A computer running a Macintosh operating system, either the old Mac OS 9/below (aka Classic), or the current BSD-based Mac
OS X. These days a "mac machine" is almost assuredly manufactured by Apple Computers, because for some
stupid reason
Apple decided some years ago that no one else but them could make Macintoshes. (Editorial: I miss PowerComputing).
This phrase is usually spoken by an older woman who knows next to
nothing about computers, as would the phrase "windows machine". And it's not sexist of me to say that, because it's just a fact. There's nothing wrong with being an older woman.
Older woman: Excuse me? I am having troubles with my
stupid mac machine. It won't let me connect to the
internet!
Person: Let's see... it doesn't look like you have any means of connecting to the internet. No phone line, no cable modem, no wireless, nothing.
Older Woman: So?
Person: These things don't just happen on their own, woman.
