How do you install the Concat video editor on macOS?
- Download the .dmg that matches your chip from the official Concat GitHub release.
- Open the .dmg and drag Concat into Applications.
- If macOS says Concat cannot be opened or is damaged, run the Terminal command below once.
- 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.appHow 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.dmgThe official hashes are in SHA256SUMS on the release page.
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.
What should you set up after installing?
Open Settings and download the models for the features you plan to use. Captions need a Whisper model, text to speech needs a voice model, and background removal fetches a small model the first time you use it. See auto captions and fixing text to speech for the details.
