RAM, or Random Access Memory, is key to how well your Mac works. It lets you use multiple apps at once without slowing down or crashing. But sometimes, your Mac doesn’t have enough RAM for all your apps. Adding more RAM to your Mac can really help it run better and faster. In this guide, I’ll show you how to upgrade your Mac RAM easily. Let’s get started!

Before We Begin

If you don’t have enough RAM, your Mac becomes slow and often crashes. To keep your RAM usage in check, download MacKeeper and use its Memory Cleaner. It frees up RAM and improves system performance.

2. Use Activity Monitor to Check RAM Usage

Activity Monitor is a built-in utility tool on macOS. It provides detailed information about your Mac’s performance, including CPU usage, network activity, and RAM usage. You can check if your Mac is running out of memory using Activity Monitor.

Here’s how to check RAM usage on Mac via Activity Monitor:

  1. Open Activity Monitor by going to Applications > Utilities > Activity Monitor.

Which Mac Models Allow RAM Upgrades?

When thinking about adding more memory to your Mac, keep in mind that not all Macs let you upgrade the RAM. For instance, most new MacBooks, like the MacBook Air, have built-in RAM that you can’t change or upgrade.

Here’s a list of all Mac models that allow RAM upgrades and the ones that don’t:

Mac ModelRAM Upgradeability
MacBook Pro 17″ (All Models)Yes
MacBook Pro 15″ ( 2008–2012 Models)Yes
MacBook Pro 13″ (2009–2012 Models)Yes

*Upgradeability in these models may be limited, and upgrading the RAM could be more difficult or require professional assistance.

Please note that starting in late 2020, Apple began releasing Mac models with the Apple Silicon M1 chip, which has integrated RAM and is not upgradeable. Always check the specific model and configuration of the Mac you are interested in to determine if the RAM can be upgraded.

How to Upgrade Your Mac RAM: 7 Steps

After identifying whether your Mac allows RAM upgrade or not, it’s time to upgrade your Mac RAM.

Upgrading your Mac RAM involves a lot of technical steps, and you need to be careful when performing this procedure. Any damage to the components or improper installation of the RAM modules can result in severe damage to your Mac.

Follow the procedure below to upgrade your Mac RAM successfully.

1. Identify your Mac Model

The first step in upgrading your Mac RAM is identifying your Mac model. It is important because not all Macs are compatible with RAM upgrades, and different models require different types and amounts of RAM.

To identify your Mac model, follow these steps:

  1. Click the Apple logo and select About This Mac.
click apple icon and select about this mac
  1. The new window will display your Mac’s model name, such as MacBook Pro or MacBook Air (Retina, 13-inch, Mid 2014).
about this mac info
  1. Note your Mac’s release year, displayed in the same window.
  2. Once you have identified your Mac model and year, check for RAM upgrade compatibility in the section above or on Apple’s official website.
  3. Some Macs have RAM soldered to the motherboard and cannot be upgraded, while others have slots for adding additional RAM. Checking for compatibility will ensure you save time and money on an impossible RAM upgrade on your Mac.

2. Choose the Right RAM

Once you know your Mac model and if it can be upgraded with more RAM, the next step is picking the right RAM. Remember, not all RAM is the same. Different Macs need different types of RAM with specific speeds.

To choose the right RAM for your Mac, you will need to know the following specifications:

  • RAM type (DDR, DDR2, DDR3, DDR4)
  • RAM speed (MHz)
  • The maximum amount of RAM supported by your Mac

You can find this information by consulting Apple’s documentation. You can also use a third-party tool like Crucial System Scanner, which will scan your Mac and recommend compatible RAM upgrades.

Once you have determined the correct RAM type, speed, and maximum amount, buy the RAM from a reputable vendor to ensure its quality and compatibility.

3. Gather the Necessary Tools

Before upgrading your Mac’s RAM, gather the necessary tools. Make sure you have all the necessary tools before beginning the RAM upgrade process so you do not have to stop mid-process to search for devices.

The tools you will need include:

  • 🛠️ Screwdrivers: A set of screwdrivers, including a Phillips head and a Torx driver, to open your Mac and remove the existing RAM. 
  • ⚡ A Grounding Strap: A grounding strap prevents electrostatic discharge, which can damage sensitive electronic components. Wear a grounding strap or touch a grounded metal surface before handling electronic components. 
  • 🧹 A Clean, Flat Surface: You will need a clean, flat surface to work on while upgrading your Mac’s RAM. 
  • 💾 The New RAM: You will need the new RAM that you have purchased to replace the existing RAM.

4. Backup Your Data

Before upgrading your RAM, back up your data on Mac to ensure you don’t lose important files or data during the process. If you have a backup, you can easily restore your data if anything goes wrong during the upgrade process.

Here’s how to use Time Machine to backup your data:

  1. Connect an external hard drive to your Mac.
  2. Open System Settings from the Apple menu.
click the apple icon and select system settings
  1. Click General and select Time Machine.
click general and select time machine
  1. Give access to Time Machine for backing up your data using your Mac password or Touch ID.
enter admin id and password
  1. Tap the Add Backup Disk button and choose the external hard drive you connected.
click the add add backup disk button in time machine
  1. Click Use Disk, and it will start backing up your data to the external drive.

5. Open Your Mac

Now that you have identified the type of RAM and the maximum amount of RAM your Mac can handle, it’s time to open up your Mac and install the new RAM.

🚨 Be aware that opening your Mac and performing any hardware modifications may void your warranty or AppleCare coverage. If your Mac is still under warranty, contact Apple Support for assistance with memory upgrades.

Here’s how you can open your Mac to upgrade its RAM:

  1. Shut down your Mac and unplug it from the power source. Also, unplug the Ethernet cable, USB cables, security lock, and other cables to avoid damaging the device.
  2. Turn your Mac over and locate the 10 screws on the bottom. Use a screwdriver to remove the screws.
