Start with About This Mac
On macOS 15 Sequoia, 26 Tahoe and 27 Golden Gate, choose Apple menu › About This Mac. This is Apple's simplest identification route. Record the model name, screen size and chip or processor rather than relying on a case colour or purchase year.
Chip followed by an Apple name means Apple silicon; Processor followed by Intel identifies an Intel Mac. The Apple silicon guide explains that separate compatibility question, including the Neo's A18 Pro.
The same window shows the installed macOS name and version. Apple says clicking the version number reveals the build number when you need it for troubleshooting. Hardware generation and operating-system version are different facts: updating macOS doesn't change your Mac's model year.
Get the precise details in System Information
- Hold Option while opening the Apple menu.
- Choose System Information.
- Select Hardware in the sidebar.
- Record the Model Name, Model Identifier, chip or processor and memory relevant to your question.
These fields help distinguish similar-looking computers. For example, the documentation Mac used here reports Mac14,5, Apple M2 Max and 32 GB memory. Apple's Pro identification page maps that identifier to the relevant model family. It is an example, not a specification for every 14-inch MacBook Pro.
| Detail | What it identifies |
|---|---|
| Model name | The product family and, when shown, size and generation. |
| Model identifier, such as Mac14,5 | An Apple hardware model family used in its identification pages. |
| Chip and memory | Important configuration details within a family. |
| Part number | A configuration or regional product code listed by Apple. |
| Serial number | The particular device, used for Apple's support and coverage checks. |
A shared model identifier isn't a substitute for checking every configuration detail. Ask about memory, storage, chip tier and condition when evaluating a used Mac, even when two machines map to the same generation.
Find the introduction year
Use Apple's MacBook Air or MacBook Pro identification page and match the model identifier or part number. Apple's general model-name guide links identification pages for the other Mac families too.
Read Year introduced and follow the model's technical-specification link. The introduction year describes the model, not necessarily the year your particular unit was manufactured, purchased or first activated. A Mac bought in 2025 can be an earlier model sold later.
The words “2020 MacBook Pro” are particularly ambiguous because Apple introduced Intel and M1 models that year. Port count and processor details can matter to supported macOS versions. Use the exact record rather than assuming every computer sharing a calendar year is equivalent.
Check the current macOS compatibility page separately. An identification page's older “newest compatible” text can lag a newly published operating-system list; the update guide links Apple's release-specific checks.
Optional: read the hardware overview in Terminal
The graphical route is enough for most people. If you prefer Terminal, this built-in command reads the hardware overview without changing settings or needing an administrator password:
system_profiler SPHardwareDataTypeThe output includes unique device identifiers, including the serial number. Don't paste the entire output into a public forum, listing or chat. Share only the model and configuration fields needed; provide the serial directly to Apple for an appropriate support or coverage check.
We verified the command's hardware fields on this Mac on 23 October 2026, filtering the research output to model, chip and memory. The public example above omits unique identifiers. This was a read-only inspection, not a benchmark.
A saved System Information report can contain much more than a model name. Review and redact it before sending it to someone else; a short description is often enough to answer a download or compatibility question.
Find the serial and use Apple's lookup
Apple documents the serial in About This Mac and System Information › Hardware. You can enter it yourself on Apple's Check Coverage website to identify the model and check the information Apple makes available for that device.
Use Apple's website directly. A third-party serial-number decoder isn't necessary to identify the Mac and should not be treated as authoritative proof of manufacturing date, ownership or condition. A successful serial lookup also isn't a physical inspection of a used computer.
If sharing an About This Mac screenshot, cover the serial before publishing it. The model, chip, memory and macOS version normally answer an app developer's compatibility question without the full device identifier.
If the Mac won't start or isn't with you
Apple says the serial is usually printed on the Mac's underside near regulatory markings and on the original packaging. Packaging can also show a part number, which its identification pages can match to a model.
Apple also documents account.apple.com › Devices on a device where you can sign in to your own Apple Account. If the Mac is listed, its entry can show the model and serial. We did not sign in or submit a serial to research this guide.
Use the no-power checks for a computer that won't start. Identification helps choose the correct charger and repair procedure, but doesn't itself explain a startup fault.
What a buyer or seller should record
Keep the exact model, chip, memory, storage capacity and macOS version together. For a laptop, add battery condition and cycle count from the battery-health guide. Those readings add condition context, not a guarantee of future runtime.
For sale or transfer, follow Apple's erase and preparation workflow after backing up. Reading the serial or signing out of a website isn't the same as preparing the Mac for a new owner.
How Tend helps after identification
On Apple silicon with macOS 15 or later, Tend's free battery-health and cycle readings can complement the hardware details when evaluating the laptop you have. It doesn't validate ownership, turn a serial into a condition report or expand macOS compatibility.
Questions
How do I find out what MacBook I have?
Choose Apple menu › About This Mac. For a precise model identifier, hold Option while opening Apple menu › System Information and select Hardware, then match the identifier to Apple’s model page.
Is the purchase year the Mac's model year?
Not necessarily. A model can remain on sale after its introduction year. Use Apple’s Year introduced field for the matched model instead of the date you bought it.
Where can I look up a Mac serial number?
Enter it directly on Apple’s Check Coverage website. Avoid posting the serial publicly; a model and configuration usually provide enough information for compatibility questions.
Can I identify a Mac that will not turn on?
Apple documents the serial on the Mac’s exterior or original packaging, and in its entry under your Apple Account’s Devices list when available. Use those details with Apple’s lookup.
