Halver

Halver is a utility for OS X, designed for use with HiDPI displays such as the MacBook Pro with Retina display.

The problem: You have a Retina display, and you take a screenshot. It looks fabulous on your computer, but enormous in Campfire, on the web, and on anyone else's computer.

The solution: Halver watches your desktop. Any time a new screenshot appears, it automatically replaces it with two new screenshots:

  • A half-resolution PNG
  • A full-resolution JPEG, encoded at 80%

Now you're free to share the PNG screenshot without annoying your friends and neighbors. And the full-size screenshot is there too, but now in a reasonable file size.

Requirements

Halver requires OS X 10.8 (Mountain Lion).

A Retina display isn't actually required, although you'll end up with tiny screenshots if you use it on a non-HiDPI display. Which might be what you're going for; if so, knock yourself out.

Coded and compiled in Xcode 4.5 DP3. I dunno, it might work in 4.4, but that's left as an exercise for the reader.

Add Halver to your login items, to make sure it sticks around on the next launch.

License

Feel free to use Halver and/or its source code in any way you like, at your own risk. Just don't do anything illegal or evil with it.
