sleepwalking

[LittlePaul]

Hi,
my Mac Pro sleepwalking on the night.
Every night for 2 times it's power on for few seconds and after return on sleep.
It's occurs with 10.9 and now with 10.10
why?

Thank's

It is the (new in 10.10) discoveryd doing it's once-every-two-hours mdns sleep proxy registration thing. There are few workarounds for that if you Google around - my favourite one is just to disable discoveryd launch item on suspend, and add it back on resume.

For some pointers:
