How to Free up Memory on Mac: Three Most Effective Ways

by MacHelpAdmin

One of the most common questions among Mac users today is how to reclaim enough memory to provide great working performance. People are concerned about keeping their Mac in a good condition, so they look for any useful methods for speeding it up. The first solution that comes to mind is to do an effective Mac cleaning to remove unnecessary files and prevent system glitches.

But sometimes users don’t know how to clean Mac to free memory or have no time to clean their PCs manually. We understand that this is a boring or difficult process, but it is highly recommended to start with reclaiming RAM memory. This will definitely be useful for boosting the performance of your computer.

Try These Three Ways to Free Inactive Memory on Mac OS X

First, let’s clarify what inactive memory is on Mac. Inactive memory is used by recently active and terminated applications. The system of your computer saves this memory in case you want to use these applications again. If you no longer want to open those programs, the inactive memory will eventually be released or transferred.

But what to do when there is not enough memory and you see your Mac’s performance degradation? In this situation, we advise you to clear the inactive RAM by following the instructions below.

Before we begin, let us introduce one very useful and interesting application for Mac, namely MacFly Pro. This innovative cleaning software has been developed to take care of your Mac and keep it in a nice shape. MacFly Pro does the following: it removes inactive or old apps, as well as related files, cleans inactive memory, clears the cache and duplicates, gets rid of language and log files, and scans the overall condition to warn system of violations or threats. So if you want a fast and proper cleaning for your Mac, make sure you download and run MacFly Pro on your PC.

And now, we go directly to the ways how to free up ram on Mac:

1. Use Terminal

Open the Terminal application on your Mac.

Then, enter the command below:

sudo purge

After that, enter the password to clear inactive memory.

The advantage of this simple method is that it’s a default application and you don’t need to download any other programs. On the other hand, it might cause some slowdowns and so that you will have to enter the lines one more time.

2. Use Script Editor

The second way how to free up ram mac is to use Script Editor (the most popular technique used by Apple developers). Now, follow these steps:

Launch Script Editor

This is how it looks in an opened window:

Next, write down the following text:

display dialog “Free inactive RAM?” buttons {“Cancel”, “OK”} with icon 2 with title “Freeing RAM” default button 2

set buttonAnswer to the button returned of the result

if buttonAnswer is “ОК” then

say “Freeing RAM. Wait please.”

tell application “Terminal”

do shell script “purge”


end tell

say “Done!”

end if

After that, you should press ⌘+S and save the script in Application folders. Also, select Application format instead of Script.

This specific app is certainly useful, but actually, it is hard to open an app if you urgently need to clean your RAM on a Mac.

3. Use Third-Party Software

The last thing you do to free RAM is to look for and find some efficient cleaning applications. For instance, MacFly Pro is a great digital software and document scanner that will take care of your PC. With this app, you will forget about the necessity to clean Mac manually since it will do it for you in a matter of minutes. What is more, it will constantly support the system and optimize the performance of your Mac OS X.
