I use a MacBook with 2 Go of RAM. iStats Menu 3 shows me that I have 500 Mb of "inactive memory". When my "disponible memory" (it does not include this inactive memory) is very low, the Mac starts to be slow.

Is there a way to have the Mac use this inactive memory? What is it exactly?

I have also wondered this but a quick Google found this:

Inactive memory is memory that has previously been used to run an application. OSX keeps certain things in memory just in case you launch the application again, so that it'll launch quicker. However, this inactive memory can be released to a new app as needed.
