big Sur to see if works fine.
I have a Macbook pro 5,5 (Mid 2009) with an SSD HD and upgraded to 8 GB of RAM. I installed Monterrey using OCLP 0.6.8---Monterrey actually was smoother and seemed to have less "glitches" than Big Sur on my 5,5......
I've been using Mojave for the past year on a fully-loaded Mac Pro 5,1 (w/ Radeon RX 580 and BCM943602CDP WiFi/BT) in order to maintain occasional use of Dashboard and 32-bit apps, but there's been an increasing number of websites and software updates that are no longer Mojave (or Safari 14) friendly.
Contemplating an upgrade to Big Sur, preferably because I won't be bothered with security updates as it's pretty much EOL'ed at this point. I can resort to Mojave via VMWare Fusion for unsupported 32-bit apps and Dashboard (which is admittedly becoming fewer and farther between).
As a newbie that has yet to dabble with OCLP I just have one question: is it best to use the upcoming latest version (0.6.9) for upgrading to Big Sur? Or is it better to use an older version that's more optimized for Big Sur installations?
Thought I had read somewhere it's preferable to use a specific older version depending on which OS you want to install/upgrade. Not planning on any multi-boot environments (other than the existing Windows 10). I would just like to do a strict Mojave -> Big Sur upgrade in order to squeeze a few more years out of this thing until an M4 or M5 Mac Studio is ready.

Well I think you need to make some video card check and also check the internals, however if you installed the macOS Mojave on a 5,1 Mac Pro I don’t think you’ll have any trouble with patching it to Big Sur. The other thing to consider is that macOS 11 will be extremely buggy on 5,1 Mac Pro since 10.14 is the last officially supported OS by 5,1. I think you should try patching your Mac to 10.15 first using the OCLP or using the dosdude1 Catalina patcher, and then try doing a Big Sir installation on a separate partition to about data loss.
Use oclp 0.4.11 and everything will work as it should. 100% . Im on a cmp 5.1 and use this too. But im just with big sur, no multi boot.
I second this recommendation, and I have seen a dev who is active in the OCLP development also say no version greater than 0.4.11 is required for Big Sur and Monterey. Ventura introduced several hard-to-deal-with issues, and several versions of OCLP were released to deal with Apple's vagrancies, resulting in 0.6.8 and 0.6.9n, both of which work near perfection on my hardware, one old iMac from 2014. You should be good using Big Sur and that cMP.
