Hey there! 👋

The issue you're seeing is due to Apple's stricter Gatekeeper restrictions in newer macOS versions. No worries though - here's how to fix it:

Open Terminal (Applications > Utilities or Cmd + Space -> "Terminal") and run:

cd ~/Downloads  # or wherever your app is
xattr -d com.apple.quarantine Comet.app

That'll remove the quarantine flag that's blocking the app. After that, you should be able to just double-click to open it normally.

If your app is somewhere else or has spaces in the name, use the full path:

xattr -d com.apple.quarantine "~/Downloads/Comet.app"

You can verify it worked by running:

xattr Comet.app

If you don't see com.apple.quarantine listed anymore, you're good…
