macOS Sierra - hold down power button to enter sleep mode

Definitely! I don't know why Apple isn't answering to that topic any more.

Btw. the terminal command wasn't helpful. After two sleeps its broken again 😉 .

So please Apple - fix that soon!

I came across this problem too. I contacted Apple support and he told me to do this:

Power on the computer and immediately hold down the Command, Option(Alt), P, and R keys until you hear the startup chime twice. You'll then log in as normal and that fixed it for me. Hope it does the same for you!

Hey, that is a Cache Clear (one of the Caches) but it was not helpful. After two sleeps its broken again. I'm also recognized that my mac is awaking in the night ..and it's not falling into sleep again. So looks like the Sleep Mode is broken at all.

Mine still works fine and I used it all day today. You think it's a difference between a Macbook Pro and Macbook Air? I'm just trying to figure out why it worked for me and not for you.

Please get back to us if it worked for a week, or more..

For me, the mentioned fix with a command line works for some 5 days now. Hope it stays ok.

Does somebody has an idea, how I could get support from apple ? (hardware support is over...but I thinks its just an software issue)

I used the chat option since I was at work and couldn't troubleshoot over the phone.

same issue

It stopped working as of today, meaning the solution only worked for a couple days. I'll need to contact Apple support again to see what else they can suggest. Honestly, they should stop playing around with things here; everything was perfectly fine before with Capitan and other OS. As they say, if it ain't broke don't fix it. Hope they don't become the next Microsoft.

Same for me, yesterday I talked with a very good apple support guy. We started my MacBook from Safe Mode (and it worked). In the normal Mode it worked too...for 15mins 😉 after that it was broken again. My MacBook also still awakes by (getting a Mail or iMessages) and normally its falling into sleep again (Capitan),- that fails too. So currently I need to switch off the WiFi at night 😀 - thats very unserious! 😀😟

Next answer from the official Apple Support "we currently don't have a solution for that, we are hoping that the engineers will fix that Bug in with the next Update". One last try would be "restart the computer, while its booting, hold CMD+R to geht into the xyz Menu"..."there you need to select the second option - reinstall the OS", this should fix some problems. But I won't try that, because I don't know what will be overridden..maybe some of my settings and tools will crash.. I'm a bit shocked that nobody of the apple care knows about that Bug - and a real solution. 😕

Hello !

Please go to system preferences & in energy saver make sure computer sleep slider should not be zero .

Screen shots for reference , click on restore defaults , the slider will automatically get set .

Thanks !

Hey tybg, thanks for your try. But I already did that. Generally I don't want that my mac is awaking for doing things...so I din't checked that box. (but it's doing it nevertheless). But the general problem is the not working sleep function by holding the power key for 2-3 sec.

Please hold for 1.5 seconds while your Mac is awake to display a dialog asking if you want to restart, sleep, or shut down. If you don't want to wait 1.5 seconds, press Control–Power button or Control–Media Eject .

Thanks !

Nope, this is also not coming. Default behaviour is 2-3sec -> sleep mode. 10sec hard-shutdown

on some configurations the dialog asks you what to do. But the topic is about getting back the 2-3 sec behaviour.

CMD+POWER is no solution for that case where you have an external (logitech) all in one keyboard(with pad) ...there you also have the power button...and don't want to push more than one key. Again, that was function which was implemented sind a loooooong time. And now its broken, its a bug, and needs to be fixed by apple 🙂
