Recently I experiment a lot with disabling memory compression in Mavericks and I had clearly reproducible problems with hibernating to disk. 1) Enable memory compression and using an hibernate mode that writes to disk works without problems vm_compressor=4 + hibernatemode=3(RAM powered+sleepimage) or 25(only sleepimage) -> no problem when restored ...

I ran into this issue as well on my iMac, but since I have dev servers running in a VM all the time, I don't put my machine to sleep, so for me, the problem was fixed by how I am using my Mac. However, I also have a MBP where this problem would crop up every now and then; especially when the MBP would go to sleep. However, you may wish to try enabling and ...

I had the same problem with TL-WPA4220 - the powerline wifi didn't seem to be passing multicast traffic to and from my Macbook Air (including Sonos, AirPlay to Apple TV, Dropbox LAN sync, and plain ping 192.168.1.255). I tried reducing the TL-WPA4220 from 40MHz to 20MHz, and I don't know why, but everything seems to be working now: As part of basic RF ...

It appears to be a common issue until ~ OS X 10.10.3. I'd say your only option is to upgrade when it comes out or do a clean install of 10.10.2 and see if that works out for you. I can understand that you'd rather not do a clean install but it does actually solve a lot most of the time.

You can use a third party tool like Power Manager to make your Mac sleep after a period of inactivity. Unlike OS X's Energy Saver, Power Manager can put your unused Mac to sleep even when an application or process has requested otherwise. Disclaimer: I wrote Power Manager and can answer comments about how it works.

That log shows few problems.

Won't fix your issue, but, anecdotally… My Mac has been running 24/7 since 2008, never sleeping & only ever rebooting/shutting down for OS updates/hardware clean etc. No issues so far. So I'd say, yes, it's perfectly safe to leave it awake, so long as it has adequate cooling.

Bad news? Your GPU is faulty. Good news? Apple launched a repair program to fix MacBook Pro machines sold between February 2011 and February 2013 that have problems with distorted video, no video, or unexpected system restarts. (taken from macrumors.com)

I had a similar issue with mine (mid-2011 MBP running Yosemite), where not only would it go to sleep and not wake up, but it would reboot and freeze midway through the startup process. It would take several hard restarts to get back to a login screen. After awhile, I came across a thread on the JAMF Forums with users having similar issues. I found that this ...

Another option to try is disabling Wake for Network Access inside of System Preferences -> Energy Saver. We have this problem at work and doing that + renaming it back usually seems to hold the name in place

Make sure all the ports don't have any dust In them and that all the cords work

I don't believe it is a hardware issue because everything seems to work fine on Bootcamp. The only variable now is the OS. What happens if you unplug the adapter from the MacMini then plug it back in? Does it work?
