macOS 11 Big Sur on Unsupported Macs Thread

[psbelectric]

Hi,

I found this at GitHub to download nearly all versions of current macOS (public and developer).

Just follow the instructions after downloading the Terminal scripts / commands.

Mind you, this morning here in Melbourne, Australia download stopped at around 3GB

Regards!

Might upload the app, many here don't know how to built an app.

Status says it's A-OK now, does anyone have a good link to use for 11.0.1 InstallAssistant to download?

 

[richiemouse]

As in wipe the disk???....Nope, just install in place as in Update

Thanks! So basically I just patch the new update etc etc and install on top of my current installation, am right?

Well, i suppose it's not ok. This is like Mac App Store looks for me now.

Well, I have the full Big Sur Installer downloaded on my MacBook Pro. The download was completed about 3 hours ago.

Downloading for me too but I feel its strange! I could never download catalina from the app store as my mac is not supported. Unless, of course, it is due to CatalinaOTAswufix.

HELP. Installing on Mac Mini 2012. Following @Barry K. Nathan instructions. Stuck at Step 10, keep getting no entry symbol on the black screen. Tried rebooting a few times, tried resetting NVRAM, then repeating Step 9, then Step 10 get to the No Entry sign again. Help. Thanks

PS: The No Entry sign I get is just a circle with a diagonal line through it and a link to some apple boot help website.

I was able to download Big Sur from this link. Unfortunately, I can't find a suitable USB drive, so I'll have to wait to install this until tomorrow.

Late 2013 iMac

No

So you're trying this on a (Late 2013 iMac) also?

Yes, I will be trying this install on my late 2013 iMac tomorrow. I don't have a fusion drive either.

 

[psbelectric]

Success!! Thanks Barry and crew!

Regards.

I'm going to try it tonight but I'm still not 100% sure of what I need. I have the InstallAssitant downloaded and opened it and the big-sur-micropatcher-main. zip

Now the longer version

This is for a 2012 Mac Mini and almost sure for the MBP from the same year, others, especially earlier macs need extra steps, for that read the manual on micropatcher page.

1. Have a USB stick handy, or an external disk, or a dedicated partition.
2. Download the full installer.
3. Download Micropatcher from here.
4. Open Terminal.
5. sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/Install\ macOS\ Big\ Sur\ Beta --volume /Volumes/***
*** is the disk label you install the Installer onto, so the USB stick, I dragged and dropped my USB stick onto the terminal, the path will be automatically added.
6. Input your password.
7. It will erase your disk so be aware not to chose the wrong one.
8. Input "Y" if asked to erase.
9. Wait until it's finished, could take a while dependable of what kind of media you use.
10. Unzip the downloaded micropatcher, drag the micropatcher.sh file onto the Terminal window, then enter.
11. In Terminal type sudo and then a space, next drag the install-setvars.sh onto the Terminal window, hit enter.
12. Restart after it is finished.
13. Hold Option key right after restart, keep holding it until you see the bootpicker.
14. Chose the EFI disk, it will instantly shut down.
15. Start up again and again hold the option key for the bootpicker.
16. Chose the USB installer, wait for the installer to open.
17. Chose the disk you want Big Sur installed onto.
18. Wait for probably an hour or so (Have a coffee or a beer in the meantime 🍺 ) if you install from a USB stick, probably half of that if the installer resides on a SSD medium.
19. Restarts multiple times.
20. Almost done.
21. The next step is for WIFI, Wifi does not work OOTB on a 2012 Mini or 2012 MBP....
21a. Restart for the last time after it booted into Big Sur, you may restart before login or after login, makes no difference.
21b. Hold the Option key again to get into the USB installer, there are other ways but this one is the easiest, chose the USB installer, next open terminal from the menu.
21c. Input "/Volume/Image\ Volumes/patch-kexts.sh" and hit enter, when finished enter "reboot", both without the quotes.

Voila...done...a working Big Sur OS.🍺🍺

Edit: Do not forget to thank Barry K. Nathan

Can I use this with 2011 MacBook Pro with updated WiFi card for coninuity

I installed a 256GB SSD a year ago that 5400 RPM HDD was horrible

Thank you so much guys I followed the instructions and now the iMac late 2013 of my family runs Big Sur! And it does run well (I changed the hard drive to a SSD last year)

I have a question though: will I be able to get the future updates of Big Sur normally? (Like a future macOS 11.1 through the Settings)

I installed it on a mid-2012 MacBook Pro. It’s running awesome, no idea why it’s not officially supported.
