Cant see 4tb blue on a mac

I have a new 4TB blue 3.5 hooked through by trusty vantec USB. Winodows can see all of it fine. My mac cannot see it at all.

Hi www5,

We do not recommend to use the internal drive with external USB/Sata drive adaptor as it is an internal drive. It is best that you connect the drive in the internal bay of your Mac PC and reformat the drive by referring the link given below to make it work on MAC.

Note: Reformatting is Data Destructive and cannot be undone. Once the process begins, ALL THE DATA ON THE DRIVE WILL BE LOST!
