MacBook Automatically Shutting Down

[atiffarooq]

Occasionally I get a message on my MacBook which says that the system is scheduled to shutdown, and the countdown timer begins from 10 minutes. I can cancel this, but was wondering if anybody knew why it comes up, or how I can disable it? I have noticed it happen maybe 3 or 4 times in 2 months (or so).

Thanks

Sometimes when you install apps you need to make a restart or a shut down. If you don't restart immediately after installing the app, OS X would remind you from time to time to do it.

Have you got software update set up to download and install updates automatically in the background? If you've saved your admin password to the keychain so you don't need to type it in to apply updates, it may be asking for a restart at the end of this process, which might be the first upfront sign your Mac has even been processing and applying updates on your behalf. If it's only every few weeks and not more regularly, that could be it.
