Setup Seagate Hard Drive Mac Link

If you need to share the drive between a Mac and a PC, do not format it as APFS. Instead, use exFAT in Disk Utility (same steps, just choose "exFAT" as the format). It works on both systems but is slightly less robust for Time Machine backups.

Once the hard drive is initialized, you can use it for backup or storage purposes. setup seagate hard drive mac
