Next time, install FastAndSlow with 1-click

Learn how MacUpdate Desktop can install apps on MacUpdate with the simple click of the Install apps with MacUpdate Desktop icon. Plus, keep all your apps updated.

FastAndSlow is a MenuExtra addition that adds the ability to switch the Powerbook/iBook CPU/iMac G5 processor performance (in the Energy Saver settings) from the menubar.

You can select between "fast" , "slow" and "Automatic" (if your computer supports this setting). It is useful for example when your Mac becomes too hot and the fan starts. Using the slow setting it doesn't happen and will reduce battery consumption.

What's New

Version 1.3.1:
  • Added French localization.
  • Added "Read me first - francais" documentation.
  • Fixed a bug on Tiger 10.4 that used to prevent the FastAndSlow menu extra from displaying the current settings correctly when switching to a default power profile using the Energy Saver preference pane.
    (Thanks to Byron Shaheen with MacPRO for software testing and for the French localization and documentation).


Mac OS X 10.1 or later, Powerbook,iBook or iMac G5.
