usb mass storage is a generic driver that havent changed in years your current wd ext hd and the new one use the same driver and the same driver is used by 10.6.7 and maverick 10.9
usb 3 is usb2 backward compatible
they just write those things because officially supporting every device and os ever made would be infinitely expensive for a company

Also, the first thing you should do after buying a WD drive is to format it as HFS Extended (Journaled) and not install ANY of their utilities but instead use reliable applications like CarbonCopyCloner or SuperDuper - or Time Machine.
