Where to find your Mac model number in System Settings

Your Mac model number is a short code — usually starting with "Mac" followed by numbers or a product name — that identifies exactly which Mac you own. You can find it in one place on every Mac: the System Settings app. Click the Apple menu in the top-left corner, select "System Settings" (or "System Preferences" on older Macs), then look for "About" in the left sidebar. Your model identifier appears on the main panel under "Model Identifier" or "Model Name".

The model number is different from your serial number, which is longer and unique to your individual machine. You need the model number when you're looking up technical specifications, checking compatibility with software or hardware, or troubleshooting problems specific to your Mac type.

Key Takeaways

  • Your Mac model number appears in System Settings under the About section, listed as "Model Identifier" or "Model Name".
  • The model number looks like "MacBookPro18,1" or "iMac21,2" and tells you the type and generation of your Mac.
  • You can also find the model number printed on the bottom of your Mac or inside the battery compartment on some older models.
  • The model number is different from your serial number, which is unique to your individual machine and also appears in the About section.

Finding the model number on the physical Mac itself

If your Mac won't start up or you need the information without turning it on, look at the bottom of the device. Most Macs have a label printed on the underside that lists the model number along with the serial number, regulatory information, and power specifications. On MacBooks, this label is usually near the hinge or along the bottom edge.

Older Mac models sometimes printed the model number inside the battery compartment. If you have a Mac from 2015 or earlier, you may need to remove the battery to see this label. For iMacs and Mac minis, the label is typically on the bottom or back of the unit.

What the model number tells you about your Mac

The model identifier code breaks down into two parts: the product line and the generation number. For example, "MacBookPro18,1" means it's a MacBook Pro from the 18th generation. This matters because different generations have different processors, memory limits, and compatible software versions.

When you search your model number online, you'll find the exact specifications for your machine — how much RAM it can hold, what processor it has, which macOS versions it can run, and whether it supports specific external devices. This is especially useful when you're buying upgrades or deciding whether your Mac can run new software.

Using your model number to check macOS compatibility

Before you update your operating system, use your model number to confirm your Mac supports the new version. Apple's official specifications page lists which Mac models can run each macOS release. Search for your model identifier on Apple's site, and you'll see the maximum macOS version available for your machine.

Some older Macs cannot run the latest macOS, and trying to force an update can cause problems. Knowing your model number ahead of time prevents you from attempting an incompatible update.

Finding the model number if you're buying a used Mac

If you're considering a used Mac, ask the seller for the model number before you buy. This lets you research the age, condition expectations, and remaining useful life of the machine. You can also use the model number to check the original purchase date through Apple's support site — search for the serial number along with the model number.

The model number also helps you spot misrepresented listings. If a seller claims the Mac is newer than it actually is, the model number will show the truth. Cross-reference the model number with Apple's official product lineup to confirm the year and specifications.

Model numbers for different Mac types

Mac model numbers follow a consistent pattern across product lines. MacBook Air models use "MacBookAir" followed by generation numbers. MacBook Pro uses "MacBookPro" with generation numbers. iMac uses "iMac" with generation numbers. Mac mini uses "Macmini" with generation numbers. Mac Studio uses "MacStudio" with generation numbers.

The generation number increases with each new release, though Apple doesn't always release new models every year. A higher generation number generally means a newer machine with more current technology, but the exact year depends on the product line and when that generation launched.

Frequently Asked Questions

Is the model number the same as the serial number?

No. The model number identifies the type and generation of your Mac — for example, "MacBookPro18,1". The serial number is a unique code specific to your individual machine. Both appear in the About section of System Settings, but they serve different purposes.

Can I find the model number if my Mac won't turn on?

Yes. Look at the bottom or back of your Mac for a printed label with the model number, serial number, and regulatory information. On MacBooks, this label is usually near the hinge or along the bottom edge. You don't need to power on the machine to read it.

What should I do if the label on my Mac is worn or unreadable?

If the physical label is damaged, your only option is to access System Settings on a working Mac. If the Mac won't start, you may need to take it to an Apple Store or authorized repair shop where they can look up the information in their system using the serial number.

Does the model number change if I upgrade my Mac's memory or storage?

No. The model number stays the same regardless of upgrades. It identifies the original hardware configuration and generation. Upgrades don't change what model your Mac is.
