I'm looking to put some virtualized copied of OSX in place. We do a lot of VMware implementations but never with OSX. The VMware HCL says the 12,2 Mac Pro is certified for ESXI 5.1 but I cannot find a single person who has done it. Anyone? How do you buy the licensing? We need 3 separate OSX Servers but you only seem to be able to buy one from the App Store. Install OSX alone and then do the server upgrade on all 3 via the App Store? I'd much rather start with the OSX Server itself.
