Dropbox sync during the night

I had a similar problem under Yosemite, but I think earlier versions of Mac OS X would behave similarly.

To fix the problem: go to Settings->Energy Saver and check the following:

• Enable Power Nap
• Wake for network access
• Prevent computer from sleeping automatically when display is off

This will allow you to allow your monitor to turn off, and your sync with Dropbox to continue uninterrupted.

I normally put the sliders to never and then leave the lid open but if you turn the screen brightness all the way down it will turn the screen off. That way Dropbox can sync all night but your screen will be off so won't be damaged.

Dean V: thank you, this seems a good option

Mark Mc: Of course I left the Mac on and it sleeps automatically. If it cannot sleep to sync, what is the best way to do that? I could go to Preferences > Energy Saver > put the slider to Never. But it does not seem to be a good thing to leave so many hours the computer with the same screen? what is the right way to do that?

Rolf: thank you for de detail. Makes sense
