Installing ViBatchte

Your browser may warn you

Chrome and some other browsers may say that the file is rarely downloaded. That is about popularity, not about contents: ViBatchte was released recently, and it has not been downloaded many times yet. Safari gives no such warning.

Below are the checksum and the antivirus report, so that you can check the file yourself.

Check the file

In Terminal, run this against the disk image you downloaded:

shasum -a 256 ~/Downloads/ViBatchte.dmg

It prints one line. The long value at the front must match the checksum below, character for character.

Installing

ViBatchte comes as a disk image. It opens as a window with the app inside — but that window is only the package, not a place to run the app from. Launched from there, ViBatchte either will not start, or runs once and disappears when the image is ejected. Copy it to Applications first; every step below starts from there.

1. 01

   Open the disk image if it did not open itself. Safari opens downloaded disk images automatically; in other browsers, double-click the file.

2. 02

   Drag ViBatchte from that window into the Applications folder in the Finder sidebar. Then eject the disk image — the copy in Applications is the one you keep.

3. 03

   Open ViBatchte from Applications. macOS will refuse and say that Apple could not verify the app is free of malware. This is expected: the app is signed, but not yet notarised with Apple. Press Done.

4. 04

   Open System Settings → Privacy & Security and scroll to the bottom. There will be a line about ViBatchte and an Open Anyway button — press it and confirm with your password.

5. 05

   One more warning appears with an Open Anyway button. Press it — the app opens.

This is only needed the first time. After that ViBatchte opens with an ordinary double-click.

If it still will not open: open Terminal, run

xattr -cr /Applications/ViBatchte.app

and repeat step 3.

Why macOS asks

Notarisation with Apple costs money and is issued to a company. It will happen. There is nothing hidden in ViBatchte: the checksum and the antivirus report above are there so you can see that for yourself.

Licence

ViBatchte runs in full for 100 days, with no sign-up. The ViBatchte license window opens when the main window first appears: press Start free trial, or enter a key if you have one. To bring the window back later, click the ViBatchte name at the top left of the app.

The processing engine and the libraries inside ViBatchte come under their own licences: third-party licences

The second first launch

Once macOS lets ViBatchte through, the app has one more thing to do before it can work: it downloads its processing engine, ffmpeg. The window reads Preparing ViBatchte for first launch and shows the progress. This needs an internet connection, and it happens only once.

The download is about 42 MB — roughly half a minute on a 10 Mbit/s connection — followed by a few seconds of checking and installing. The app verifies the checksum of what it received before unpacking it. Then the main window opens, and later launches skip this step entirely.

Without the engine ViBatchte cannot process anything, so it stays on this screen until the download succeeds. It is not a broken app — it is a setup that has not finished. If the download fails, the screen says why and offers Try again.

If it keeps failing: the engine comes from github.com, so check that a VPN, a firewall or a corporate network is not blocking it, and that there are about 150 MB free on the disk. Then press Try again.

From then on everything happens on your Mac. ViBatchte processes files locally, and your files never leave the computer.
