Sen2cor running error


having error when running sen2cor file for MacOS.

Verifying archive integrity… All good.
**Uncompressing SEN2COR 02.09.00 100% **
install_name_tool does not exists…
please install install_name_tool and make sure it can be found from PATH

Can you please explain what is install_name_tool and how can I install it? Thanks in advance.

install_name_tool is a macOS developer utility. Either you have not installed the Apple Developer Command Line Tools or your PATH environment variable is not set correctly (you may need to log out and back in after installing the command-line tools).
