Apple's About This Mac window groups unknown memory with the "system bar". The result is that RAM Charger applications, which grow and shrink dynamically in memory usage, would not show their "expansion". Instead, Apple's About This Mac window displayed the dynamic changes in the "system bar". More About This Mac understands RAM Charged applications, and shows them as they grow and shrink dynamically in memory usage. As a result, "More About This Mac [Lite]" was developed to supplement RAM Charger, and a free version is provided with all copies of RAM Charger. More About This Mac works with all versions of RAM Charger, and may be installed on any computer running any version of RAM Charger, as well as on any machine without RAM Charger.
