If you've deleted the recovery partition on your Mac, you might find yourself unable to use certain features, like FileVault and Find My Mac. Recovery Partition Creator is a simple script that will bring it back.
At some point along the line, I deleted my Mac's recovery partition, only to find that the darn thing's actually important. Luckily, it's very easy to restore. The easiest way, I found, was to use Recovery Partition Creator, an AppleScript by Christopher Silvertooth that does the heavy lifting for you.
Just download the script, double-click on it and follow the prompts. You'll need a copy of "Install OS X Mavericks" downloaded from the Mac App Store, and you'll need to be patient -- sometimes, it can take a minute or two for the dialog boxes to pop up. When it was done though, my recovery partition was back in action, and FileVault and Find My Mac worked beautifully.
