Hi Chris

Pretty much any drive can be reformatted for the Mac, so you'd be able to erase 
that drive in Disk Utility. 
You'd just need get the software that comes with it, as it would be Windows 
only. However it would/should work with Time Machine ok anyway. 

A few things to consider though. Some of this is my own experience and personal 
preference so others may disagree or have different experiences......

1) Just be aware that the larger the drive the more you'll lose should it all 
fall over in a big heap. eg someone with 2x 2TB has less to lose versus someone 
with 4TBs. So the bigger the drive, the more you store on it, the more gets 
lost if the drive falls over. So really need more then one backup "just in 
case". 
2) If the computer doesn't have USB3 then it will just drop back to USB2 so a 
little slower to access. 
3) I'm not a huge fan of Seagate gear. Again, this is my own experience and 
personal opinion. I've had more of their gear fail then any other brand. (And 
they were the brand that had a large failure rate in iMacs a few years back). 
They may be slightly better now, but I'm still a bit cautious. So I'd just be a 
bit cautious of not "putting all your eggs in one basket". Just make sure to 
cover yourself should anything happen to that drive. (Though the same applies 
for any drive really). Whereas Western Digital I find really great and it's my 
"go to" drive brand. I just find them more reliable and better follow service 
if needed. Again, just my experience. 

But to answer your question again, yes it should work fine once reformatted. 

Kind regards
