Somebody who uses an Apple/Macintosh computer. There are two kinds of Mac users

1. The Mac user who uses a Mac because s/he has to. They probably work in the editing, developing, and/or scientific communities and use a Mac because the software that works best for what they do just so happens to run on OS X. Far less obnoxious than your stereotypical Mac user (see below) and while they may enjoy working on an Apple, they probably would probably switch to Windows or Linux without complaint if they needed.

2. Also known as a Mactard or a Macfag, these are the users who are obsessed to the point of cult-status. They buy Apple products because they're made by Apple, they spend all day bashing Windows because "Micro$oft is evil!" will try to convert everyone within eyesight to the cult of Mac, and go to bed after praying to Steve Jobs. Everything they do on a Mac they can do on Windows, but they don't want to be like everyone else so they choose what their former friends didn't use. If they had to use Windows, even for a minute, they'd gripe and complain the entire time.
1. "After you're done working on that mRNA strand in Geneious, drag and drop it into EnzymeX to find the right enzyme for that BON1 strand you took the RNA from."

2. "Yeah, I'm a Mac user, and I love it. You use Windows? Don't you know that Win-DOSE has over 100,000 viruses?! Switch to Apple, you won't get viruses, nor will you have to worry about adware or spyware or having to help Bill Gates buy another house! Also, look how pretty the graphics are! Sure, you can run Photoshop on Windows, and sure I use Microsoft Office on this, but they run sooooo much better on a Mac!"
