Installing and configuring dwm on OS X

  1. Install X11.app (it's on the OS X install disk or something.)

  2. Install dwm. You have to customize config.h a bit:

    1. Replace { MODKEY|ShiftMask, XK_q, quit, {0} }, with { MODKEY|ControlMask, XK_q, quit, {0} }, to avoid colliding with the Log Out shortcut in the Apple menu.

    If you install dwm from Homebrew, brew install dwm, this is done automatically.
