    Hi guys,

    I had a MacBook Air since 3 days ago, now that I have a rMBP I noticed that the power nap settings are NOT present:

    With other computers you have to do the SMC update and then the option is available.
    With the rMBP, there is no SMC update and the setting is not available.

    Can you guys confirm me this ?

    I thought power nap was coming in Mountain Lion, for the RMBP and new Air?

    Yep, they will probably introduce it in the GM as it is present for the Air's.

    powernap only works with SSD's right?

    so if I take out my HDD and put in a SSD into my macbook pro it should work...or am i wrong?

    no it needs a firmware update for the IEE or whatever its called and its only for the brand new mba and rmbp

    ---

    they took the option of power nap out in the latest update, it was there before

    It only works with 2012 MBA (as in, does not work in 2011 MBAs) and 2012 RMBP.

    So no, i doubt if you replace your spinning disk with SSD that it will work in a regular MBP. I suspect there is additional chipset/firmware smarts to support it.

    You're wrong. Only MBPr and 2012 MBA

    Edit: Beat to the punch.

    so it works with older models too...

    maybe there will be a way to activate the mode like the "trim"-function?

    It works with MacBooks that have built in flash storage, not SSD or HDD. "Power Nap requires a Mac notebook with built-in flash storage. May require a firmware update." - from Apple themselves. It works with the older MacBook airs, from when they were refreshed with to have flash, and the retina MacBook Pros. :rolleyes:

    It's the same BUT as Apple manufacture it's own SSD device, they can flash the firmware (add new functionality), which is not possible with traditional SSD

    Flash storage is soldered directly into the laptop, but a SSD is removable. Flash takes up less space inside the machine. Technically they are the same thing, but Power Nap only works with macbooks that have Flash Storage built right in. :(

    Wrong: the chips are on a small board that can be swiped.
    SSD means Solid State Drive = drive where chips are. The only difference is the format of the "drive".

    It really sucks, it basically makes most of the Macbook pro line unable to get this feature, and surely this is a features pro users would want, not MBA users?
