Why is external hard drive read-only on one Mac, but read/write on another?

I have a Seagate Backup Plus Portable Drive.  I bought it to be compatible with both Windows and Mac, which it currently is.  It works just fine on my PC and my MacBook.  However, recently, I bought a MacBook Pro.  The Seagate drive shows up as read only on the MacBook Pro, though it is read/write on my MacBook.  It's formatted NTFS, yes, but it already works on my MacBook.  What's going on here?

Nope, one of the selling points of the drive was that it came ready to work with both Mac and Windows (the product description says there is an NTFS drive installed for use on Mac).  No hacking or installing on my part.
But I think I figured it out.  Apparentely, Mavericks comes installed with something that does not allow it to write NTFS no matter what (well, unless you go through a whole bunch of technical stuff to rewrite the software).  My old MacBook was Leopard.
I'll just reformat the external hard drive for Mac, and if I ever need to use it on a Windows, I'll install HFS+ Explorer on the Windows.  Oh well.
