Opening Melvec on macOS​

Some users may encounter a macOS security warning when trying to open Melvec after downloading the .dmg file:

“Melvec” cannot be opened because Apple could not verify it is free of malware.

This is macOS Gatekeeper protecting your system. Melvec is signed with Apple’s Developer ID and notarized, but downloaded apps often trigger this extra verification step.

Step-by-Step Solution​

1. Install Melvec from the DMG​

  • Double-click the downloaded .dmg file to mount it.
  • Drag the Melvec app into your Applications folder (recommended) or onto your Desktop.

2. Open the App (Quick Method)​

  • Right-click (or Control-click) the Melvec app in your Applications folder.
  • Select Open from the context menu.
  • In the dialog that appears, click Open.

3. Open via System Settings (Alternative)​

  1. Attempt to open Melvec normally (double-click) and click Done on the warning.
  2. Go to  → System Settings → Privacy & Security.
  3. Scroll down to the Security section at the bottom.
  4. Find the message about Melvec and click Open Anyway.
  5. When prompted again, click Open.

After this one-time approval, you can launch Melvec normally by double-clicking it.

Additional Tips​

  • Best Practice: Always copy the app from the .dmg to your Applications folder before launching.

  • Redownload: If the issue persists, delete the current .dmg and redownload it from our official source.

  • Terminal Workaround (for stubborn cases):

    xattr -d com.apple.quarantine "/Applications/Melvec.app"

Melvec app is not auto updating​

Right now, melvec app does not support automatic updation. We may support it in subsequent versions.

Melvec app is crashing or not working.​

The possible reasons are: - Your computer's operating system is not supported.

  • Your computer's hardware is not supported.
