macOS firewall blocking web browsing after upgrading to Sequoia

After upgrading to macOS Sequoia, users have reported issues with the OS firewall blocking web browsing. This problem appears to affect various browsers, and users have noted that there is no straightforward way to adjust access settings through the firewall interface. To resolve this, users can utilize the command line interface (CLI) tool located at /usr/libexec/ApplicationFirewall/socketfilterfw to modify firewall settings. By adding their web browser to the firewall's allowed list, users can restore internet access. However, some applications, such as nvm and Spotify, may still experience issues, necessitating similar adjustments for each affected app. Users can also disable the firewall entirely as a less secure workaround. For those unable to locate certain applications like Universal Control, a command can be run to find their paths, allowing users to add them to the firewall as well. The community has engaged in discussions about these issues, sharing solutions and theories regarding the underlying causes of the firewall's behavior.
