Part 1. What is Memory Usage?

Memory usage is the core of the device wherein it stores all the codes, instructions, and all application operations on the entire Mac.

When the memory is starting to get full, it slows down and causes latencies on certain Mac operations and software. This is a very disgusting state where you cannot fully use your Mac even you need it the most.

So what can you do to resolve this slowing down or memory full issue? Clean-up; a thorough clean-up is the best thing to do to remove apps no longer in use and reduce the memory usage.

Part 2. How to Tell Memory Usage on Mac?

Today we will be discussing 2 effective ways on how to tell memory usage on Mac. Both are effective and reliable but only one has more advanced tools. Check it out:

Method 1: Using Activity Monitor.

The activity monitor shows the entire processes that are running on your Mac. This tool lets you manage and monitor the overall health status of your device.

Launch Activity Monitor on your Mac (Go to Applications > Utilities)

Find and click Real Mem Column among the headers in the middle. By clicking this area you will find all the space eaters on your device. You can determine which apps are consuming much from your memory space.

Now click on the System Memory. From here you can see the ‘Free’ space left on your Mac as well as the ‘Used’ memory. Your device must have at least 10% free and available memory to sustain and maintain daily tasks.

If you want to see the real-time memory to monitor it, on the Dock icon, right-click and choose Dock icon and then select Show Memory Usage.

Once you have the memory usage monitored you can now be aware of how much apps you can download and force yourself to delete unnecessary software that hogs the space.

Part 3. What are the Ways to Reduce Memory Usage on Mac?

If you wonder what the ways are to reduce memory usage on Mac, here are the important things you need to do to keep it at optimum performance.

Way 1: Trim Dashboard Widget.

It’s good to have one place for all the apps you frequently use, however, is it really necessary? Dashboard widgets can take a lot of memory usage and may affect the performance of the system.

It is better to review and assess if there is really a need for all of them to be present on your Dashboard. Otherwise, you can remove them and use only the more important features.

Way 2: Turn off Resume.

Resume automatically re-launches the applications in the state you left them. If you are fond of closing the browser entirely without closing each tab then Resume will take note of this and display the same tabs just exactly how you left them.

By doing this, it slowly clogs up memory usage because it stores a lot of browser caches. To disable Resume, follow these:

Open System Preferences

Click General

Tick the box for Close windows when quitting an app

Another way to disable Resume is via web browser itself. Just simply enter these codes in the terminal:


defaults write NSQuitAlwaysKeepsWindows -bool false


defaults write NSQuitAlwaysKeepsWindows -bool false

To enable Resume, simply change the word false into true.

Way 3: Update MacOS.

If you are still unable to move on from your macOS then I guess it is high time to give up. Newer versions may include fixes and features that can boost and enhance memory.

If you will not upgrade then you might really get yourself into the turtle race.
