Remember that you do this at your own risk, you could lose all your data (it's your responsibility to do a Time Machine backup first!), expect bugs and crashes, and this patcher is still under development. This documentation is more thorough than for previous versions of this patcher, but it may still be incomplete. In addition, thanks to Ben Sova, MachInit, johncaling40, and Travis Parker for their contributions to this patcher. Ausdauersportler for integrating patches for iMac Metal GPU support.This turned out to be a good way to make LegacyUSBInjector function under Big Sur, and more generally and more importantly, it was absolutely essential for improving overall patcher reliability. testheit for describing how to use a kmutil feature that I was previously unaware of.ParrotGeek for developing the LegacyUSBInjector kernel extension that allows USB to work on various pre-2011 Mac models, and for creating the 'trampoline' that allows the installer to be patched at runtime without first running Terminal commands.highvoltage12v for developing the first 802.11n Wi-Fi patches for Big Sur (no longer used by default, but still available through the -wifi=hv12v-old and -wifi=hv12v-new options for patch-kexts.sh), as well as patches used for Metal GPU support on 2011 iMacs.jackluke for figuring out how to patch the Recovery USB to bypass compatibility checks and AMFI enforcement in the absence of NVRAM boot-args settings.ASentientBot for developing the Hax series of installer patches which are so incredibly helpful for installing Big Sur on unsupported Macs, as well as for his patch to NVDAResmanTesla.kext which allows the GeForce Tesla (9400M/320M) framebuffer to work in Big Sur.

Thanks to the following people for their hard work to get Big Sur running on unsupported Macs: For 2008 Mac Pros (MacPro3,1) in particular, Big Mac is clearly a better option than this patcher (at least for now).

A primitive USB patcher for installing macOS Big Sur on unsupported Macsīy the way, if you have a Mac Pro, Big Mac by StarPlayrX is another patcher worth considering.
