Well none of this worked for me. This is what I did before I found the issue. After the computer would come back on after sleep (macbook pro mavericks, screaming computer with 8gigs ram, retina) the right side monitor, out of the 2 monitors I have plugged in by VGA->DVI, continued to be reset from 1600x900 to 800x600. I would: Unplug the DVI port from ...

I'm no expert either, but I know that if left on sleep/having the lid down but the power on can build up enough heat (if on long enough) to catch on fire. iOS devices are different though, as they do not release heat. If you need to charge the MacBook quickly, shut it off completely as this increases charging efficiency.

Eject is only temporary, once restating the computer will read the disk again if it is still plugged in or you freshly plug it in. So use the unmount in disk utility that is permanent till you mount it again. I forgot, also disable the Spotlight search for that disk, so it wont spin any more.

Whether to shut down or keeping it in sleep state (by closing the lid) depends on the time usage in between. The short answer is: If you use it daily, enter sleep mode is recommended. If you rarely use it, shut it down. So let‘s see the difference between each option. We’ll start with this statement: An interesting opinion - cannot find the link for ...

I'm no expert at all, but I can tell you that I regularly keep my Mabook Pro 2008, MacBook Air 2012 and Mac Pro 2008 powered on / asleep for weeks if not months at a time without rebooting. When their charge drops to around 20%, I plug them in. The machines don't noticeably slow down over time like PCs do, so I only reboot if installing something, or if I ...

I do not claim to provide an answer - as much as a step-by-step clarification of the question (by re-edits), which in the end might sum up to an answer. I see here the idea that: waiting for an OS X Update or Security Update is generally a sufficient time between reboots. Also, that shutting down is useful, because system temp, memory, swap, and cache ...

according to apple: "Standard Maintenance For proper maintenance of a lithium-based battery, it’s important to keep the electrons in it moving occasionally. Apple does not recommend leaving your portable plugged in all the time . An ideal use would be a commuter who uses her notebook on the train, then plugs it in at the office to charge. ...

Wimoweh $$ will automatically keep your mac awake when user selectable processes are running and will control the display sleeping (or not) as well.

The default sleep mode used by Mac laptops is a hybrid between traditional sleep mode (suspend to RAM) and hibernation (suspend to disk): the contents of the RAM are saved to the disk, but the RAM is kept powered as well. Desktop Macs use traditional sleep mode (suspend to RAM) by default. See man pmset: SAFE SLEEP ARGUMENTS hibernatemode takes a ...

I have had good experiences with SmartSleep: http://www.jinx.de/SmartSleep.html For instance it will go to hibernation when the battery level goes below a certain percentage.

You can do this with SleepWatcher, an app that lets you… execute a Unix command when the Mac or the display of the Mac … wakes up Such a command to open an app could be: open /Applications/Safari.app

Go into System Preferences > Sharing and turn off Internet Sharing and File Sharing. You can run pmset -g assertions again in terminal and you will see the 1 is gone that counts. After restarting your computer it will go to sleep while plugged in now.

See where System Preferences -> Energy Saver says: Wake for Network Access? If your mac is asleep it can still be accessed via Wi-Fi, and woken up. Power Nap wakes up and connects to services and then disconnects, going into Bonjour Sleep Proxy mode for being woken up again via Wi-Fi. http://support.apple.com/kb/HT5963 ...

try pulling the following files to see if it makes any difference-- /library/preferences/com.apple.powermanagement.plist /library/preferences/com.apple.autowake.plist ~/library/preferences/com.apple.systemuiserver.plist as well, you could try resetting the pmu. http://docs.info.apple.com/article.html?artnum=300574 and you could boot to the install disk and ...

I think you are trying to find out what is draining the battery during the sleep. Macs are designed to use the sleep time to do some house cleaning and chores. The first 4 hours autopoweroffdelay 14400 seconds it will do nothing (energy saving regulations EC), then it will wake up to do its stuff. But based on this study under "normal" conditions ...

However, that didn't work for me on a circa 2008 iMac running 10.9.1 or a late 2010 MacBook Air running 10.9.2. I'm not sure if this has something to do with ...

Contrary to my belief this is most probably a software issue since I cannot reproduce the problem after updating to the most recent version (10.9.2) of OSX.

Actually thanks for your detailed report one can see it is the application Boom preventing the sleep mode. Try one of the following by updating the app Boom to 1.8.1, or disable it to test. The 1.8.1 has some fixes that might help: --- Audio clipping(cutting out) issue is now fixed. --- Kernel task consumption issue has been fixed. Now it functions the ...

The issue is related to SafeSleep or SmartSleep on the OS. This system puts all your current memory (your RAM) onto the disk, so that it can power down the RAM, save energy, and keep the current working state of your computer, even if you ran out of battery power, changed batteries, etc. Problem is, it’s slow. And buggy. Often when waking from sleep by ...

Goto System Preferences -> Energy Saver -> Check "Prevent computer from sleeping automatically when the display is off" The options may be slightly different depending on what generation macbook you have, but this should help point you to the right place. :)
