No reason to resort to Mac just to write markdown.
First of all, the "power" of markdown is that it's plain text, so ideally you don't need any special editor to write in it. But assuming you want syntax highlighting, try Kate with markdown mode.
If you want an instant-preview function, give Atom, which is a Github-sponsored project: http://atom.io
and specifically its markdown module:
https://atom.io/packages/markdown-writer
Alternately, you might try https://remarkableapp.github.io/
I use Emacs, but I've never looked into a markdown mode.
For presentations, I use shellshow, written by a friend of mine:
https://github.com/deltaray/shellshow
It's perl, it acts a little like less or more, but with cool animated transitions.
I'm a big fan and generally use it for any presentation I do.
