Apple Releases Firmware to Activate PowerNap on 2011 MacBook Airs

You might want to consider the energy required to spin up a disk.

Is there a real reason for this or is it just BS like many of the features left off older iphones? I can tolerate it on a mobile device but if they start leaving key features off of my computer for no reason (because lets face it even a core 2 duo has enough power to do any of these features) my 2010 imac will be my last mac

I'm all out of cheese.
 
Does PowerNap work if you are not signed into the MAS? Anyone know the answer to this.
 
whoa whoa whoa. I can do without PowerNap. But no Airplay? That was THE one reason for me upgrading. WTF.

I'm sure in a month someone will figure out a hack. Totally unnecessary for them to snub a computer that could easily do AirPlay.

I have a sandy bridge MacBook Pro with a SSD and it's not supported. And my SSD doesn't exactly require massive amounts of energy compared to the retina MacBook Pro or the MacBook Air.

It may use a different chipset or firmware. Again, there are lots of Windows notebooks with SSDs, but they are touting this feature only for Ultrabooks.

I was even more confused by this when I typed Power Nap into the search box and it highlighted Energy Saver but there was no option in there! All fixed now :)

Haha yea, that's how I found it and there was no option. I had to check for the update a few times but now it's there.

I am not. On a side note let's get Tim cook fired he's screwing up what jobs built. Apple is going to really regret this year if iphone 5 disipoints.

You do realize he probably was still all around for this when it was in the works as this point....also for all the others bitching. Both power nap and airplay require help from intel sandy bridge cpu's

Ya he was around but not for the end, all the fine tuning and etc.

regardless all the issues people are bitching about are actual hard limitations... do some research on these features a little more in depth. It's not like apple purposely is not including all features possible. (at least this time)

No, but they can create software workarounds. They could easily have written something similar to AirParrot and we'd all be happy then.

As for powernap, that too could be a software tweak.

At this point, it's water under the sandy bridge for me. I'm fine with Notifications and Safari tab sharing with my iPhone. Oh wait....
 
Energy consumption

I"m really curious to know how much energy a laptop will consume using Power Nap. I understand solid state drives were key to making this feasible. I'm guessing the biggest draw would just be the wifi connection. Maybe they minimize this by only powering on and checking for updates periodically. Either way, I'm curious to know how they've implemented this and what kind of numbers we'll see. I'm not freaking out about this at all, I'm sure you can disable it if you want, and I doubt it's a huge power draw, but it does beg the question given how much attention we pay to standby power these days.
 
Isn't the SSD found in the airs (and presumably the rMBP) a PCIe SSD? I could've sworn I read a few articles on here that indicated that was the case. Could that be why powernap is only being activated on those models?
