Enterprise Level Management of Apple Mac OS X Devices

Apple products seemingly are not designed with enterprise IT in mind. They do not facilitate centralized management natively, and it’s a pain point for many IT shops. Never-the-less, companies are still being infiltrated with these devices as bring-your-own-device (BYOD) concepts gain ground.
