Changing iCal’s Default Alert Sound (Mac OS X Lion)

by hun

  1. Download and install Xcode from Apple.
  2. Quit iCal if it is running, and open your user Preferences folder. (Easiest way to open it is to use Finder’s Go menu; press and hold the Option key and you will see Library folder; click and open it; the Preferences folder is in there.)
  3. Open the file named com.apple.iCal.plist with Xcode.
  4. Right click (or Control+click) anywhere in the window, and select “Add Row”
  5. Edit the created row as follows: Key=Default alarm sound, Type=String, Value=Glass (the last value can be changed with the default sound of your choice).
