Why does this matter?

Seagate External Drive Setup When You’re Only Using Your Drive On Mac

If you happen to have files already on your Seagate drive. Copy them off somewhere safe first before formatting.

Well, your Seagate external hard drive in ExFAT will work on your Mac. But may well give you strange errors down the line. Leaving you scratching your head wondering what on earth is up with your drive.
And the issue could be as simple as the partition setup isn’t quite right for your Mac. Modern Window PC’s use the GUID Partition Map as well.
Format your Seagate hard drive on your Mac as ExFAT with a GUID partition Map. For a drive to share files between a Mac and PC. It takes less than 5 minutes to set your drive up right. And this goes for Seagate SSD’s as well.
NTFS Seagate Portable Drive Mac Setup. Or NTFS Seagate Desktop Setup
When you have a Seagate NTFS portable or desktop external drive. The key to deciding the best way to set it up on your Mac is how you plan to use your drive.
Is your external hard drive mainly for your Mac? Or mainly for a PC and just occasionally for your Mac.
If you’re mainly using your Seagate NTFS drive on your Windows computer. And only copy files off the drive onto your Mac. Then leave your drive as it is.
Macs can read a Seagate NTFS drive. And you can happily copy files off the drive your Mac.
But, if you need to write new files to your drive. Or update existing files.
You’ll need another solution. As Macs can’t put new files on a Seagate drive in an NTFS format.
You can download and use driver software on your Mac. Seagate Technology provides the Paragon NTFS driver software with some of their drives.
If you’re buying your Seagate hard drive for your Mac. And the ideal external drive for you just happens to be in NTFS. But you plan on only using your external hard drive on your Mac.
