As a number of you probably know, a little more than a week ago Apple unleashed their latest OS X major release, OS X 10.8 Mountain Lion. Over the course of the next 4 days I was upgrading various Macs in our household (of course starting with my own). One of these, my mom’s, I upgraded while she was on a trip. As it turns out, when she returns tomorrow we’ll be off on a road trip ourselves. Therefore I wrote up a document that introduces the changes in Mountain Lion to her. The link in the last sentence will take you to a minimally modified version of that introduction document if you want to see it. I hope it may be helpful to some of you especially if you plan to or just upgraded your Mac to OS X Mountain Lion.
