Note : In Mac OS X, RAM is not simply “used” or “free” but can be used in any of three different ways: wired (in use and crucial to keep your Mac running) active (in use now, but may be paged out to disk later) or inactive (not currently in use, and possibly paged out to disk, but also stored in RAM for fast access when needed). If the free RAM drops near zero, consider closing windows, quitting applications, or even restarting your Mac to reduce your dependence on virtual memory. You can recover the used memory simply by quitting the application-but you might never know you have this problem in the first place without monitoring your RAM usage.įor all these reasons, I recommend keeping an eye on how much RAM is currently in use. But sometimes, due to a programming error, an application keeps taking memory and not returning any, so that by doing nothing more than staying open, it constantly chews up more and more RAM. Applications usually ask the system for a certain amount of memory for any given task and then give it back when they’re done with it. You should also be aware of a type of bug known as a memory leak. This slows everything on your Mac way down, and it also uses up disk space. Even so, if you have enough applications open at once, and if they require enough memory to perform their respective tasks, you can get to a point where the data swapping occurs constantly.
