My wife has the opportunity to purchase an old Macbook from her company (a large employer) at a very good price. The company has a deal with Apple to provide thousands of Macbooks to employees. These come loaded with software, including system configurations, that are specific to the company, and which exercise a level of security and corporate-specific controls and functions which would make it non-viable as a personal machine. Will wiping it to "factory settings" and then building it up turn it into a standard Mac, or is it possible that the reset files on the hard drive have been modified such that it would retain its corporate-specific flavor? If so, can one get a dvd which can then be used to reset the machine to generic factory standards? I don't want to buy it, no matter how good a deal, if it's forever going to act like its corporate version. Thanks !
