- If you have the IM installer files in a macOS folder like Downloads or Documents, move them to a folder that you created manually in a non-special location, like the root of your home directory (for example: ~/installers).
- Open the Terminal application.
- cd to the RPT_SETUP directory.
- Run the command: sudo xattr -rcs .
This command removes the extended attributes for all the files under the current directory. Some of these attributes are preventing the installation. Since these attributes are not required for the installation, it is safe to remove all of them. - Enter your sudo password.
This screen capture shows the previous steps: - Verify that all metadata was stripped by using this command:
sudo xattr -lr .
This command returns no output if the metadata was successfully stripped. If there is output, that means all metadata was not stripped. Do not proceed to the next step until all metadata is stripped. - Go back to Finder and run Install.app.
- IM now starts and you can proceed with the installation.
