As for what: The message Kernel Assertions: 0x10c=USB,BT-HID,MAGICWAKE says it. Also the ExternalMedia is set to wake it up over your USBbluetooth. connection. So you have a device (BT keyboard) that does that. As for why: You BT track pad wakes up (do you have a Cat?) other BT devices interference, low battery... see this for more. To test do "Allow ...

Maybe the excerpt below can explain. The full article can be found on OS X Daily, Is Your Mac Slow to Wake from Sleep? Try this pmset Workaround: If your MacBook Pro or MacBook Air feels slow to wake from sleep after it’s been sleeping for a while, there may be a fairly simple cause: standby mode. Standby mode allows a Mac to potentially have up to 30 ...

Lets start with a test to find out your settings. copy paste following in your Terminal pmset -g now copy paste results here If you think it is the sensor (unlikely) To test the sensor, take a small (SMALL) magnet like the one on your Fridge, and slowly slide it where the screen and keyboard connect. The sensor is usually at the outer most edge of the ...

I tried asking a similar question on the Apple discussion forum but wasn't allowed. It seems to be a bug. If you log out and log in the settings work as they should, at least they did in my case. I could put my MBP (2010, running Yosemite) to sleep via the menu, close the lid or simply let it go to screen saver and then sleep, let it stand over night and ...

My "perfect solution" for keeping the MacBook lid open but internal screen switched off/only using secondary screen, even with power unplugged(!) using two terminal commands: Enable "screen off": sudo nvram boot-args="niog=1" Disable clamshell in Yosemite: sudo nvram boot-args="iog=0x0" Source: OS X Daily - Disable the Internal Screen on a MacBook Pro ...

I have had the same problem occur to me after a completely new battery was installed in a MacBook Air from late 2011. From 100% I woke up the next day to find the battery at 28%. So I dug up some research I had done and it comes to this command: sudo pmset -a hibernatemode 25 From examining your setting I see yours is not 25 but 3, if you have not found a ...

If you look in the Console log you will find that the WindowServer is having a hard time finding the right protocol for your monitor. Usually that happens when the hardware (cable/converter) connection are not stable, to long or near interference source. From your picture it does look like your cable is to long and to close to the external monitor screen, ...

I have a 2010 MacBook Air, and it was freezing on wake from sleep --- making the thing basically useless. Had to power cycle every time I used it. After much research and fix attempts, here's what worked: - reset PRAM - reset SCM - Use time machine to make a complete backup - Reformat the hard drive - Restore from the latest backup (I did NOT reinstall a ...

It won't stay ejected. When you reboot it'll be reattached. You can, however, fix this. I had to tackle the same problem when my internal drive failed on my iMac. The key is to tell the OS, via /etc/fstab that you no longer want it to mount the drive. To do this you'll need the UUID of the drive. You can get this from Disk Utility. With the UUID in hand ...

I suggest to test and use: Disk Arbitrator. This is a small application interfacing the MacOS X disk access interface. This application may be used in forensic investigation, to protect against unwanted connection of external disks, and to manage very straightforwardly any mounting and eject of internal or external disk (through the Show Disks Window ...

We develop an app called Mountain. The app provides a feature to spin down an ejected internal disk after waking up from sleep again. Enabling "Detach unmounted volumes on wake from sleep" in the advanced preferences should do the job. You can run the current beta version without limitations for a limited time. You can find a link to the beta version here ...

No. I have run mine with external display, for presentation purposes, but you need something like this. Why not just lock the display.

After looking a little further, I found what I was looking for on this page: How can I prevent my Macbook Pro 2011 from going to sleep when I close the lid?

It looks like timing issue between monitor and your Macbook. You might try different cable or just turning monitor off and on with a button (much better than wearing off HDMI socket btw)

The macbook will not go to sleep if an external monitor is connected. What you can do is put your mac in sleep with the following combination: Cmd - option/alt - eject (on newer macs) Cmd - option/alt - power button (on older macs)

I'm afraid that's the appropriate behaviour, and it's called Closed Clamshell or Closed Display mode. Using the Option+Command+Eject shortcut will put the computer to sleep. On the other hand, unplugging the Power Adapter from the MacBook and then closing the lid, will do the trick, too.
