Night Night is a network activity monitoring app that will put your Mac to sleep when your network activity drops below a user defined threshold of network speed and/or inactive time.
So the obvious benefit is you could start a late-night file download with an FTP, File Sharing, or any download client, knowing your Mac would sleep when the download was complete.
Better yet, Night Night will work with any app on your Mac because it monitors network traffic from the operating system itself rather than just individual programs.
NOTE: Night Night can only be purchased via the Mac App Store (the buy link redirects you to its App Store page). To purchase/download applications via the App Store an Apple account is required.
Here are some key features of "Night Night":
· There???s also an option to have Night Night start monitoring your network traffic only after your network data rate exceeds the speed limit. This is useful if you???re trying to download from a busy server: Night Night waits until your Internet program makes a connection and begins to download the desired file, and only then waits until that download completes to put your Mac to sleep. A sub-setting here lets you designate a time limit for giving up on the connection; for example, if the data-transfer rate doesn???t pass the speed limit after 20 minutes, Night Night can immediately put your Mac to sleep.
· There are options to choose which network ports are monitored such as Ethernet, AirPort, and FireWire.
· The user also has the option to monitor downloads, uploads, or a combined monitoring of uploads + downloads.
· Miscellaneous settings include: Start Activated, Keep Active After Sleep, and Before Sleep Quit the App.
