You want to increase the power of your Mac? At very low cost? You want to increase by 20% to 30% the speed of your applications without spending money in new hardware? You want to automatically always make the most of the power of your CPU to the foreground application you are using? Then CPU Speed Accelerator is what you need. CPU Speed Accelerator allows you to drastically increase the CPU allocated to your foreground applications to make the most of the power of your Mac. It can increase by up to 30% the power of your Mac. It automatically detects the foreground application you are using. It redirects unused processing power of your CPU to the foreground application. You can set the percentage of acceleration between 0% and 100%. It tells the Process Manager of the UNIX layer of Mac OS X to always assign the maximum priority to the foreground application. It appears in the right side of the menu bar. It doesn't need any installation which makes it very easy to use. It is absolutely not harmful at all for you Mac and your Applications, since it does not modify anything on your Mac but just optimizes its processing power, only when the application is running. It is available in Catalan, Croatian, Czech, Danish, Dutch, English, Finnish, French, German, Greek, Hungarian, Italian, Japanese, Korean, Latvian, Norwegian, Polish, Portuguese, Romanian, Russian, Simplified Chinese, Slovenian, Spanish, Swedish, Traditional Chinese, Turkish and many other languages.
