Mac first person shooter fans, get ready for a lost weekend. Yes, it took Activision and Aspyr nearly two years to port this $1 billion game franchise, but Call of Duty Black Ops Mac is finally here and ready for download right now.

As of this writing, Call of Duty: Black Ops Mac buyers have a choice of paying the same price ($49.99) at three vendors:

• Amazon (download)

• Mac App Store

• GameAgent

Of course, you will need a Mac capable of running this title and the minimum specs are consequential: Mac OS X 10.7.4, 2.4 GHz Core 2 Duo, 4GB RAM, 15GB disk space and an ATI Radeon HD3870 (or higher) with 512MB VRAM.

Once you’ve made the decision to buy, perhaps the only consideration here is which vendor won’t charge sales tax. That said, sales tax on the Mac App Store is pretty much a given, and your mileage will vary (i.e. what state you live in) when considering either GameAgent or Amazon.
