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.
'Great for my mac.a BIG speed jump. Excellent upgrade for my 2010 mac mini.Highly recommended for any laptop needing a boost in memory as. This memory is definitely a great upgrade and I no longer have to worry about my memory but now I'm faced with my i5 chip slowing my computer down' 'Highly recommend for iMac 2017 27 inch model. This will purge your Mac’s inactive memory - something you might want to do after closing a particularly intensive app or game. Some features are available via the free app but there is an in.
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”
quit
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.

Removing or installing memory
Warning: The internal components of your MacBook Pro can be warm. If you have been using your MacBook Pro, wait ten minutes after shutting down the computer to let the internal components cool before continuing.
Step 1: Remove the bottom case
- Shut down your MacBook Pro. Disconnect the power adapter, Ethernet cable, USB cables, security lock, and any other cables connected to the MacBook Pro to prevent damaging the computer.
- Turn over your MacBook Pro and remove the ten (10) screws that secure the bottom case. Because the screws are different lengths, note the screw lengths and locations so you can replace the screws correctly. Put them aside in a safe place. Lift off the case and place it to the side.
- Touch a metal surface inside the computer to discharge any static electricity from your body.
Step 2: Remove existing memory (if present)
- Push the levers on the sides of the memory module in an outward direction to release the module from the memory card slot. The memory pops up at an angle. Before removing it, make sure you find the half-circle notches. If you don’t, try pressing the levers outward again.
- Hold the memory module by its notches and remove it from the slot.
- Remove the other memory module.
Important: Hold the memory modules by their edges, and do not touch the gold connectors.
Step 3: Install memory
- Align the notch on the gold edge of the module with the notch in the lower memory slot.
- Tilt the card and push the memory into the slot.
- Use two fingers with firm, even pressure to push down on the memory module. There should be a click when you insert the memory correctly.
- Repeat this procedure to install an additional memory module in the top slot. Press down on the module to make sure it is level.
Note: Make sure you install the memory according to this illustration, with the gold contacts inserted almost completely into the connector.
Step 4: Replace the bottom case
Replace the bottom case. Replace and tighten the ten screws you removed earlier, making sure to put the different length screws in their proper locations.

Removing or installing memory
You will need to remove the battery before installing additional memory and reinstall the battery after installing the memory. The following procedure includes all the necessary instructions for both parts of the process.
Warning: The internal components of your MacBook Pro can be warm. If you have been using your MacBook Pro, wait ten minutes after shutting down the computer to let the internal components cool before continuing.
Step 1: Remove the battery

- Turn the computer over.
- Locate the battery release latches on each side of the battery.
- Slide both latches up. The battery should pop up slightly.
- Lift the battery out.
Step 2: Remove the memory door
- Using a Phillips size 00 screwdriver, unscrew the memory door and remove it from the battery bay of your computer. Depending on the model of your MacBook Pro, you may have three or four screws.
- Touch a metal surface inside the computer to discharge any static electricity from your body.
Step 3: Remove existing memory (if present)
If you need to remove a memory card—for example if you are replacing it or if you need to get past the memory in the top slot to access the bottom slot—you can remove the card by spreading the tabs on each side of the card away from the notches in the memory card. The card should pop up slightly. Lift the memory card to about a 25-degree angle and then gently slide the card out of the memory slot.
Important: Hold the memory modules by their edges; do not touch the gold connectors.
Step 4: Install memory
- Insert the new memory card at a 25-degree angle. Line up the notch in the card with the small tab in the memory slot and slide the card into the slot until the gold edge is almost invisible. Firmly press the memory card into the memory slot. You might feel some resistance.
- Gently spread the small tabs in the memory slot away from the notches and push the memory card down until the two tabs on either side of the card lock into place.
- Insert any additional memory into the second slot.
Note: Make sure you install the memory according to the illustration below, with the gold contacts inserted almost completely into the connector.
