"Legacy System Extension" will be incompatible with a future version of macOS

Two of our staff have reported seeing a popup warning them that a "Legacy System Extension" will be incompatible with a future version of macOS. Now they are afraid to upgrade macOS and possibly not be able to connect by VPN.

We are running Firebox System Manager Version 12.6.1-B62167.

  • Which VPN type are you using?

    Perhaps this?

    Hi @sysadmin_bfa
    If the customer is already on the latest version of MacOS X, they're likely seeing that related to Big Sir (which is the upcoming version.) An update to the SSLVPN and IPSec VPN apps are planned, but a final release candidate to test against hasn't yet been released by Apple. Apple is expected to release this soon.

    I would suggest against customers running beta software in production environments unless they are OK with the risks of incompatibility that come along with it.
