Pf Configuration Incompatible With Pf Program Version [work] -

: If you recently upgraded your kernel, ensure all associated system binaries were also updated to match the new version.

PF is a highly efficient, kernel-level packet filtering system. Because it operates deep within the operating system kernel, the syntax used in the configuration file ( /etc/pf.conf ) must perfectly align with the features compiled into the active kernel module. Why the Error Occurs

The kernel/userland API for PF can change subtly between releases. When an old pfctl binary attempts to load a ruleset into a new kernel with updated data structures, the kernel rejects the ioctl commands, returning the incompatibility error.
