At this point, you've got one of two choices for Verizon LTE modems -- the Pantech UML290 and the LG VL600 (which we got) -- and neither work on the Mac. Verizon says OS X compatibility is coming soon, but if you're the impatient sort and happen to possess the Pantech variant, you may be in luck: a member of HowardForums has posted instructions on how to set it up via Network Preferences. Windows is still needed for the initial activation, and there's no promises it'll work with every Apple computer, but if all the stars have aligned just right for you, hey, congrats.
