Download of Power Check 0.4 for Mac was on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The software lies within System Tools, more precisely General. We recommend checking the downloaded files with any free antivirus.
From the developer:
UNMAINTAINED.
Problem: iBook, PowerBook or MacBook Pro power cord keeps getting unplugged.
Solution: Audible and Visual alerts from Power Check.
Uses Growl (requires Mac OS X 10.3.9 or later) and Play Sound for extra functionality, but they are not required.
You may want to check out more Mac applications, such as Chaikin Power Tools, Power Manager Pro or Check PrintR Plus, which might be similar to Power Check.
