You’ll get a pop-up window listing your processor, RAM, serial number, and current operating system. If your Mac has upgradable RAM this window will include a bar with Memory as one of the options.

Final thoughts

Finding out how much RAM you have is as simple as it is important as it’s a potential bottleneck for all sorts of apps, not just games. Google Chrome, for instance, takes up plenty of resources for every tab you have open.

If you want to dive even deeper to see how your Windows computer is using your currently installed RAM, then open the Task Manager, go to the Performance tab, and press on Memory. You’ll see plenty of metrics that will either give you peace of mind or show you how much your currently installed RAM is throttling your performance. Plus, you can see the speed of the RAM here.

For an Apple computer, you’ll open the Activity Monitor app to see the same information. It should by default show memory usage, but if it doesn’t, just press on Memory at the top.
