Open the Apple menu and choose About This Mac. If the Chip line says Apple M1, M2, M3 or later, take the arm64 .dmg. If it says Intel, take the x86_64 .dmg.

## How do you install the Concat video editor?

1. Download the .dmg that matches your chip from the official Concat GitHub release.
2. Open the .dmg and drag Concat into Applications.
3. If macOS says Concat cannot be opened or is damaged, run the Terminal command below once.
4. Open Concat from Applications, then download caption and voice models in Settings.

## How do I fix “Concat can’t be opened” on Mac?

macOS puts a quarantine flag on apps downloaded from the internet and refuses unsigned ones. The Concat README gives this command to clear the flag for the Concat app only:

```
xattr -dr com.apple.quarantine /Applications/Concat.app
```

## How do you check the download?

Swap arm64 for x86_64 if you took the Intel build, then compare with SHA256SUMS.

```
shasum -a 256 ~/Downloads/Concat-0.2.7-macos-arm64.dmg
```

## Does the Concat video editor run on Intel Macs?

Yes. There is a separate x86_64 build for Intel Macs alongside the arm64 build for Apple silicon. Apple silicon Macs will run the AI features faster.

## Questions people ask

### Is the Concat video editor on the Mac App Store?

No. Concat for Mac is only published as a .dmg on GitHub.

### Is the xattr command safe?

It only removes the download quarantine flag from the Concat app folder. It does not change system security settings for other apps.

### Is Concat a good free iMovie alternative on Mac?

For social video it can be. Concat adds local auto captions, text to speech and background removal, which iMovie does not offer. iMovie is more polished and signed by Apple.
