Q: rMBP goes to sleep instead of power nap
Hello,
when I close the lid of my 2012 rMPB it goes to sleep instead of going to power nap mode.
System logs says:
14.10.14 22:05:47,000 kernel[0]: Previous Sleep Cause: 5
(5 = shutdown (user initiated thru system, ie, shutdown from apple menu or shell))
I have power nap activated for battery and cord, did the SMC reset and battery is charged 100 %.
OS is Mavericks with all updates.
Any idea why I'm having this problem?
Thank you!
MacBook Pro (Retina, Mid 2012), OS X Mavericks (10.9.5)

When you close the lid on a portable Mac, it enters sleep mode, not Power Nap. The sleep mode you're describing is normal.
Some time after it enters sleep mode, Power Nap will wake it periodically to do its tasks, upon the completion of which it re-enters sleep mode. The cycle repeats until its battery reaches a certain charge state or you wake it. If you want to examine wake events including Power Nap, you have to filter system logs for some other parameter such as "wake".
I'm not 100% certain but I believe an NVRAM reset will reset sleep mode parameters if they have been modified for whatever reason. It may also be justified if you have reason to suspect Power Nap is not working as you think it should. I doubt it's related to the Wi-Fi reconnection problem.
