macOS 11 Big Sur on Unsupported Macs Thread

@justperry and @TA 455SD ,

I was able to get my error sorted out on my 2012 Mac Mini. I think at this point, my installation is successful and I don't have any errors that currently pop up.

One last quick question for you:

After Step-17 on the patcher guide:
github.com

GitHub - barrykn/big-sur-micropatcher: A primitive USB patcher for installing macOS Big Sur on unsupported Macs

A primitive USB patcher for installing macOS Big Sur on unsupported Macs - barrykn/big-sur-micropatcher
github.com github.com

Did you have to do anything else as a 'post-installation' step? Just wanted to make sure I covered everything and I'm officially done on my 2012 Mac Mini with installing Big Sur.

Thanks guys!

hi where can I download the beta version of CCC?
Click to expand...
Do you have a paid CCC application on your hard drive (or SSD)? If so you can find the download from:

Launch CCC,
In CCC Preferences, at the top select Software Update,
Select "Inform me of beta releases" box, close the window,
Then under Carbon Copy Cloner in the menu, select 'Check for Updates...",
You should see the beta.

If you went all the way including step 17 and wifi is working you are done.

Hi all,

I apologise if this has already been mentioned, but I'm finding it difficult to locate the info that I need. Everything seems to be working great (including Bluetooth), with the exception of WiFi.

I installed macOS Big Sur, directly from a fresh install of Mojave (as this is natively supported on my Mac Pro 5,1 (flashed 4,1).

I followed this guide exactly:
(considering this is the place I purchased the Mac from a couple of years back).

The WiFi was working under Catalina (using DosDude's patcher at the time), but now it's using OpenCore and I must say, it's nice to see a Boot Screen again :)! (although I wonder if this will ever risk being overwritten and leave me in the dark).

There's a lot of chat about updated kexts, so I'm guessing there's a fix out there.. but does anyone know of a way to simply install the WiFi support, without risking any other areas of the OS, considering this is a pretty clean install?

Maybe an installer or script would be nice?

Thanks!!

in the hackitosh community there is a kext wizard application that would allow you to drag and drop kext and rebuild caches. seems like it should also work here. i would backup before messing around with kexts.

This does not work here with Big Sur!

Please do not post assumptions backed up by no experience. The complete process has changed in a way that you need a complete new approach (see micro patcher docs or the patch-kept.sh script for those willing to read code).

I don't know if it will work in your application but Bens patcher creates an app installer that runs the kexts

I am back again and this the news is not good for my imac. Today i powered on the iMac and on the grey apple screen the progress bar froze just at the beginning of the Apple logo. It stuck there with full blast of fans. I forced shut down the imac and thought will select Catalina volume to boot ,again similar issue.
I also saw few horizontal lines on the display and the display froze.

in conclusion it seems the display card bios may have got corrupted or the display card has issue.
So after bringing the imac from the graveyard and using it for almost a year I have felt good and contented.

now I will not be repairing it. Time to move on.
I thank all for good support and help.✌️

This is not a patcher, it is just a GUI to run the @Barry K. Nathan micro patcher. If something goes wrong you have to go back and read the real docs.

I realize that , I am referring to app for lack of a better word that Bens creates after it has installed Big Sur , it automates the process of the kexts
What Ben has done is make a simple GUI that is not available in Barrys patcher

Please read micro patcher online docs, last section!!

P.S.:
I already created feature request to add the plist modification by default. But this will take some time...

Download gibMacOS-master at GitHub. Run GibMacOS.command in Terminal. After switching catalogs you can look at the url, download the sucatalog, look at in TextEdit and search for the pkg.

And ... just to be precise, the version is Beta 11.1 (20C5048l). It is not a final release -- just the first of probably many betas for 11.1.

I've tried but only show 11.0.1. The way I select "1" start to download some files
How could I found 11.1 version?
How could I copy "URL" instead start download?

Thats a great request @Ausdauersportler . Hope to see some solution soon, meanwhile I guess I can't do much but wait.

/Volumes/Install\ macOS\ Big\ Sur\ Beta/remount-sysvol.sh. This command has beta mentioned. Will it run ok.
