You can check your MacBook’s storage size in about ten seconds through About This Mac or System Settings, depending on your version of macOS. The exact storage size is one of the key details needed to get an accurate trade-in quote, so it is worth knowing before you request one from Mac Recycle.

Why Storage Size Matters When Selling a Mac

Storage is one of the main factors that determines what a Mac is worth at trade-in, alongside the model, year, processor type, RAM and condition. A MacBook Air with 512GB of storage will typically be worth more than the same model and year with 256GB. The difference in value is not always dramatic, but it can be meaningful, so it pays to know your exact figure rather than estimating.

Storage size also helps confirm which specific configuration you have. Two MacBook Pros from the same year can look identical on the outside but carry very different values depending on the storage fitted from the factory. Knowing this detail in advance means your quote will be accurate rather than subject to adjustment when the device arrives.

How to Check Your MacBook Storage on macOS Ventura or Later

If your Mac is running macOS Ventura, Sonoma, Sequoia or a newer version, follow these steps:

Click the Apple logo in the top left corner of your screen. Select System Settings from the dropdown. In the left-hand sidebar, click General, then choose Storage from the options on the right. The total storage capacity is shown at the top of the screen, along with a breakdown of how the space is being used.

How to Check Your MacBook Storage on macOS Monterey or Earlier

If your Mac is running macOS Monterey, Big Sur, Catalina or an older version, the steps are slightly different:

Click the Apple logo in the top left corner. Select About This Mac. In the window that opens, click the Storage tab at the top. Your total storage size will be shown here, along with a colour-coded bar that shows how the space is divided up.

If you are not sure which version of macOS you have, clicking About This Mac will show you the operating system name and version as the first piece of information on the overview screen.

The Figure You Need: Total Capacity, Not Free Space

The number to note is the total storage capacity, not the amount of free space currently available. For example, your Mac might show something like “356GB available of 512GB”. In that case, the storage size is 512GB. That is the figure to use when getting a quote.

Common storage sizes you might see include 128GB, 256GB, 512GB, 1TB, 2TB and 4TB. If the figure shown is slightly different, such as 499GB or 500GB, this will normally mean it is a 512GB drive displayed in a rounded format. If you are unsure which size yours corresponds to, Mac Recycle’s guide to finding your spec can help you confirm the exact configuration.

Does Storage Affect How Much My Mac Is Worth?

Yes. Along with the model, year, processor type, RAM and condition, storage is one of the specification points Mac Recycle uses to calculate a trade-in quote. Higher storage generally means a higher offer, though the exact difference varies depending on the model.

Understanding how Macs are graded can also help you understand what to expect when it comes to condition, which is assessed separately from specification. Together, the spec and condition determine the final offer.

Does It Matter Whether the Storage Is an SSD?

For the vast majority of MacBooks sold in the last decade, the answer is SSD. Apple moved its MacBook range to solid-state storage earlier than most manufacturers, and by 2015 virtually all MacBook models were shipping with SSDs as standard.

Some older iMacs and Mac minis from the 2013 to 2019 period may have a conventional hard drive or a Fusion Drive, which combines a small SSD with a larger spinning disk. For most laptops, this is not something you need to worry about, but if you are selling an older desktop Mac it is worth checking through the System Information screen. If the storage is listed as “Fusion Drive” or “HDD”, that is useful information to include when describing the device.

Does How Full My Storage Is Affect the Price?

No. The amount of free space on your drive at the time of trade-in has no effect on the value. Mac Recycle performs a certified data erasure on every device it receives, so the contents of the drive are wiped regardless. You do not need to delete files, clear your desktop or free up space before sending your Mac in.

That said, you should back up any files, photos or documents you want to keep before the trade-in goes ahead, as data cannot be recovered once the drive has been wiped. If you would prefer to run an erase yourself beforehand, you can do so, but it is not a requirement.

Frequently Asked Questions

Where do I find my MacBook’s storage size?

Go to the Apple menu in the top left corner of your screen. On macOS Ventura or later, go to System Settings, then General, then Storage. On earlier versions, go to About This Mac and click the Storage tab. The total storage capacity is shown at the top of the storage view.

What is the difference between storage size and available space?

Storage size is the total capacity your Mac was built with, for example 512GB. Available space is how much of that is currently free to use. When filling in a trade-in quote, you need the total capacity rather than the free space figure.

Does how full my Mac is affect its trade-in value?

No. Mac Recycle erases every device it receives, so the contents and available space on your drive do not affect the price offered. Back up anything you want to keep before sending it in.

Do I need to know my storage size before getting a quote?

Yes. Storage size is one of the key fields in the quote tool. Checking it beforehand through About This Mac or System Settings only takes a few seconds and means the quote you receive will be accurate.

Does more storage always mean a higher trade-in value?

Generally yes, within the same model and year. A 1TB MacBook Air will typically be worth more than a 256GB model of the same generation, though the gap varies. The model, year and condition all play a role alongside storage.

Can Mac Recycle identify my storage size from the serial number?

In some cases, yes. If you contact the Mac Recycle team with your serial number, they may be able to confirm the original storage specification. That said, checking through System Settings or About This Mac is quicker if the device is still in working order.
