I have a Minecraft server set up on Mac OS X. Whenever the lid on my computer is closed, the Terminal says, Can't keep up! Did the system time change, or is the server overloaded?

The entire server then crashes and no one can play on my server until I wake my computer. What is going on? Can I fix the problem?

I don't know much about Macs, but I'm assuming the computer goes into sleep mode. You probably need to find a way to turn that off when the lid is closed. –  Doozer Blake Feb 1 '13 at 0:08

Apple laptops sleep when the clamshell is closed, suspending any processes, including your Minecraft server.

There are a few ways to keep Mac laptop from sleeping when you close the lid. However, note that the reason the default behaviour is to go to sleep is because the laptops are not engineered to properly deal with the heat of running programs while the lid is closed, so if you do use any of these hacks, be sure to keep a close eye on it to make sure Minecraft doesn't overheat it.

This may also be helpful with putting the display to sleep instead of the computer. –  nysos3 Feb 23 '13 at 22:26

Macs are made in such a way that to save energy and optimize performance whenever a tab is out of focus it is suspended until it is reopened or switched back to, this is probably the case with your minecraft server, you can also get plugins to try and help reduce server load, e.g "Clear Lagg" and " No Lag " There are more plugins at Bukkit.org, that is if your server is Bukkit or spigot.
