M2 Film - Metadata Editor for Film Photographers

Installation Instructions

⚠️ Why Your Mac Will Block This App

I'm a bum who doesn't have an Apple Developer account ($99/year) to "sign" this app properly. So macOS will quarantine it and say it's "damaged." The app is completely safe — it's fully open source so you can inspect every line of code.

Step 1: Download and Install

Download the .dmg or .zip file above
If using DMG: Open it and drag M2 Film to Applications folder
If using ZIP: Unzip it and drag M2 Film.app to Applications folder

Step 2: Remove the Quarantine Flag (REQUIRED)

macOS will block the app from opening. You MUST run this Terminal command:

Open Terminal and paste this:

xattr -cr "/Applications/M2 Film.app"

Press Enter. No output = success. This removes the quarantine flag.

Step 3: Launch

Now open M2 Film from Applications. It should launch normally. Future opens won't require any special steps!
