Sleep has always been flaky under Windows, but it has always been solid under Mac OS X until I "upgraded" to Yosemite. For the first time ever, I am having trouble putting a Mac to sleep. Sometimes it goes to sleep and stays asleep. Other times it wakes up almost immediately. Then I have to shut it down instead.

I find this is the culprit most of the time in non-sleeping or re-waking Macs.

(4,121 posts)I wasn't aware of the 'Allow Bluetooth devices to wake this computer' setting. I have unchecked that box. Thanks for the tip. I'll just have to wait and see if that takes care of my problem.

(51,122 posts)...it's meant to wake it upon a click or tap of the device.
However, sometimes a bluetooth device can spontaneously ping to see if it is 'needed.'
My Jambox bluetooth speaker was guilty of that, so I unchecked the wake box.

Another glitch: sometimes when I type the letters don't appear right away on my screen.

(4,121 posts)even though I followed your advice and unchecked the wake box. Tapping the magic mouse no longer wakes up the computer.
I suspect there's a bug in Yosemite which sometimes causes my computer to wake itself up.

(5,562 posts)I have to watch it and make sure the sleep light starts flashing or it will stay on with the screen black, heating up. Then when I open it I have to restart it. I finally realized that if I touch the mouse or move it wrong that it stays awake/wakes up. If that happens and I lift the lid fast enough it saves me restarting.
Its done the same under the last 2 operating systems, I think I have snow leopard now. I don't know if I have enough room to install yosemite, the hard drive is pretty much full.
