Free Memory For Mac

On Linux, I often use the free command to see the current amount of free and used memory in the system. For example: $ free total used free shared buffers cached Mem: 729 0 388 -/+ buffers/cache: 4284 Swap: 81264428 It does not seem to exist when I enter free in Mac OS X's Terminal.

Optimized Storage in macOS Sierra and later* can save space by storing your content in iCloud and making it available on demand. When storage space is needed, files, photos, movies, email attachments, and other files that you seldom use are stored in iCloud automatically. Each file stays right where you last saved it, and downloads when you open it. Files that you’ve used recently remain on your Mac, along with optimized versions of your photos.

One of the most common problems that Mac users encounter is low computer memory. Over time, even the most powerful computer will get cluttered with apps, files, extensions , and processes that are too much to handle. To get everything back to normal (because every byte matters), you need to declutter your Mac by cleaning up the mess and removing unnecessary stuff that consumes your computer’s memory.

So when your computer is slowing down, you are likely to notice a “Your system has run out of application memory” message, many of your apps are crashing, or you keep on seeing a lot of spinning rainbow wheels. All these mean your computer is probably low on memory or RAM.

Free Memory For Mac

This article will show you how to free up memory on a Mac and other tips to optimize your machine.

What Is RAM?

RAM stands for Random Access Memory and it is one of the most important components of computers and laptops. It is where the computer stores data before being processed. It is a form of volatile memory, where the data is available only when the device is powered on, and everything gets deleted when it is shut down.

Most Macs are equipped with 8GB RAM, but older versions only have 4GB RAM. This is enough if you’re not using RAM-hungry apps, but even then, you’ll still most probably run into memory-related problems in the long run. If you notice that your Mac is taking ages to load or your applications are often crashing, you need to do something to manage your computer’s memory and give it some breathing space.

However, upgrading your Mac’s RAM is more complicated than it sounds. Not all Macs have upgradeable RAM , so you need to check first whether your Mac model has a removable RAM or not. In some models, particularly MacBook Air and MacBook Pro, the RAM is soldered to the board and cannot be replaced.

Free Memory Mac Terminal

Before you think about installing more RAM, you should first try the tips listed below to free up your Mac memory.

How to Free Up RAM on macOS Mojave

There are several things you can do to manage your Mac memory usage and fix any RAM-related problems you are experiencing.

Reboot Your Mac

The first thing you should do when you free up RAM is to restart your Mac. Refreshing the system solves the problem most of the time, especially if the issue was caused by a minor glitch or an app that crashed. Restarting your Mac will delete the data on your RAM and any disk cache, so things should run smoother and faster after rebooting.

However, if you’re in the middle of something and you’re afraid of losing whatever you’re working on, restarting your computer might not be a good idea. If your macOS has hung because you ran out of memory but you don’t want to lose any unsaved information, you might want to try the other solutions below.

Update Your macOS

It is also possible that your memory problem is being caused by a macOS bug or issue. If this is the case, it is important to check whether you are running the latest version of macOS and install any necessary updates.

To check whether there’s an update you need to install, follow the steps below:

  1. Click the Apple logo and choose App Store under System Preferences.
  2. Click the Updates tab.
  3. Install all updates, if there are any.

After installing all the updates, restart your Mac and check whether your RAM problem has been resolved.

Check Memory Usage via Activity Monitor

When your app freezes or your Mac seems to be slower than usual, the first thing you need to check is the Activity Monitor. This is a built-in tool that shows you how much memory is being used, which apps are using it, and how much memory each app or process is hogging. The Activity Monitor will also help you determine if a particular process or app is consuming memory resources more than it should.

When you access the Activity Monitor app, you’ll see complete information regarding each running process or app. You can also add extra data by adding columns on the window.

To launch Activity Monitor, go to Finder > Go > Utilities > Activity Monitor or type in activity monitor in Spotlight. In the Activity Monitor Window, you’ll see a list of processes along with tabs of information regarding those processes, namely CPU, Memory, Energy, Disk, and Network.

Click on the Memory tab to understand how your memory is actually being used by your apps and processes. At the bottom of the window, you’ll see a graph on Memory Pressure and information regarding Physical Memory, Memory Used, Cached Files , and Swap Used. On the rightmost side of the graph, you’ll see data for App Memory, Wired Memory, and Compressed.

The Memory Pressure graph shows how much pressure your computer’s RAM is currently under. Ideally, the graph should be green, which indicates low pressure for your memory. A yellow graph means that you are short of memory while a red graph indicates a critical situation for your RAM, at which point you need to free up some space as soon as possible.

Free Memory For Mac Os

Follow the instructions below to free up some of your RAM using Activity Monitor:

  1. Launch Activity Monitor and click on the Memory tab.
  2. Click on the Memory column to arrange the processes according to their memory usage. Make sure that the processes are sorted out from the highest to the lowest.
  3. If you think that an app is consuming more than its share of memory resources, you can easily kill the process by clicking on the Quit button. Take note, however, that this does not necessarily kill the app. If the process you killed is a webpage, it will just close and reload that page without closing the browser. But if you closed a specific app, you’ll usually see a “closed unexpectedly” warning.

Warning: Don’t close processes that you are not familiar with because they may be related to other important processes on your computer.

Close Unnecessary Apps

Some Mac users are guilty of clicking the close button and thinking that the app is already close d. Note, though, that clicking the close button only closes the window, not the app itself. More often than not, you’re left with several apps still open without you even knowing about it.

Even without looking at the Activity Monitor, you can see which apps are running just by looking at the Dock. If you see a dot below the icon of the app, it means that these apps are still open.

Here’s how to properly close an application and free up some of your memory:

  1. Right-click the app icon on the Dock.
  2. Select Quit from the right-click menu.
  3. Alternatively, you can also choose Quit from the app’s top menu.

Tidy Up Your Files

If you have the habit of saving everything on your Desktop and just leaving them there, then you might want to organize your stuff to lessen the stress on your computer. macOS treats every icon on the Desktop as an active window, so the more items you have on it, the bigger your memory consumption will be.

Delete all unnecessary files and get rid of your junk files using an app such as Tweakbit MacRepair. You can also drag all of them into one folder to make your Desktop neat and tidy.

Delete Cache Files

Deleting cache files will help free up some of your memory, but this is not something a beginner should do. The Cache folder contains some system files that are important for your Mac to run properly, so you should know which files to delete and which ones to keep.

Free Memory Clean For Mac

If you’re confident that you know what you’re doing, you can delete cache files by following these steps:

Mac Free Memory Command

  1. Click Finder > Go > Go to Folder.
  2. Type in ~/Library/Caches/ in the dialog box.
  3. Delete the cache files that you don’t need in the folder, but make sure that you know what files you are deleting.

Clear Inactive Memory via Terminal

Free Memory For Mac

Another way to free up your computer’s memory is by purging it using the Terminal. To do this, open the Terminal and type in sudo purge. Hit Enter and type in the admin password. Next, wait as your Mac’s inactive memory is being deleted.

  1. Edit Your Finder Settings.

If you launch the Finder app and you see either All My Files or Recents, then you might want to change how your Finder app is configured because all the locations of the files shown in that window will be stored in RAM, therefore using up more resources. What you can do is show a specific folder so that only one location will appear.

To do this:

  1. Launch Finder and go to Preferences.
  2. Click the General tab.
  3. Under New Finder windows show , choose a specific folder such as Documents or Desktop.
  4. Close Finder and relaunch the app.

Free Memory Test Mac

If you have multiple Finder windows open, you can either close those that you don’t need or merge them all together. To merge all open window, click Window from the top menu and click Merge All Windows. This may not save you a huge chunk of memory space, but it helps.

Summary

Free Up Ram Mac

A computer’s memory is a precious commodity that needs to be managed strategically. Since upgrading RAM on Mac computers can be difficult, and sometimes not possible, you can try the methods above to gain back some breathing room for your memory. The trick here is to quit all that you don’t need, delete your junk files, and streamline your processes. Once you do, you’ll definitely notice a huge improvement in your Mac’s performance.
