Briksoftware (http://briksoftware.com) has announced UnPlugged 3 for Mac OS X. It’s an update of the power-supply notification system that allows users to know when the power supply of their MacBook changes.
UnPlugged 3 adds compatibility for the Notification Center and adds the ability to have different frequencies of battery charge notifications when the battery charge is low and when it is high. The update also provides localization support for English, German, Italian, Russian and Simplified Chinese.
UnPlugged requires OS X 10.6.6 or later. It costs US$5.99 and is available exclusively through the Mac App Store in the Productivity category (http://tinyurl.com/bpv3lpb).
