Can I install macOS Big Sur from external drive?
If you’re worried about updating your Mac to the latest macOS Monterey beta and don’t want to risk messing up your system, or just updating to Big Sur and you are concerned about incompatible software, you don’t have to install the OS update on your Mac at all – you can install it on an external hard drive instead.

You can store and run applications in the non-standard /Application location on OS X, which means you can keep things on your external drive and run them from there.

Is it possible to boot an M1 Mac from an external disk?
Unfortunately, on an M1 Mac running macOS 11.1, the Data volume is usually left behind, and any attempt to eject it will result in your being told that it’s still in use, while trying to open the volume denies that it’s present at all. In the end, I just disconnected the disk, and no howls of anguish came from the Mac.
How can I install Big Sur on an external disk?

Can you install Mac OS 11.1 on an external disk?
Installing macOS 11.1 on that external disk appeared to proceed identically until the installer reached the final minute, where it took much longer than the Thunderbolt disk had done.

How do I unmount the system disk on an M1 Mac?
Clicking on the Eject tool for the System disk brings a helpful dialog which offers to unmount both System and Data volumes. Oddly, on Intel Macs running Big Sur, the Data volume isn’t shown as a separate volume, but on M1 Macs it is.
