While installing CF2021 on MacOS Big Sur 11.5.1, users are getting this error message –  “libjvm.dylib” cannot be opened because the developer cannot be verified. Even after Allowing this from Security, it does not let users install it.

Here are a few simple steps to install it.

Eject the current installer.

1. Launch the terminal and type this command xattr -rc <ColdFusion2021_xxxx.dmg file location>.
2. Once you run this command, Run the installer and see if that works.
3. In case, you will still see the issue. Make sure to unmount the CF installer in Mac and then run the command and try to install it again.
4. Go to Preferences/Security& Privacy/General, and “Allow anyway” shows up.  Click on continue. It will work.

I hope these will help you install CF on MacOS. Feel free to leave a comment, in case you face any issues.

P.S. – CF2021 does not support macOS Monterey.
