11 Ways to Clear RAM and Reduce Memory Use on Mac

The Mac is a powerful machine, but like all computers, it can sometimes slow down due to excessive memory usage. This can result in sluggish performance and a less than optimal user experience. But don't worry, there are several ways to clear RAM and reduce memory use on your Mac. In this guide, we will explore 11 effective methods to help you keep your Mac running smoothly.

Quit Unnecessary Applications

One of the simplest ways to clear RAM on your Mac is by quitting unnecessary applications. Each open application uses a portion of your Mac's memory. By closing apps that you're not currently using, you can free up some of this memory and boost your Mac's performance.

To quit an application, simply right-click on its icon in the Dock and select 'Quit'. Alternatively, you can use the 'Command + Q' shortcut.

Use Activity Monitor: Activity Monitor is a built-in utility on your Mac that provides real-time information about the processes running on your computer. It can be a helpful tool in identifying applications or processes that are using a lot of memory.

To open Activity Monitor, go to 'Applications' > 'Utilities' > 'Activity Monitor'. Once it's open, click on the 'Memory' tab to see a list of all the processes and how much memory they're using. If you see an app that's using a lot of memory and you don't need it, you can quit it directly from Activity Monitor.

Restart Your Mac: Restarting your Mac can also help clear RAM. When you restart your computer, all the applications and processes that were running are closed, which can free up a significant amount of memory.

While it's not practical to restart your Mac frequently throughout the day, doing so every once in a while can be beneficial, especially if you notice that your computer is running slower than usual.

Use Terminal Commands: If you're comfortable using the Terminal, there are a few commands you can use to clear RAM on your Mac. One of these is 'sudo purge', which clears out inactive memory.

Keep in mind that using Terminal commands can be risky if you're not sure what you're doing, so proceed with caution and only use this method if you're confident in your abilities.

Manage Startup Items

Some applications are set to launch automatically when you start your Mac. While this can be convenient, it can also use up a lot of memory. By managing your startup items and preventing unnecessary apps from launching at startup, you can save memory and improve your Mac's performance.

To manage startup items, go to 'System Preferences' > 'Users & Groups' > 'Login Items'. From there, you can see a list of the apps that open at startup and remove any that you don't need.

Update Your Software: Keeping your software up to date is another way to reduce memory use on your Mac. Software updates often include performance improvements and bug fixes that can help your Mac run more efficiently.

To check for software updates, go to 'Apple menu' > 'About This Mac' > 'Software Update'. If any updates are available, you should install them.

Use a Memory Cleaner App: There are several third-party apps available that can help you clear RAM and reduce memory use on your Mac. These apps can provide a more user-friendly way to manage your memory compared to some of the other methods mentioned.

However, be careful when choosing a memory cleaner app. Some apps may not be reliable or could even harm your computer. Always choose an app from a trusted source and read reviews before downloading.

Reduce Visual Effects: MacOS uses a variety of visual effects for things like opening and closing windows. While these effects can make the user experience more enjoyable, they can also use up memory.

By reducing these visual effects, you can save memory and potentially improve your Mac's performance. To do this, go to 'System Preferences' > 'Accessibility' > 'Display' and check the box for 'Reduce motion'.

Use Safari's Reading List

If you tend to keep a lot of tabs open in your web browser, this can use up a significant amount of memory. One way to reduce this is by using Safari's Reading List feature.

With Reading List, you can save web pages to read later, allowing you to close tabs without losing the information. To add a page to your Reading List, simply click on the 'Share' button in Safari and select 'Add to Reading List'.

Upgrade Your RAM: If you're consistently running out of memory on your Mac, it might be worth considering a RAM upgrade. More RAM allows your computer to run more applications simultaneously without slowing down.

Keep in mind that not all Macs allow for RAM upgrades. If you're considering this option, make sure to check whether your Mac model supports it and consult with a professional if necessary.

Reset SMC and PRAM: Resetting the System Management Controller (SMC) and Parameter RAM (PRAM) on your Mac can also help clear RAM and reduce memory use. These resets can resolve a variety of issues, including slow performance.

Resetting the SMC and PRAM is a more advanced method and should only be done if you're comfortable with it. If you're not sure how to do it, it might be best to consult with a professional.
