Who else wants MacBook Air RAM upgrade? First, you need to know what the RAM is. 

Random Access Memory or RAM is a temporary storage solution used by your Mac's CPU. It's a short-term storage space where specific process and task data is held. Your CPU can access the RAM data much faster than the hard-drive information, making it a critical element that helps your Mac operate smoothly. 

RAM upgrades give a substantial boost to Mac performance. No wonder so many Mac owners desire to upgrade. But here’s what they wish they'd know before buying MacBook Air.  

Can you upgrade RAM on Macbook Air? 

The sad news is that a MacBook Air RAM upgrade is not possible. Ram on this particular model soldered on logic board, making it impossible to upgrade. But don’t lose hope! Even though not all Mac models allow new RAM, there are plenty of options to free up current RAM and improve its overall performance. That’s what I’m here for, to help you do it. 

Let's have a closer look at what you can do to optimize MacBook Air.

But often, we forget that keeping Mac up-to-date fixes so many bugs, improves performance, protects from threats, and ensures you always have the latest features and updates available. RAM optimization also comes in this package of an impressive ray of benefits. Read how to update Mac below.

Cache clogs up your RAM over time, so clearing it regularly helps optimize it. Here's how:

Cache folders

  1. Open Finder and press Shift-Command-G

  2. In the text box, enter /Library/Caches and press return.

  3. Select all files and folders by pressing Command-A.

  4. Press Command-D to delete them all.

4 Ways to speed up a Macbook Air 

1. Check for battery-draining apps.

Such apps will cause any Mac to slow down. Activity monitor is a helpful tool for surveying battery-draining apps. Open it via a spotlight search by pressing Command-Space and typing Activity Monitor.

Once open, you will see it monitors six different resources, which are listed in the top row. Let's take a look at those responsible for increasing speed and RAM.

If your Mac is slow, take a look under the CPU tab. It tracks all the tasks and processes running on your Mac in real-time. The heavy consumers will be listed at the top. Feel free to close any application by selecting it and pressing "X" in the left-hand corner.


This tab indicates how much memory each app, task, or process is currently using. Take a look at the bottom graph to understand efficient memory management better. If it's yellow or red, this is a good indication that your Mac is low on RAM. Again, resource-heavy apps will be at the top of the list. Close the ones you don’t need.


Look, your biggest battery drainers will be listed here. So be sure to close anything you don't need right now. 

2. Manage startup items

When your Mac is launched, multiple launch items like Safari, Adobe, Chrome, and Teams will also be trying to launch simultaneously. That can slow down your Mac. Try this one straightforward fix to remove any unnecessary launch items, giving your Mac space to breathe.

  1. Select the main Apple Menu > System Preferences > Users & Groups > Login Items.

  2. Select the lock icon bottom left to make any changes.

  3. Select any unneeded launch items from the list and press the "-" to remove them.

That should speed up your Mac next time you reboot! 

3. Disable visual effects

Turning off visual effects is another simple way to speed up your MacBook Air. Read the instructions below.

How to disable visual effects

  1. Select the main Apple Menu > System Preferences > Dock & Menu Bar.

  2. On the dropdown for Minimize windows using, ensure Scale effect is selected, then untick the following:

  • Animate opening applications.

  • Automatically hide, and show the Dock.
