I think I found the easiest way ever in my whole history of using osx to free up ram. Well, of course I am talking about using a free app. 😉

Here it is. It’s rightfully called FreeMemory and you can download it from the Mac App Store.

With it, you no longer need to manually check your Activity Monitor, close apps, relaunch… Once you launch the app, it will display your current free memory amount on your top bar. When you need to free up some memory, just click on the app on the top bar, then click “free memory”. That’s it!

Hope you find it useful as well!
