Possibly stupid question re: energy saving prefs on new rMBP.

[yegon]

Took delivery of my 15" rMBP earlier, it's tremendous.

Weirdly though, I can't seem to set how long before it sleeps in the Energy Saver preference pane. There simply isn't the option to do it, only "Automatic graphics switching" check box at the top, then Battery/Power Adaptor selection, then the "Turn the display off after" setting.

Is this deliberate? Is this a "feature" as it's so battery efficient, or is it located elsewhere? I'm coming from an old mba, so this is new to me....

Move the slider for computer or display sleep.

I don't quite follow. Here's a screenshot;

I also noticed this on my 2013 Haswell rMBP. It does appear that Apple has removed the ability to set how long until your machine sleeps. Perhaps they are relying on that light detection thing from the ambient light sensors to delay sleeping.

Wow thats strange, Where did the computer sleep slider go.

Quu is right, Read this.

Thanks for the responses, at least I know I'm not going mad!

I wondered whether it was related to restoring from a TM backup of my old mba (running Mavericks) but it seems not.

Strange, hmm.

And in other news...OOH THAT RESOLUTION! I could get used to this

Sleep slider is also gone from my settings as well.

I think its all based on the light sensor now. If it senses you infront of the machine it wont sleep. If you are not around it'll sleep normally - at least, thats how it should work!

rMBP 2013 owners, What happens if you uncheck Automatically adjust brightness in Displays.
That turns the sensor off, how would it work then?

No change, still just the Display slider.

Thanks.
