All The Seagate Expansion External Drives Now Come ExFAT Formatted
Previous Expansion drives were NTFS formatted. And you might inherit one.
NTFS is a file system a Windows PC uses.
Your Mac can read an NTFS drive. But when you want to put your files on there. It’ll appear like it’s somehow blocked.
To use it fully on your Mac you need to format it first. You can find how here. Take 5 minutes or less and format your Expansion for your Mac. Click on the link text.
Now the latest drives come ExFAT formatted.
ExFAT is compatible with Mac and Windows. And this means you can share your drive.
But, I’ve noticed some drives come formatted with a Master Boot Record partition map. A Mac needs a GUID partition Map. And those drives will need to be formatted so they work consistently on your Mac.
One thing. You can’t use an ExFAT formatted drive for a Time Machine backup on your Mac. For a Time Machine Seagate backup you’ll have to format to an APFS file system or to Mac OS Extended.

Connecting Your Seagate Expansion Up To Your Mac
Your Mac powers your Portable Expansion external hard drive. And the Expansion SSD (Solid State Drive) through its USB port. The desktop Expansion drives need a power outlet.
Your portable Expansion hard disk drive is a USB 3.0 drive.
It comes with a USB cable with a USB type A connection at the end you plug into your Mac.

Your modern MacBook Pro, MacBook Air models have USB C ports.
You just order yourself a USB C to MicroB cable. Or a USB C to USB type A adaptor cable and plug right in.
The Expansion SSD drives come with a type C USB cable in the box. So you can plug right in and expand the storage of your Mac’s internal drive.
