This new hint posted over at Mac OS X Hints was a nice little way to end a Friday:
…In Terminal, type in the following command and then press Enter.
defaults write com.apple.loginwindow PowerButtonSleepsSystem -bool no
This causes the ‘Are you sure you want to shut down your computer now?’ dialog to come up much quicker too.
I didn’t mind the new behavior of the sleep button, but I know plenty who were annoyed—especially with machines that have the power button on the keyboard. It’s also easily reversible by replacing ‘no’ with ‘yes’ on that command.
