Made for macOS

Captions made on your Mac, not in someone else's cloud

Captixa runs on your Mac, with a separate build for Apple silicon and for Intel. Transcribe offline with local Whisper, or with Groq or OpenAI where only the audio is sent.

Styling, editing, preview and export all run on your machine, and your footage stays exactly where it is.

On Mac, Captixa gives you

  • Separate builds for Apple silicon and Intel
  • Local Whisper runs fully offline, no key needed
  • MP4 at Source, 720p, 1080p, 2K or 4K, plus SRT
  • The same license works on Windows
Why Captixa on Mac

Everything a caption needs, on your own computer

Apple silicon and Intel

Pick the build for your Mac: M1 or newer, or an Intel-based Mac.

Offline transcription

Download a local Whisper model once, from 75 MB to 3 GB, and transcribe with no internet and no API key.

Safe zones for every app

See where TikTok, Reels and Shorts put their buttons, and move captions clear in one click.

Keys stay on your Mac

Groq, OpenAI and Gemini keys are stored on your computer only and used to call those providers directly.

Projects that save themselves

Autosave after every edit. Projects point to your footage and never make a copy of it.

Install guide

How to install Captixa on Mac

Step by step, including what to do when Mac shows a security prompt for a new app.

Install on your Mac About 2 minutes
  1. Download the right file. Apple silicon Macs need the file ending in aarch64.dmg; Intel Macs need the one ending in x64.dmg. Not sure? Apple menu, then About This Mac: it says Chip: Apple M… or Processor: Intel.
  2. Open the .dmg file and drag Captixa into the Applications folder in the window that opens.
  3. Eject the installer. Right-click the Captixa disk on your desktop or in Finder and choose Eject.
  4. Open it the first time with a right-click. In Applications, right-click (or Control-click) Captixa, choose Open, then Open again. After this it opens normally.

If macOS says the app "is damaged and can't be opened", nothing is wrong with it. Follow the Terminal fix below.

Fix "Captixa is damaged and can't be opened" One Terminal command
  1. Make sure the app is in Applications. The fix only works once you have dragged it there.
  2. Open Terminal. Press Command and Space, type Terminal and press Return.
  3. Paste this command and press Return. It removes the "downloaded from the internet" mark macOS puts on new apps. 
    xattr -cr "/Applications/Captixa.app"
    If nothing appears after you press Return, it worked. Terminal stays quiet when a command succeeds.
  4. Open Captixa from Applications. From now on it opens like any other app.

Why this happens: macOS marks apps that are not yet notarized with Apple as unknown downloads. The command only removes that mark. It does not change the app or turn off your Mac's security.

Troubleshooting

Fixes for common Mac problems

Most of these are one-time security prompts, and each takes a minute to fix.

"Captixa is damaged and can't be opened"

The app is fine. Move it to Applications, then run this in Terminal:

xattr -cr "/Applications/Captixa.app"

"Apple cannot check it for malicious software"

Right-click the app in Applications and choose Open, then Open again. Or open System Settings, then Privacy & Security, and choose Open Anyway.

"Operation not permitted" in Terminal

Run the command with sudo. It asks for your Mac password, and nothing appears while you type it. That is normal.

sudo xattr -cr "/Applications/Captixa.app"

The app closes as soon as it opens

You probably have the build for the other kind of Mac. Delete it from Applications, download the file that matches your chip (aarch64 for Apple silicon, x64 for Intel) and install again.

Update

Download the new .dmg, drag Captixa into Applications and choose Replace. Your settings, API keys and license stay in place.

Uninstall

Drag Captixa from Applications to the Trash, then empty the Trash. Your video files are never touched.

FAQ

Captixa on Mac, answered

Something else on your mind? Contact us and a real person will reply.

Does Captixa work on Mac?

Yes. Captixa runs on Windows 10/11 and macOS, with a build for Apple silicon and a build for Intel Macs.

Which Mac version should I download?

Choose Apple silicon if your Mac has an M-series chip, and Intel if it has an Intel processor. Check under Apple menu, then About This Mac.

Why does macOS say the app cannot be opened?

macOS flags downloaded apps that are not yet notarized with Apple. Right-click the app and choose Open. If it says the app is damaged, run xattr -cr "/Applications/Captixa.app" in Terminal.

Does export use my Mac's GPU?

Not yet. On a Mac, Captixa exports on the CPU. It takes a little longer for 2K and 4K, and the video comes out the same.

Does it work offline?

Yes, with local Whisper: transcribing, styling, editing and exporting all work without internet. Translation and Roman-script conversion need a connection.

Can I use my license on a Windows PC too?

Yes. A Pro license works on macOS and Windows, on one computer at a time. Switch from your dashboard whenever you like.
