Why need to start your M2 Mac from an external SSD or HDD?

Instead of utilizing a start-up disk, you could find that you occasionally need to boot your M2 chip Mac from an external drive or boot volume rather than a start-up disk. It will be carried out flawlessly if you boot your M2 Mac from an external SSD or HDD to perform some problem troubleshooting, perform partitioning, repair the drive, apply updates, format the entire disk, and install OS X, among other things.

Hold on Power while the M2 Mac is starting up to change to boot from a bootable external hard drive. The precise key combinations that can be utilized differ marginally from one Mac model to another for a few reasons.

Additionally, you are unable to boot your computer from just any external hard drive. The bootable external hard drive should have correct partitioning and an installation of the appropriate version of the Mac operating system (OS). Like booting from Intel-based Macs, the external hard drive can be connected to PowerPC-based Macs through either FireWire or USB connections.
