Q: Mavericks' strange power button behavior.

I have MacBook Air 2013, Mavericks installed and I know that power button's behavior has been changed in Mavericks.

 

 

I wanted to pop up the old system shutdown menu. Thus, I tried to press power button for 3 seconds.

 

 

However, my MacBook Air doesn't allow me to do that. It immediately goes into sleep mode as soon as I put my finger on the power button.

 

 

Then, I press power button again to wake it up. After that meaningless and redundant actions, pressing power button for 3 seconds does work.

 

 

On the other hand, the alternative method, pressing Control + Power Button always works.

MacBook Air (13-inch Mid 2013), OS X Mavericks (10.9)

    I mean,

     

    I need to tap the power button twice to sleep and wake my mac, and then tap it for 1-2 seconds to pop up shut down dialog.

     

    In short, I need to tap the power button three times.

    I have the exact same issue! To be clear, we are aware that the power button functionality is different in Mavericks and that a 2 second hold should bring up the dialog. However, the computer sleeps immediately as soon as the power button is pressed, so holding it for 2 seconds doesn't work because the sleeping computer doesn't know that you are holding the button longer. If the power button is tapped to wake it back up and the power button is then immediately held for 2 seconds, for some reason the computer does not sleep immediately and the dialog works. The problem here is that you need to sleep and wake the computer before the button works as described in the knowledgebase article. Has anyone else seen this or found a fix/explanation? If not hopefully this is just a minor bug that will be fixed in 10.9.1.
