macOS 11 Big Sur on Unsupported Macs Thread

[Barry K. Nathan]

Doesn’t work for me, user is Administrator in system preferences, OS installed on separate Volume, but in the same APFS container. Could that be a reason?

Yes, that could be the reason. Installing Big Sur in the same container as earlier releases is known to cause problems. It's in Apple's release notes for developers (but there are other problems beyond "updates can no longer be installed on the previous versions of macOS"):

That's interesting, will try splitting it after decrypt finishes

Anyone try on a MacPro 3,1 with GTX680 (and hopefully BCM94360CD) yet?

After applying the launchctl setenv DYLD_INSERT_LIBRARIES $PWD/Hax.dylib in terminal my mbp mid 2012 locks up and won’t let me open any applications. And freezes up in the installer. Any advice?

Try using my script (https://github.com/4ndv/big-sur-plz), it injects dylib only for InstallAssistant, not system-wide

Alright. I will check that out. Thanks!

would it be possible to install Big Sur on an Apple TV as an extreme budget Mac? Seems like the 4K model would be up to snuff for basic computing.

No luck

That's interesting, could you provide terminal output, including last parts from the installer?

Even more interesting, there are output from the patcher, but for some reason it's not applied 🤔

It'll never work. Apple TV is not a computer per se.

What is it supposed to look like. If I may ask

Output looks the same as on my machine, but for some reason patch did not applied for you, I'll check everything myself tomorrow, because my FileVault is decrypting for another 5 hours :\

My 2012 MacBook Pro has an upgraded Broadcom BCM43xx 1.0, (WiFi 802.11AC) hopefully this might get around the lack of WiFi drivers for this model.

I think we have identical cards. Here is mine, sorry for russian language on this screenshots)) Only problem is internet recovery not work with this card, but it's a small problem.

Just wanted to take the time and thank everyone once again for all of the hard work you are doing to make it possible to run Mac OS Big Sur on unsupported Macs.

Well, it's not so bad.
