This patcher hopes to allow any user of any knowledge to patch their Mac, while still giving you freedom on how you want to use your Mac.

To install a new or updated kernel extension in macOS Big Sur, you can do either one of the following:

I'm having an old MacBook Air 4.2, (mid 2011, SSD, 4 Gb memory), which have been running Catalina for quite some time despite that the max OS is High Sierra. I have been using the great work by dosedudes1 and his Catalina patcher.

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 !!!

Remarks

Mac Os Big Sur On Unsupported Mac

  • 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 !!!
