Mac starts up automatically My Mac OS X El Capitan seems to start up on its own, out of the blue. Even though I have powered it off. It starts at random.

I do not have any startup program or anything scheduled for this to happen. Any insights? Is this a security risk or effect?
You may have your Mac setup to start automatically. To check follow these steps:


From the Apple menu, choose System Preferences
Select Energy Saver
Click on the Schedule button 
Check the options to see if this is what's causing your problem 
Make any changes you need to
Click OK


Hope this helps!
