Mac OS X User Defaults

Defaults is a tool that allows Mac users to acces the user defaults system. It’s the tool used in my last two posts that allows you to make changes like hiding your desktop icons or showing hidden/invisible files. Since then, I’ve found a more comprehensive list of useful defaults.

To keep things simple, I’m going to refer you to a whole list of useful defaults posted by Github user mathiasbynens which he refers to as the dotfiles. I suggest you briefly read through it. Some other default changes you might be interested in are:

  • Enable key repeat in Lion
  • Enable 2D Dock
  • Enable iTunes track notifications in the Dock
  • Show all filename extensions
  • Disable automatic shadow in screenshots
  • Disable press-and-hold for keys in favor of key repeat
  • Set a blazingly fast keyboard repeat rate
  • Remove the auto-hiding Dock delay
  • Empty Trash securely

For your convenience, I’ve included the list below.
