Choosing a Free Memory Setting

OSBooster can't give all remaining free memory to an application. This is because for every application that launches, other resources must be loaded by the system that are not placed into the applications memory space.

QuickTime is a good example of a system resource that normally has a very slight effect on free memory. However, when an application plays a movie with QuickTime, as much as an additional megabyte of memory may be needed by the system. Other resources, such as shared libraries, Navigation Services or Networking all have the same effect. They need certain amounts of free memory in order to load and co-operate with applications.

For this reason, OSBooster chooses to leave varying amounts of Free Memory when launching an application. Many applications are 'known' to OSBooster and OSBooster chooses a specific value that we have found suitable. For other applications, OSBooster uses a default value.

Since we cannot possibly prepare a specific value for every single Macintosh application, it may be that the default value is too small for some application - and you find that application fails to function normally or crashes. Some applications may not crash until you quit them. In either case, this is a symptom of having too small a Free Memory setting. You should increase the setting until the application behaves normally.

Likewise some applications may function well with a smaller Free Memory setting than the default value. You are welcome to experiment with this setting, but you should do so in the knowledge that you may cause that application to crash. Don't worry though, OSBooster does a good job of cleaning up after itself and you should find that your Macintosh will restart normally.
