For another way to open AVI, Mac users can convert files to QuickTime MOV or MP4. To do so, you can install a video converter program or use an online AVI file converter. Desktop conversion software works more quickly and allows you to convert multiple AVI files simultaneously. On the other hand, online converters like Zamzar and CloudConvert can only convert 1 or 2 files at the same time.
Desktop Video Converter App: Movavi
Movavi is a convenient converter app for Mac. It can help you view AVI on Mac by converting your file into another Apple-friendly video format.

Option 3: Find the Right Codec to Play AVI on QuickTime
As described on the official Apple website, QuickTime may require additional components to play additional media types. Most of these are known as codecs and can be downloaded, in order to enhance the functionality of QuickTime.
When looking for an AVI codec for Mac, one of the options you can consider is 3ivx MPEG-4. This codec supports all video files with the AVI extension and can play them on QuickTime Player. To use the codec, make sure you download it from the official website. It comes with a free trial and subsequently requires a license.
- It enables you to play most AVI, MP4, M4A, 3GP, and MOV files
- Produces higher quality video than other decoders.
- Some users may find the installation more complex
- It’s not free.
Option 4: Open AVI Using a Plugin or Add-On for Your Player
Perian is a free, open-source, QuickTime component. It allows QuickTime to play several popular video formats that are not supported natively by macOS. These include AVI, DivX, and XviD, among others.
Unfortunately, the Perian software has been discontinued, so there are no new releases available, or support. As a result, it doesn’t work with the latest versions of QuickTime. The team behind Perian recommends using NicePlayer instead. It’s another open-source solution to opening AVI files on Mac, however, its latest release dates back to 2014.
- It empowers QuickTime to play various unsupported video files, audio, text, and container formats.
- Installation is not straightforward if you’re not a more advanced user
- Some plug-ins solutions are not being updated by their creators
- Make sure you download any components from the official websites to avoid risks.
Option 5: Fix a Corrupt AVI File to Open it
If you still cannot play AVI on Mac after trying a suitable player, converting your AVI file to MOV, or installing the proper codec, your AVI file might be corrupt. And a corrupt file cannot be played even with a free AVI player for Mac. Luckily, most errors are due to damages to the AVI file index which accompanies your video, not the actual video.
Thus, you can try to repair it using AVI video repair software. There are apps specifically designed for this purpose, both free and paid, as well as online services. Some players such as VLC can play damaged files without actually modifying the source file.
- Repair software can salvage an unplayable AVI file
- Some solutions fix low-level corruption issues, while others can repair more severe problems.
- Some repair software may incur hidden charges
- Beware of adware or redundant software versions.
What Is an AVI File?
An AVI file is a format that uses the .avi file extension. It was introduced in 1992 as the standard video format for the Windows operating system. AVI is saved as part of the Audio Video Interleave (AVI) multimedia container, which acts like a box containing both audio and video. The data in this container can be encoded using various codecs, e.g. DivX and XviD.
What Is a Codec?
A codec is a piece of software that encodes or decodes data. Each codec contains an encoder to compress files, and a decoder to decompress them. The compression can be lossy or lossless. Lossy compression compromises quality to produce a smaller file, while lossless preserves quality, producing larger files. Some popular video codecs include DivX, XviD, MPEG-2, MPEG-4, HEVC/H.265, and H.264. If a video player fails to open a file, it may lack a particular codec.
