Python support is deprecated with the newly released macOS version 12.3 (Monterey). The APM firewallcontrol script was written in Python, and no Python is provided in the macOS version 12.3. When a supported version of Python is not present , the firewall will not be active and the system posts the following message in /Library/Logs/F5Networks/f5fwctl.log: env: python: No such file or directory


The firewall control service does not run; it's completely blocked. This occurs because there is no Python support provided in macOS 12.3.


-- Locked Mode is enabled in any Edge Client version. -- The client's operating system is upgraded to macOS 12.3.
