Q: macOS Sierra - hold down power button to enter sleep mode

I recently updated my MacBook Air (13-inch, Early 2015) model from El Capitan to macOS Sierra v10.12. Before the update, holding down power button for 2 to 3 seconds put the machine in to sleep mode. It doesn't work properly after the update. Holding down power button to enter sleep mode works only once after every start of the machine.

 

I know there is an option to enter sleep mode using Ctrl + Power button and then selecting one of the three options from Restart, Sleep and Shutdown, but that needs 3 more clicks and taps and is not quick. Also, irrespective of any app that is open, pressing power button worked well before the update, but now I need to be on the desktop to even make Ctrl + Power button work.

 

Any fixes available to this? I am missing the old way of putting my Mac to sleep I don't remember whether I did some tweak in my Mac or was it a default functionality..

MacBook Air, macOS Sierra (10.12)

    I used chat assistance and was recommended a reinstall and to contact Apple tech team via feedback form.I did not reinstall the OS but I did use the feedback form to report the issue. It has been 2 days and haven't received a reply yet. Any help is much appreciated!

    The exact same thing happened to me and I noticed it after the 3rd day of purchasing the 12 in gold MacBook (early 2016). I thought it was just my computer because my old 2012 macbook pro goes to sleep every single time I hold the power button for 3 seconds. It makes me feel better to read this because I wanted to take my macbook to the pale store and fix it or get a new one.

    I have absolutelly the same problem. MBAir 2015.

    It is a bug, so you can do nothing to this. We have to wait for a bugfix build.

     

    ...do no read that two articles from Braden85 (Comunitiy specialist), it has nothing to do with this problem so it is waste of time.

    You are right, a short press of the power button never puts it to sleep, but holding it just of half a second does. So not 2 or 3 seconds that you perceive, but quite shorter hold would do.

     

    Having just tested the above statement, it seems that my - well actually my wife's - MacBook's power button works fine again, for some two or three days now. But I can not be confident this will stay so. Certainly a bug, and a major, major one from the customer's point of view. Purchasing a two grand machine for my wife, and the very first real user experience she had with it was "I can not put it to sleep, the power button does not work." Oh dear.

    Oh god, I tried it just one more.. and the power button does *not* work any more. Again. Oh dear.

    No, sadly I do not have the same behaviour as you describe. And it looks that I am not the only one, or this topic would not exist.

    Same thing is happening to me (late 2013 Macbook pro.)

     

    My sleep button will work more than once after each reboot, but then it stops working randomly on both my mac keyboard and my wireless keyboard. So I know it is not a hardware issues. Rebooting solves the issue temporarily.

     

    Also since the Sierra update, my mac will sometimes not wake up from sleep. I'm forced to reboot to get anything from my mac.

    Hi jainam2209,

     

    I had problems very similar to yours. I contacted Apple and they suggested a solution that worked for me. Thought it possibly might be helpful for you and others as well.

     

    The first step resets the hardware functions on the Mac.

     

    The second step resets the NVRAM.

     

    RESET SMC

    Shut down the Mac.
    Plug in the power adapter to a power source and to your Mac.
    Using the built-in keyboard, press Shift-Control-Option on the left side of the keyboard, then press the power button at the same time.
    Release all keys, then press the power button again to turn on your Mac

     

     

    RESET NVRAM:

    Shut down your Mac.
    Locate the following keys on the keyboard: Command (), Option, P, and R.
    Turn on your Mac.
    Press and hold the Command-Option-P-R keys immediately after you hear the startup sound or after you press power.
    Hold these keys until the computer restarts and you hear the startup sound for a second time.
    Release the keys.

    Reseting SMC and NVRAM were no solution on my MacBook Pro 2012. The power button stops working after a couple of days. Also have several other problems (Fan running in standby/Network errors with AFP/...)

     

    I guess we have to wit for the next Service Pack, as Sierra is quite unstable on all 3 Macs.

    MacBook 2016, MacBook Pro 15" 2012, MacBook Pro 13" 2010... very sad.

    Same here on a late 2013 iMac.

    Alt-Cmd-Eject works as always but the power button shows no effect until it force-shuts-down the iMac (so it physically works).

    Power Button used to bring the iMac into a sleep on ElCaptain

    I've been having a similar yet different issue and that is, that after I put my mac to sleep it doesn't want to wake up. I have not upgraded to Sierra (as far as I know) so I am not sure what is going on.

    This happened after El Capitan as they changes the behaviour of the Power button from a quick press to a positive press for a few seconds.  Looks like they have changed the behaviour again or they have a critical bug.  Annoying!!!

    Have anybody been provided feedback that this is an actual bug or that they have changed the behaviour of the power button again.  Come on Apple you seem to be dropping the ball on quality, this is not good.  Can somebody from support please reply to confirm if this is an issue

    Exactly the same as PitDark70. I'm on a 27-inch 'Late 2013' iMac, and the power button won't put the iMac to sleep. It used to be that holding it for a short while used to put it to sleep, but now, no response at all. The only function (as reported by others) it has is holding it for around 10 seconds will do an immediate power-down without any prompt.

     

    Alt-Cmd-Eject (which I never knew about - thanks!) works still.

     

    Only noticed this almost exactly 24-hrs after upgrading to Sierra. Seemed to work fine previously, which is a little odd.
