sorry if this has been asked before, but i searched and couldn't find anything. i also wasn't sure whether to put this under an OS X thread, but i only have the problem on my imac, not on my old powerbook or my macbook air. on those laptops i got used to be able to press the power button and have it come up asking me if i want to restart, sleep or shutdown. on my imac whenever i pressed the power button it went to sleep. so far this was ok, but sometimes when my computer stops responding proparly on the laptops pressing the power button and then shut down allowed by to shut the computer down proparly (without just holding the power button down) and then turn the computer on again. so i was looking how to make my imac come up with the prompt when pressing the power button, and found something that said to go to system preferences > energy saver > options and then uncheck "allow power button to sleep the computer". i have done that, but now when i press the power button nothing happens - the computer doesn't go to sleep or come up with the dialog (unless of course i hold the button down for 5 seconds, but that just cuts the power rather than shuts down the computer) i've searched on google could find a few sites where people said pressing the power button should come up with that dialog, but can't find anywhere where it tells you how to make your mac come up with the dialog - does anyone know how to do this?
