Your Mac’s SSD (solid state drive) is one of the most important components of your computer. Unlike a traditional hard drive, an SSD has no moving parts, which makes it much more resistant to physical damage. However, SSDs can still fail if they become corrupted or if they start to wear out.

Fortunately, there are a few ways to check the health of your SSD and make sure it is still working properly. In this article, we will show you how to use the built-in Apple Diagnostics tool to check your SSD health, as well as how to use third-party tools like DriveDx.

How to Check SSD Health on Mac?

It’s important to keep tabs on the health of your solid state drive (SSD), and macOS makes it easy to do so. This guide will show you how to check SSD health on your Mac, what the different ad statuses mean, and how you can fix common SSD problems.

When an SSD is first installed, it is given a clean bill of health. However, as time goes on and the drive is used more frequently, its health will start to decline. This is natural and to be expected, but there are some things you can do to help prolong the life of your SSD.

One way to keep an eye on your SSD health is to use Apple’s built-in Disk Utility application. Disk Utility can be found in the Applications > Utilities folder, or by searching for it in Spotlight.

Once open, select your SSD from the list of drives on the left-hand side. Then, click the “First Aid” button at the top of the window. disk utility will now scan your SSD for any issues that need to be addressed.

If no errors are found, you will see a message that says “Your disk appears to be OK.” However, if Disk Utility does find any problems with your SSD, it will attempt to repair them automatically.

In some cases, Disk Utility may not be able to fix the problem and you will see a message that says “Disk Utility can’t repair this disk.” In this case, you may need to take additional measures, such as repartitioning or reformatting your drive, in order to fix the issue.

It’s also a good idea to periodically check for firmware updates for your particular model of SSD. Firmware updates can help improve performance and stability, as well as address any known issues with the drive.

2.1 Using Apple Diagnostics

Apple Diagnostics is a hardware diagnostic tool designed by Apple. It tests for hardware issues and provides feedback on any problems that it finds. If your Mac was manufactured after June 2013, you can use Apple Diagnostics to test your Mac’s memory, storage, sensors, and other hardware components.

To use Apple Diagnostics, restart your Mac and hold down the D key while it starts up. After a short delay, Apple Diagnostics will begin testing your Mac’s hardware. The test takes a few minutes to complete and will provide you with a report on any issues that it finds.

If you’re having trouble running Apple Diagnostics or if it doesn’t find any issues with your Mac’s hardware, you can try running the tests again in safe mode. To do this, restart your Mac and hold down the Shift key while it starts up. After a short delay, you should see the Apple logo appear onscreen. When the login window appears, you can release the Shift key and log in as usual. Once you’ve logged in, open System Preferences and click on the “Startup Disk” pane. Select your startup disk from the list of options and click on the “Restart” button. Your Mac will now restart in safe mode and you can run Apple Diagnostics again.

2.2 Using Apple Hardware Test

If you have an SSD installed in your Mac, it’s important to keep an eye on its health. There are a few ways to do this, but we’re going to focus on two methods: using Apple Hardware Test and using the System Information app.

Apple Hardware Test is a built-in tool that can diagnose both hardware and software issues on your Mac. To use it, you’ll need to restart your Mac and hold down the D key while it boots. This will take you to the Apple Hardware Test utility.

Once in the utility, you can choose whether to test your Mac’s memory, disk drives, or sensors. For our purposes, we’re interested in the “Disk Drive” test. Select that option and then click on the “Test” button.

The utility will now scan your SSD for any issues. If it finds any, it will give you a description of the problem and ask if you want to attempt to repair it. We recommend letting the utility attempt to repair the issue if possible.

If you don’t want to use Apple Hardware Test or if you’re having trouble getting it to work, you can also check your SSD health from within the System Information app. To do this, open the app (you can find it in the Utilities folder), and then select “Storage” from the list on the left side of the window.

You should now see a list of all storage devices connected to your Mac, including your SSD. Select it from the list and then look at the “SMART Status” field towards the bottom of the window. If this field says “Verified,” then your SSD is healthy; if it says anything else, then there may be some issues with your drive that you’ll want to investigate further


That’s all you need to do to check the health of your Mac’s SSD. Keep in mind that these tips are meant for advanced users, and if you’re not comfortable with the Terminal, it’s best to leave things as they are.
