This process technically frees up RAM, but only in the sense that squeezing a sponge down on a flat surface frees up water-absorbing capability. After the cleaner program grabs as much memory as it can from the system, it then relinquishes the memory it's been using.

They typically start a routine that imposes a high RAM demand on the system, which forces the OS to signal other programs to free up memory and to write as much unused data as it can to the hard drive. Generally, as you load more programs, the system will write transfer more program data from RAM to the hard drive, thereby freeing up RAM for use elsewhere. As a result, there is room for the program to reduce its memory footprint and still work in a more constrained workspace if the demand for system memory increases. When a program loads and performs its functions, it will ask the OS to reserve RAM space for active use-not all of which the program needs right away. In OS X, the system manages a program's RAM. In fact, though, active programs may soon encroach on this wedge. After running a RAM cleaner, you'd think the large green wedge means you have a large amount of RAM to use. While this technically means the system now has more free memory-which to most people suggests the system now has more memory to use-most of the time this is not the case. Afterward, your Activity Monitor typically shows a larger green segment in its memory-usage pie chart. Click it and your system will slow down quite significantly for a few moments. These tools typically feature a relatively simple interface dominated by a button marked "Clean" or something similar.

But there are also a bunch of third-party memory-cleaning tools that claim to clean up your memory without all that bothersome mucking about-tools such as MemoryFree 2, iCleanMemory, FreeMemory, MemoryFreer, Memory Cleaner, Memory Cleaner Pro, MemoryScope, FreeMemory Pro, Flush Memory, and so on (there are many, available via or the Mac App Store). The straightforward way to do this is to quit programs and close open files. So if your system begins to slow down, freeing up RAM can speed things up. When you run low on memory, though, this process may encroach on active computing tasks, which will significantly slow them down. The system continuously manages and optimizes memory by writing unused contents to disk. So if your computer begins to slow down, one of the first things you should check is whether your system is running out of memory. Your computer's RAM is a fast, temporary workspace for active tasks. But think twice before taking their claims at face value. There's no shortage of programs that promise to boost your computer's performance by clearing its memory.
