Memory Magic 1.2

Memory Magic monitors your Mac's memory usage and transparently performs optimizations aimed at freeing/relocating memory.
Secondly it features history graphs to help you visualize both physical and virtual memory usage patterns and a manual "Force memory recovery" mode.
It is similar to the built-in "purge" command in that it gets rid of some unused memory but that is where the similarities end, Memory Magic weights a lot of factors like what applications are running, what applications were recently terminated, the memory distribution and swap usage.
Great care has been taken to make it as non-intrusive as possible, it uses very few memory and cpu cycles, it will not attempt optimizations when cpu load is too high or when memory operations would only slow down the system.
Memory Magic is fully retina display compatible and has a very clean and easy to use interface that is aimed to be natural to navigate and emphasize simplicity.
