If you re worried about updating your Mac to macOS Big Sur or Catalina (perhaps due to incompatible software), or if you are testing a beta version of macOS Big Sur and don t want to risk messing up your system, you don t have to install the update on your Mac at all - you can install it on an external hard drive instead.
Installing the Mac operating system on an external drive is the safest way to get a good look at a new OS without changing anything on your Mac. It ll leave your current configuration intact and allow you to play around with Big Sur or try out the beta of the next version of macOS.

If you want to use Disk Utility to format and more often than not, re-format a drive in macOS, you may sometimes want to first choose the scheme for backwards or multi-platform compatibility. The
scheme defines the overall organization of the drive, which can feel pretty obscure, because you rarely need to change it.
You can select among GUID Partition Map, Master Boot Partition, and Apple Partition Map. For all modern Macs, GUID Partition Map is the only choice and it nearly never needs to be changed; Master Boot Partition is useful for cross-platform drives that can be mounted in Windows and in macOS, as with using the ExFAT format type. (Apple Partition Map dates back to PowerPC Macs.)
