Many Mac users don’t know how much exactly RAM they have on their Macs and how much of this RAM is currently used. However, this knowledge is useful if you don’t want your Mac to eventually run slow. So real-time monitoring of your RAM is pretty useful in this case, just to prevent potential problems from happening.
To monitor your Mac’s memory, you can use either the built-in Mac OS X tool, specifically Activity Monitor, or install a third-party app, such as MemoryKeeper.
Activity Monitor may seem a bit complicated to use, but we hope that our guidelines will help you. So, to monitor your Mac’s memory with the Activity Monitor application:
- Click Applications > Utilities > Activity Monitor.
- Sort the active processes by memory usage by clicking the Real Mem column header. As a result, you will see which applications are consuming the most memory on your Mac.
- Click System Memory to see how much free memory is available at the moment. If you have not much free memory, you should either quit some applications or use a third-party app, such as MemoryKeeper, to free up the memory.
- To display memory usage in real time, right-click the Dock icon of the Activity Monitor and select the Show Memory Usage menu item. As a result, the Dock icon will be show as a pie chart that will show how memory is allocated on your Mac.
Many third-party memory optimization apps show the amount of consumed and free memory directly after you open them. Moreover, you can instantly free up memory with just a couple of clicks and bring your Mac back to an almost brand new state. App reviews can show how these apps work; for example, you can read the MemoryKeeper reviews on the AppStore that will help you decide whether you need such an app. The advantage is that the Activity Monitor cannot free up your Mac’s memory, whereas apps such as MemoryKeeper can, so it’s up to you to decide.
