I purchased a Seagate Backup Plus Slim back up 1 TB for windows and Mac. I have a Macbook Pro late 2011. I plugged it in and went to time machine to begin the backup and it indicated that the disk was not usable because it needed to be formated? How do I do this?
Got a tip for us?

New drives come formatted for PCs so out of the box you need to set the partition type and format for the mac.
In the Disk Utility Partition Scheme pop-up menu, choose "GUID Partition Scheme".
Then choose HFS+ as format type of Mac OS Extended (Journaled).
