Magnus Lundhold, creator of CoolBook, a battery testing and configuration utility for Intel-based MacBook and MacBook Pro laptops, has released a beta version of a dynamic frequency stepping utility called CoolBook Tester.
Once installed, CoolBook Tester can experiment with different parameters such as voltage and temperature settigns. Users can easily install and uninstall the new feature and CoolBook Tester can help improve the detection of AC/DC power modes.
The CoolBook Tester beta is a 159 kilobyte download and requires Mac OS X 10.4 or later and an Intel-based Macintosh to run.
A license for CoolBook, Lundholm’s main program, retails for $10.
