I know this thread is a bit old but upon searching for possible fixes for my mid year 2012 Mac running Mavericks, this is the first thread I found that may have a fix I could try. I just need help deciphering what you guys tried here, maybe adding that code to preferences. I dont have the file listed in the OP's note. I was able to find one file I could try to edit under:
Library > Preferences > systemconfiguration > preferences.plist
Is that the right file to try to add that code? And if so, where do I put it? At the bottom once the rest of the codes are done? I see about 5 </dict> in a row before the finale note of </plist>.
I don't see any words about kernel flags or darkwake already in this doc. If this isn't the right doc, what else should I look for? It looks editable on my system with the text edit s/w that came with the computer.
The challenge I've had is:
My computer won't up easily after 8-10 hours of sleep, even though the system settings look normal.
When I used to open my 2010 mac computer, it was up and running and on the internet in about 5 seconds.
This newer computer, even though it's an older model 2012, it was bought new in Dec 2014. And has done this problem since right out of the box. This 2012 computer instead either opens to a black screen with the keyboard light off, it takes touches to mouse or space bar or esc key to eventually get it to wake up. Or I've had to open and close the laptop a time or two to get it to wake up. Sometimes it wakes up to a faded screen and a progress bar in white like I used to see on old Windows computers waking up.
Will adding that code you guys have here potentially stop this from happening?
Not sure if this is related or not, but if it's been over 5 hours since I had turned it on or woken it up, when I open the laptop, the CD / DVD drive makes the eject noise. If I unplug the computer instead of opening the screen, it also makes that noise. Only happens if the computer has been off for a while. Not during the day when I open and close at shorter intervals.
Already been to Apple Care Genius Bar, and they couldn't figure it out while I was there because it can't duplicate problem in store since there's not enough hours of waiting to open the computer screen up. They did remove the battery and try a reset on the sleep system, but upon getting it home that didn't fix it. For them to look at it it has to stay with them for a couple of days. Trying to avoid that if this here is a fix. Thoughts?
