Not actually a contribution, but I'd encourage people not to write "MAC", if you mean "Apple Macintosh Computer".

It's not an acronym*, so "MAC" or "M.A.C." are incorrect and risk confusion with another technology which is correctly referred to as "MAC", Media Access Control.

Just use "Mac".

* Though people do tell me Macintosh really stands for "Most Applications Crash. If Not, The OS Hangs"...
