This section is basically "Macs without official Big Sur support but with Metal support", with the exception of pre-2012 iMacs that have upgraded GPUs. (In fact, a 2011 iMac with upgraded GPU is almost equivalent to this category. Earlier iMacs may have compatibility problems caused by other components; see below.) - Late 2013 iMac: Everything should work (and, after step 8, you're finished -- no need for step 9 and later). -- 2010/2012 Mac Pro: I have received positive feedback about this patcher, but I do not know which features work perfectly and which don't. If I had to guess which features might be problematic, I would guess sleep and Wi-Fi. patch-kexts.sh (step 9) should fix Wi-Fi, but I don't know what effect it might have on sleep.

Step 9 of the installation process fixes Wi-Fi support, but GPU switching may not yet be a solved problem. @@ -57,7 +57,7 @@ Unknown status: 10. If you will be using the Big Sur installation on a different Mac (for instance, installing on a 2011 or later Mac and using it on a 2009 or 2010 Mac), it is possible that the other Mac (the one not used for installation) may try to boot off the wrong APFS snapshot. To prevent this, run zap-snapshots.sh on your System volume, to remove all but the most recent snapshot. For instance, `/Volumes/Image Volume/zap-snapshots.sh /Volumes/Macintosh\ HD`. (Or you can also do this if you are running low on disk space.) This is basically the same as step 9, but with `zap-snapshots` instead of `patch-kexts`, and without any command line options like `--2011` or `--all`. 11. After step 9 (and 10 if necessary), reboot into your Big Sur installation. 12. On 2011 and older Macs, once you have installed Big Sur, make sure to enable Reduce Transparency to eliminate many seemingly random crashes, and if icons on the right-hand side of the menu bar are invisible afterward, try Dark mode. (If you will be using the installation on a 2009/2010 Mac, it would be a good idea to finish the Setup Assistant on a 2011 or later Mac and enable Reduce Transparency before moving the installation over.) -13. (only for 2008 Mac Pros & 2010 or earlier models of other Macs) Before you move the installation over from a newer Mac, you need to set nvram variables. Normally this would be done by the set-vars.sh script in step 6, but you ran that script on a different Mac because the patched installer USB either will not boot on your Mac or will not provide a functioning keyboard/mouse/trackpad on your Mac. To set the nvram variables on the older Mac, first boot into the installer USB or DVD for OS X Mavericks (10.9.5) or older. Yosemite and later will not work!
