I had the same problem and I think I spotted a possible cause of the problem. My mouse was called "My Name's mouse" with the apostrophe, maybe that was causing the errors. I have changed the name to avoid using spaces and special characters, now is called just "mymouse" and I don't seem to have the problem anymore.

There is another solution approach using the tool SleepWatcher by Bernhard Baehr. com.apple.discoveryd is just getting unloaded before sleep and loaded again after wake (see post by tseug in "Wake reason: RTC (Alarm) - how to deactivate?"). # author: tseug (see link above) # /Library/LaunchDaemons/de.bernhard-baehr.sleepwatcher.plist <?xml version="1.0" ...

To turn off the power to your "self made USB cooling fan" (nice one) you need to put the mac mini to hibernate mode not to sleep mode. In Terminal (found in Applications -> Utilities) type sudo pmset hibernatemode 1

Solve the problem – Your power cord must be connected to a socket with Earth (Protection Earth typical marked PE). I have had this problem for a long time without solving the problem, besides unplugging a million times. But reading the thing about static electricity... rang a bell for me "EARTH Connection" I was only connected with 2 pin connector (Phase ...

I had the same problem with Linux on Mac, turned out that USB is waking up the system. I disabled the possibility for USB waking up the laptop on Linux. This does not affect the power button or the lid, they still work.

After getting many useful suggestions and none of them solving my problem, I went for a logic board exchange. After that I haven't had another blackout, 1.5 weeks and counting. So, in conclusion what looked like a software problem was probably a faulty GPU on the logic board or something on the board that caused the GPU to fail. Big thanks to Pratika and ...

I have a MacBook Pro 13" A1278 (Mid-2010). I had the same problem. When I closed the lid, the screen remained on wouldn't shut off but I could manually put it to sleep from the Apple menu. Now keep in mind this all happened with no battery in the laptop. I just put in a new battery tonight and voila! Sleep mode works again!! I troubleshooted for hours. No ...

I have had this happen a few times myself. If I was to guess, at the time you closed you lid on your computer you had the power supply hookup and running. After the lid was closed you removed the power plug. Later you open the lid, without the power plug and it was a blank screen. If this is your case, you have two options, unplug first before closing ...

To better understand what is it doing during the sleep and what is consuming your battery: Your system is set to absolute sleep (no activity at all) for 4200 seconds (that is standard) You have the "womp - wake on ethernet magic packet" enabled. Unless you need that, you can disable it with sudo pmset womp 0 You can look up the reason for wake by using ...

Since installing Yosemite I was seeing this behavior. Alistair's answer led me to check System Preferences/Security and Privacy. "Log out after" wasn't in the same place as in his posted picture, in Yosemite it has been moved to the privacy tab where I clicked on the "Advanced" button and then saw that the Yosemite install had set a default logout to happen ...

Is the external monitor always connected to your machine? I'm not sure this will work or if this is a viable solution, but try to set the external monitor as your primary display and report back.

Mountain has an automated solution for your problem. In addition to the battery drain it occasionally happens that the MiniDrive is ejected when the Mac goes into deep sleep. This problem can also be solved with Mountain using the "Remount USB storages" command. This blog article explains you how to use Mountain to solve common issues with the Nifty ...

To keep it awake: try blocking the ambient light sensor with your hand or an object, so iPhone thinks you're holding it against your face. Then remove the obstruction to awaken the phone. This incurs a delay to awaken but might be worth a try. Personally I solved this by simply getting a Jawbone earpiece. They feature excellent built-in noise cancellation ...

Typically for me the issue reproduces consistently in the following steps: 1) Let the Mac run on battery 2) Drain the power completely 3) ...

One solution I have found is using a Yubikey. When the laptop is on the little press button glows. After shutting the lid it turns off after 20 seconds or so. The Nano version also glows from what I can tell, and is small enough to leave in the USB slot permanently.

From what I can tell, if the macbook is plugged in and the external display is attached, it should not go to sleep and work similarly to the Mavericks method. I still have the nvram setting applied and so far so good; the only difference is that I have to keep the lid closed and use USB for keyboard and mouse. Not perfect but close!

Do you mean that you want to know the length of time of the current login session, or the total use for the machine since it left the factory? The latter is not possible because the logs that store that sort of information rotate. The former is sort of possible, but will take you checking the logs frequently. For one, the last command will show recent login ...

I had this exact same problem and it completely befuddled me for a WHILE. Apps to force it to stay awake, like (I assume) caffeine had no effect. Finally while looking at the logs, I saw that what was happening was not that it was going into sleep but rather that it was going into clamshell mode, meaning it was doing what it was supposed to do when one ...
