macOS 11 Big Sur on Unsupported Macs Thread

What video card does yours have?

AMD Radeon HD 6970M 1024 MB High Sierra

AMD Radeon HD 6970M 1024 MB High Sierra

And what is the other machine you are using as a source for the TDM?

And what is the other machine you are using as a source for the TDM?

I tried several but I was most interested in getting my MBP 9,2 with 11.6 to work. I have already given up. I bought a Luna but its a little laggy.

Here’s a couple of pictures from a few minutes ago just as proof. 2011 iMac TDM to 2012 MbP 9,2. I used an original Apple thunderbolt cable as pictured.

I have the exact same machines.. 🤔. Maybe I’m doing something wrong.

I posted this in the "macOS Monterey on Unsupported Macs" page as well, but I wanted to say officially to hopefully help as many people as I can, that from my own empirical data, A) macOS Big Sur 11.6 is EXPONENTIALLY faster than macOS Monterey Beta 7, and B) if using OCLP to install macOS Big Sur 11.6 on an Unsupported Mac, use the TUI version, and assuming your computer can handle it, turn on graphics acceleration, (under the #5 options), to get the correct color scheme to appear while running Big Sur on your Unsupported Mac. Mine Went from being grayed out on top and bottom to this:

What version of macOS is each machine running? OCLP I assume?

 

[davemp88]

I only have one machine and its running Big Sur 11.6

Hello guys,

I have upgraded my MBPr 2012 to BigSur 11.5.7 from Mohave, then upgraded to 11.6 via OTA.

I installed the Safari 15.0 OTA, and it is unusable now. I read here some users with the same problems. But is it only happening at unsupported macs? Or is it a general problem?

I can assume I can't downgrade to 14.x now, right?

Thanks for your time!!

Not sure, but you might just try to install the very same 11.6 (from recovery) on top of your current installation and then ignore for the future the Safari 15 update.

I dont use Safari, but when i downloaded the latest one i didnt have any problems.

Thats what I usually do, seeing as how I use Brave for my web browser.

iMac 12,2 10.13.6, MBP 9,2 11.6 Thunderbolt 2 cable.

 

[Tony Vee 73]

I have 11.6 uploaded on my 2010 MBP (6,2), installed the Post-Install Volume Patch and everything is working GREAT except for 2 small issues.

-I can't enable any Safari Extensions
-The Messages app is really laggy.

If there is a fix for these issues, I'd be grateful. If not, I can certainly live with it the way is it.

Thanks for all the great work!!!

Something weird happened
My MacBook Air 2010 accepted a BigSur upgrade through the app store and system preferences.
i did nothing and even deleted a bigsur something from Saturday Earlier today.
well 17 more minutes

huh?

I updated my OpenCore config using OCLP 0.3.0 nightly build with SuPlus, disabled nvmefix kext - and my CMP 2008 and CMP 2009 - works great! Updated my old reserved 11.2.3 to 11.6 - without any issues!

 

[Macschrauber]

I tried OCLP 0.3.0 nightly to test SurPlus on Mac Pro 4.1 and BS 11.6

Ethernet Port 1 stopped working, when I plugged the Network Cable in Port 2 it worked.

confirmed it by running the same system SSD in OCLP 0.2.5 and both ports worked.

also I tried High Sierra thru OCLP 0.3.0 (with -no_compat_check) and same Ethernet glitch happened.

It's not a big thing but worth noting.

I Believe for Intel HD Graphics 4000, macOS Big Sur, OCLP should not install any video driver but it does install some kexts like Lilu and WhateverGreen and these are responsible for crashes in Big Sur.

Using OpenCore without these kexts, I have no problem, I even have Safari 15 working perfectly.

horrible slow!
but very surprised......

Hey guys, first post here.

How should I proceed to patch my MBP mid 2010 (MacbookPro6,2) to address the GPU kernel panic issue? On Catalina I've used fabioiop's fix as well as codykriger's app but none appear to work for Big Sur (yet).

Some here (eg.) appear to be using jackluke’s BigSurBaseSystemFix to install in combination with OCLP.

How should I go about doing that, assuming that’s the best way to address the GPU kernel panic?

Install pathway:

> Clean install of Big Sur 11.5.2 (20G95) on an internal SSD APFS volume, using OCLP 0.2.5
> Updated to Big Sur 11.6 (natively through macOS)
> Rebuilt and Repatched post-installation with OCLP 0.2.5 just to be safe
Everything working absolutely fine bar the occasional GPU panic crash.

So, isn’t there some way to install specifically the GPU fix, as fabioiop’s app did in the past?
If not, how do you recommend I go about this? I'd rather not uninstall Big Sur 11.6 thru OCLP as it's working so well apart from the GPU issue.

Choice of hardware is the source of "horrible slow" - good job getting it to run. Great cat-screen, too. 😽

thanks for the cat compliment!

since BigSur was installed over Catalina without a patch
the macbook is very slow launching a program , but fast when using that app.
and heavy fan noise!

this week i did read here that catalina and bigsur dont agree!
i will try a fresh reinstall, with a patch or "open source whatever"

Removing the dosdude1 and dd1 items left over from Catalina helps. EasyFind or FindAnyFile will remove them

seems like you have your ducks in a row, but can't offer BigSur help yet.
(as far as GPU, i know what that is but dont know how to tweek that, so i ignore anything XXU)

i ditched BigSur because the OsX, but running that an a 2GB MacBook air without a uppercase.
ahh, what a nice white screen!

 

[laertemeira]

Hello friends! How are you? Hope you are doing well! I was very focused in my MBP8,3. But I have a cMP5,1 now and I want to upgrade to Big Sur. It's running High Sierra, already with a R9 380 installed. Question: I need to upgrade to Mojave in order to update boot loader or can I go straight to Big Sur via OCLP? Thank you in advance!
