If you purchased a new, 2020 Mac mini, MacBook Air or MacBook Pro with Apple Silicon a.k.a(processor, SoC), these instructions will work for later cameras such as the ST-i and the STF-8300 however, will not work for the legacy USB cameras. That's okay, because the method for Big Sur is actually easier to a small degree. Further, since the System Drive is now locked down and cryptographically signed, the instructions I wrote for macOS Catalina are not valid for Big Sur.
Mac users who updated to macOS 11.0.x (Big Sur) on a Mac with an Intel processor will not be able to install the SBIG drivers using the 'SBIG Universal Driver Installer 4r84' to operate the legacy USB cameras i.e.(ST-7/8/10/402/i/8300/etc.).
