Yea, Apple very briefly started making effort to support enterprise in the 90's, but quickly gave up the effort. I don't remember it well, it may have been related to the PowerPC stuff they were doing with IBM (IBM dropped their support of the PowerPC project, unfortunately).
Windows is an enterprise OS with consumer features and MacOS is a consumer OS with (half assed) enterprise "features".
Wow, I've been in IT for a long time, and this is the best way I've ever seen to describe the difference.
