Why Format External Hard Drive Mac?

As I said already, there can be any reason to format USB on Mac, but we must know why formatting a USB drive is necessary or recommended.

Most of the people in the world run Windows on their computers and Windows uses a different file system, usually one known as Fat32.

Although Mac can easily read from and write to other filesystem formats, including Windows MSDOS, FAT, FAT32, ExFat, and NTFS formats, formatting it to be entirely Mac compatible filesystem(Mac OS Extended or APFS) is highly recommended, and necessary for Time Machine and to make disks bootable.

Drives formatted as other filesystems can work fine with macOS, but it’s not optimal and you’re more likely to run into problems than if you use macOS’ native format. So, if you’ve bought a USB drive that’s formatted as Fat32, or any other format other than Mac OS Extended or APFS, here’s how to format USB on Mac.
