What is Apple silicon? Check which Mac you have

What Apple silicon means

Apple began moving Macs from Intel processors to its own chips in late 2020. “Apple silicon” identifies that hardware family; it isn't the name of a macOS release or an app you install. An operating-system update cannot turn an Intel Mac into an Apple silicon Mac.

Apple's current identification page includes MacBook Neo, the M1 and later Air and Pro families, recent iMac and Mac mini models, Mac Studio and the 2023 Mac Pro. The chip label on your own computer is a better first check than guessing from the case, purchase year or the words “MacBook Pro”.

In particular, some Intel and M1 MacBooks were both introduced in 2020. Buying a Mac in 2021 doesn't prove it was a model introduced in 2021. A secondhand listing that says only “2020 Mac” leaves a meaningful question unanswered.

Check Apple silicon or Intel in About This Mac

On macOS 15 Sequoia, macOS 26 Tahoe and macOS 27 Golden Gate, choose Apple menu › About This Mac. Read the line beneath the model information:

What it says	What it means
Chip: Apple M1, M2, M3, M4, M5 or another Apple chip	The Mac uses Apple silicon.
Chip: Apple A18 Pro	The MacBook Neo is also Apple silicon.
Processor: Intel…	The Mac is Intel-based.

The list of M names above is illustrative, not a limit on which future or newer M-series label counts. Apple uses Chip for Apple silicon and Processor followed by Intel's name for Intel-based models.

You don't need to publish your serial number to answer this. If you're asking a developer which download to use, the chip name and macOS version are normally the relevant details. For a buying decision, request the exact model and configuration as well, since chip family alone doesn't establish memory, storage or port capabilities.

If you prefer Terminal, sysctl -n machdep.cpu.brand_string is a read-only check of the processor brand string. We ran this exact command on the Mac used for this documentation check; it returned Apple M2 Max. It changes nothing and requires no password. About This Mac remains the simpler built-in route.

Why the architecture matters

With M1, Apple described bringing CPU, graphics, input/output, security and other technologies together in a system on a chip. Its architecture explanation also describes a shared pool of memory accessible to different parts of the chip, rather than copying the same data between separate memory pools.

That helps explain the term unified memory in specifications. It is still working memory with a finite capacity, separate from SSD storage. The architecture isn't a rule that a smaller amount always equals a larger amount on another computer. Look at the actual workload and Memory Pressure when deciding how much you need.

Different Apple silicon chips also have different capabilities. A base chip, a Pro, a Max and an Ultra are not interchangeable configurations. Neither the Apple silicon label nor a newer generation on its own tells you which machine will complete a particular job faster. Use the app's requirements and the exact model specifications.

Battery runtime and heat depend on the whole computer and task, too. A laptop's battery size, display, cooling design, software and workload matter alongside the chip. The Neo and Air comparison is a concrete example: both are Apple silicon and fanless, yet their memory choices and battery ratings differ.

Choose the right app download

A developer may label downloads Apple silicon, Intel or Universal. Prefer the native Apple silicon or Universal version for an Apple silicon Mac. Universal means the app contains support for both processor families; the download name alone doesn't tell you whether every plug-in or driver is compatible.

Rosetta translates supported Intel apps for Apple silicon. It doesn't change the chip in your Mac and isn't a reason to download an Intel build when the developer supplies a native one. Apple's current guidance says general Rosetta support is available through macOS 27; from macOS 28 its functionality will be limited to certain older unmaintained games using Intel frameworks.

Before upgrading a Mac that relies on an Intel-only app, check the developer's plan for that app and all required add-ons. A Universal main app can still depend on an Intel-only plug-in. Don't assume that an app opening today guarantees it will work on the next major macOS.

Use Activity Monitor for a running app's processor kind when troubleshooting compatibility. An Intel app running through translation doesn't make the Mac itself Intel-based. The hardware answer remains the Chip line in About This Mac.

Startup and troubleshooting instructions differ

The processor family matters when following repair instructions. Apple silicon uses a held power button to enter startup options and macOS Recovery. Intel recovery shortcuts begin with keyboard combinations such as Command-R. Applying the wrong family of instructions can make a working shortcut appear broken.

Apple's SMC instructions also distinguish the families: on Apple silicon, connect power and restart or shut down and start again; the reset is automatic. Intel laptops have model-dependent key sequences. The fact that a guide says “MacBook” is not enough to choose the sequence.

For normal performance troubleshooting, you can still use built-in Activity Monitor on either family. The slow-Mac guide starts with the symptom instead of treating processor branding as the diagnosis.

Check macOS and app requirements separately

Apple's macOS 27 compatibility list supports Apple silicon Macs. An Intel Mac cannot install that release through the supported update path. That doesn't turn every older operating-system build or every app into an immediate failure; check the supported versions for the software you use.

An app can require both a processor family and a minimum macOS version. Meeting one condition doesn't meet the other. Open Apple menu › About This Mac for both facts, and compare them with the developer's requirements before downloading.

This also prevents a common purchase mistake: buying a Mac because the chip is supported without checking whether its memory and disk meet your workflow. Treat processor compatibility, memory capacity, storage capacity and software requirements as related but separate checks.

Where Tend fits

Tend requires Apple silicon and macOS 15 or later. Its free CPU, memory, estimated per-app watts and battery-health readings help explain the Mac you have; it doesn't run on Intel or convert Intel apps. Pro adds longer energy history, more sensors and actions described on the Free and Pro comparison.

Questions

How do I know whether my Mac is Apple silicon or Intel?

Choose Apple menu › About This Mac. Apple silicon models show Chip and an Apple chip name; Intel models show Processor and an Intel processor name.

Is the MacBook Neo Apple silicon?

Yes. Apple lists MacBook Neo among Apple silicon Macs; its A18 Pro chip qualifies even though the name does not begin with M.

Can I install Apple silicon on an Intel Mac?

No. Apple silicon is hardware, not software. Installing a newer macOS or Rosetta does not change the processor in an Intel Mac.

Does Apple silicon mean an app will run?

Not by itself. Check the app’s minimum macOS version, processor support and required plug-ins or drivers. Prefer an Apple silicon or Universal build when available.
