  1. Thanks to the unsupported macs community we’ve managed to get Apple’s Big Sur installed on one of the oldest unsupported machines. A big thank you to BenSova, for making these possible. This video is about the installation of Big Sur on an unsupported Mac I’ll leave links to the Discord and Reddit page if anyone needs help.
  2. Normally, you can obtain a copy of macOS Big Sur via System updates under System Preferences or can simply use App Store. But as you're using an unsupported Mac, you won't be able to get new updates as you're using unsupported Mac and Apple will block updates for new OS.
Unfortunately he didn't continue with patches for newer OS:s, but have helped with a new patcher. This patcher even handles Macs with graphic cards from 2008 - 2011.
Using the patcher i got the mentioned Mac up and running with Big Sur after just over an hour.
Fantastic !!!

Good luck !

Remarks
  • Erase/format the MAC HD/SSD before installation !! I really think that this does it more simple for the installer !!
    • 'Mac OS Extended(journaled)' with an old non SSD HD
    • With en SSD use 'APFS'
  • The Mac rebooted several times during install.
  • Don't remove the USB until at the very end.
  • If you, like me, have a Mac which need the legacy video acceleration support please note that the Mac have a painfully slow display update before you have applied the 'Post-Install volume Patch'.
  • Updating the Mac from Big Sur 11.4 to 11.5, made the messages.app stop working fixed in release 0.2.4
  • Please note that 'Nightly Builds' are available but are for testing purposes only !!!
