After finally installing Mavericks on my older MacPro that I keep around, I was surprised when configuring zsh. I was installing OhMyZsh when the installer balked because I didn’t have the command line Git tools installed. Then a dialog box popped up and asked if I’d like to install the command line tools for me. Pretty neat. I’m not sure if it happens with previous versions of the Mac OS, but I don’t remember it happening.
I guess I’m sort of a slacker, but I just noticed that you can use markdown in the WordPress editor.
