Is it 11" or 13" ? Probably doesn't make any difference, but just wanted to check as it definetly doesn't work on my 11"



Left it plugged in overnight - no Time Machine backups have been done. In fact, if I close the lid during backup and open after an hour or so, it's resuming from the point where it was when I closed the lid. Also, I can see that wireless is reconnecting when I open the lid even after few minutes.

Find my mac is also unavailable.



Strangely, I can't even turn power nap off - the check box is always ticked when I open power saver options! Both, on AC and battery.



Anyone know how to roll back to previous SMC Firmware? I'm worried that this will break something eventually.
