Installation

Plate runs in the browser — no install needed. Open app.plate.video in Chrome and you’re in. Projects save as .plate files on your machine.

Other browsers can open Plate but some features will be limited or missing. Chrome is fully-supported.

For a more self-contained experience, download the macOS desktop app from plate.video. Apple Silicon only for now — Windows support is coming soon.

First launch on macOS

Plate isn’t signed with an Apple Developer certificate yet, so macOS will show a warning the first time you open it. Here’s the one-time unlock:

1. Download plate-0.1.0-arm64.dmg from plate.video.
2. Open the .dmg and drag Plate to your Applications folder.
3. Double-click Plate in Applications. macOS will show a dialog saying Plate can’t be verified — click Done.
4. Open System Settings → Privacy & Security.
5. Scroll down to the Security section. You’ll see “‘Plate’ was blocked to protect your Mac.” Click Open Anyway.
6. Confirm when prompted. Plate launches.

From here on, Plate opens normally like any other app. Code-signing is in the works, so future releases will skip this step.
