systemsetup: List valid startup disks.

systemsetup

$ systemsetup -liststartupdisks

try on your machine

The command "systemsetup -liststartupdisks" is used in macOS (Mac operating system) to list all the available startup disks on a Mac computer.

When a Mac starts up, it looks for a valid startup disk on which the operating system is installed. This startup disk is responsible for loading the operating system and launching the computer.

By running the "systemsetup -liststartupdisks" command, you can view a list of all the disks that are set up as possible choices for startup on the Mac. This includes both internal drives (hard drives, SSDs) and external drives (USB, Thunderbolt).

The result of this command will typically display the names or identifiers of the available startup disks, giving you an overview of the options you have when choosing a startup disk for your Mac. This is particularly useful if you have multiple startup disks installed or if you need to troubleshoot booting issues on your computer.
