Do you like giving ratings to songs in iTunes? If so, then you've probably noticed that you are only able to rate songs on a full-star basis, not enough granularity for some music fans... there's a longstanding AppleScript hack to enable half-stars, but now there's an easier way around this issue. Macworld's Rob Griffiths found a work around, involving a simple Terminal tip to enable half-star ratings.
To enable half-star ratings, close iTunes, and open Terminal (/Applications/Utilities). Once you have Terminal opened, type the following command and press enter:
When you reopen iTunes and rate a song, you will be able to give half-stars. That simple. If you wish to make things normal again, open Terminal and type the same command, replacing "TRUE" with "FALSE."
defaults write com.apple.iTunes allow-half-stars -bool TRUE
