## In short

- Macs with Apple Silicon M3, M4, or newer chips feature dedicated AV1 hardware decoding in their Media Engine.
- M1 and M2 Macs have no AV1 hardware, but apps that include a software decoder such as dav1d play it smoothly on the CPU.
- Both decode paths produce identical picture quality, but hardware decoding consumes far less battery power.
- QuickTime Player plays AV1 only in MP4 or MOV files, on Macs that decode it in hardware; it never opens MKV or WebM.
- MacLC routes AV1 through VideoToolbox on M3+ and dav1d on M1/M2 automatically with zero configuration.

With the right app, every Apple Silicon Mac plays AV1. Macs with an M3 chip or newer decode it in hardware, in their media engine; M1 and M2 Macs have no AV1 hardware, so they need an app that brings its own software decoder, such as dav1d.

Both give exactly the same picture (AV1 decoding is defined to the pixel), but hardware decoding uses far less power. On an M3 or newer MacBook, AV1 plays cool and easy on the battery; on earlier chips, 4K AV1 keeps the CPU busy.

## What is AV1 and why is it replacing older codecs?

AOMedia Video 1 (AV1) is an open-source, royalty-free video compression standard designed specifically for internet video distribution. It comes from the [Alliance for Open Media](https://aomedia.org/), a consortium whose members include Google, Apple, Microsoft, Amazon, Netflix, Meta, Intel and Mozilla.

AV1 was engineered to resolve the two biggest limitations of High Efficiency Video Coding (HEVC / H.265): fractured patent licensing fees and bandwidth saturation. Because AV1 is royalty-free, streaming services and browsers adopted it widely.

In terms of compression efficiency, AV1 is a significant technical advance:

1. Published tests put it at roughly half the bitrate of H.264 (AVC) for similar quality.
2. And roughly 20 to 30 percent below HEVC and VP9.
3. That lets services send 4K over connections that used to carry 1080p.

The savings vary with the content and the encoder, but they are why services keep moving their catalogs to AV1. To explore the mathematical comparisons between these standards, read our detailed analysis of [H.264 vs H.265 vs AV1](/maclc/blog/h264-vs-h265-vs-av1/).

## Which Mac models feature AV1 hardware decoding?

Apple added AV1 hardware decoding with the M3 chips in late 2023. Every M3 or newer chip has it in its media engine.

The breakdown of Mac models and their AV1 playback capabilities is straightforward:

| Mac Model Family | Processor Architecture | AV1 Playback Method | Battery Efficiency |
| :--- | :--- | :--- | :--- |
| **MacBook Pro (Late 2023 & Newer)** | Apple M3, M3 Pro, M3 Max, M4, M4 Pro, M4 Max | Dedicated Hardware Decoder | High (minimal power draw) |
| **MacBook Air (2024 & Newer)** | Apple M3, M4 | Dedicated Hardware Decoder | High (minimal power draw) |
| **iMac (Late 2023 & Newer)** | Apple M3, M4 | Dedicated Hardware Decoder | High (AC Powered) |
| **Mac mini & Mac Studio (M4 / M4 Pro / M4 Max)** | Apple M4 family | Dedicated Hardware Decoder | High (AC Powered) |
| **MacBook Pro (2020–Early 2023)** | Apple M1, M1 Pro, M1 Max, M2, M2 Pro, M2 Max | Multi-threaded Software (dav1d) | Moderate (higher CPU draw) |
| **MacBook Air (2020–2023)** | Apple M1, M2 | Multi-threaded Software (dav1d) | Moderate (higher CPU draw) |
| **Mac Studio & Mac Pro (2022–2023)** | Apple M1 Ultra, M2 Ultra | Multi-threaded Software (dav1d) | Smooth (High CPU capacity) |
| **All Intel Macs (2020 & Older)** | Intel Core i5, i7, i9, Xeon | CPU Software Decoding | High CPU draw / Fan noise |

M1 and M2 chips have no AV1 circuits, but their CPU cores are fast enough for a good software decoder to play 1080p and usually 4K AV1 smoothly, at the cost of more power.

## How do you check which chip is inside your Mac?

If you are unsure whether your Mac possesses dedicated AV1 hardware silicon, you can check your processor model in macOS in just a few seconds.

Follow these steps:

1. Click the **Apple menu ()** in the upper-left corner of your desktop screen.
2. Select **About This Mac** from the dropdown menu.
3. In the overview window that appears, look for the **Chip** specification line.
4. Check the processor label:
   - If the label reads **Apple M3**, **Apple M3 Pro**, **Apple M3 Max**, **Apple M4**, or higher, your Mac features full AV1 hardware decoding.
   - If the label reads **Apple M1**, **Apple M2**, or any variation like Pro, Max, or Ultra, your Mac relies on CPU software decoding for AV1.
   - If the label displays an **Intel** processor name, your Mac uses CPU software decoding.

Knowing your chip generation helps you decide which video formats to choose when downloading media or configuring video players for travel.

## What is the real-world difference between hardware and software decoding?

To the human eye, a 4K frame decoded in hardware looks identical to the same frame decoded in software. Both pipelines execute the exact same decompression calculations and render the resulting pixels to your Mac display.

The difference lies entirely in power consumption, thermal dissipation, and processor overhead:

- **Hardware decoding (Apple's media engine):** the video goes to circuits built for decoding instead of the CPU cores. The CPU stays mostly idle, the Mac stays cool and the battery lasts.
- **Software decoding (CPU cores via dav1d):** The compressed bitstream must be broken down and processed by general-purpose CPU cores. Modern open-source software decoders like VideoLAN's [dav1d](https://www.videolan.org/projects/dav1d.html) use heavily hand-tuned ARM NEON assembly instructions to distribute the workload across multiple Performance and Efficiency cores. While an M1 or M2 Mac can decode 4K AV1 without stuttering, the CPU draws more power. On a MacBook running on battery, this increased energy consumption drains the battery noticeably faster.

If you are plugged into an AC wall outlet at a desk, software decoding on an M1 or M2 Mac is completely fine. But if you are watching video on a long flight without a power plug, understanding this power difference is essential.

## How do Safari, Chrome, and YouTube handle AV1 on macOS?

Web browsers handle AV1 differently depending on which operating system frameworks they use to decode streaming media.

YouTube uses AV1 for many videos, especially at high resolutions, when your browser and Mac can decode it. What you get depends on both:

1. **Safari** uses macOS's own decoders, so it plays AV1 on M3 and newer Macs, in hardware. On M1 and M2 Macs it gets another codec from YouTube instead.
2. **Chrome and Firefox** include the dav1d software decoder, so they can play AV1 on any Mac, at the cost of more CPU work where there is no AV1 hardware.

You can verify which codec YouTube is serving at any moment:

1. Open any popular 4K video on YouTube in your web browser.
2. Right-click anywhere on the video frame and select **Stats for nerds**.
3. Locate the **Codecs** line in the overlay panel.
4. If you see `av01.0...`, YouTube is feeding you an AV1 stream. If you see `vp09.0...`, YouTube is serving a VP9 stream.

## Why does QuickTime Player refuse standalone AV1 files?

QuickTime Player uses macOS's own decoders and file readers, which are strict:

- It plays AV1 only on Macs with AV1 hardware (M3 and newer).
- And only inside an MP4 or MOV file. AV1 in a WebM or MKV file gets the "not compatible" message on every Mac.

Much of the AV1 video you meet online comes in WebM or MKV. To watch these files, you need a player that pairs modern container demuxers with Apple's hardware decode APIs.

MacLC routes AV1 through VideoToolbox hardware decoding on M3, M4, and newer Macs, and uses the bundled dav1d engine on M1 and M2 for smooth playback without extra configuration.

## What should you do when downloading or playing AV1 videos?

As internet streaming platforms and media archives complete their migration to AV1, managing these files on your Mac is straightforward once you know your hardware capabilities.

If you own an Apple Silicon M3, M4, or newer Mac:

- AV1 is a great choice when you encode your own videos: small files, and hardware decoding when you play them.
- High-resolution streams in Safari are decoded in hardware.

If you own an M1 or M2 Mac:

- Playback is not a problem: players with their own decoder, MacLC among them, play AV1 files smoothly.
- When packing for travel or planning long playback sessions on battery power, prefer HEVC (H.265) files over AV1 when given a choice. Because M1 and M2 chips decode HEVC in hardware, your MacBook will run cooler and provide substantially longer battery runtime.

Match your files to your chip's hardware decoders and you get the same picture for less battery.

## Questions people ask

### Can an M1 or M2 Mac play 4K AV1 video?

Usually, yes, in an app with a software decoder such as dav1d (MacLC, VLC, IINA, Chrome, Firefox). It works the CPU harder than an M3 or newer would, so it uses more battery.

### Does the M3 chip have AV1 hardware decoding?

Yes. Apple added a dedicated AV1 hardware decoding unit to the Media Engine starting with the base M3, M3 Pro, and M3 Max chips, continuing across all M4 processors.

### Why does QuickTime Player fail to open some AV1 files?

QuickTime Player relies on macOS's own decoders: it plays AV1 only inside MP4 or MOV files, and only on Macs with AV1 hardware (M3 and newer). It never opens MKV or WebM files.

### How can I check if YouTube is streaming AV1 to my Mac?

Right-click any playing YouTube video and select Stats for nerds. Under the Codecs line, look for an identifier starting with av01, which confirms an active AV1 stream.
