Description

This article describes a change where the users cannot configure host check for the new MacOS Tahoe 26 in the SSL VPN configuration on FortiGate.

Scope

FortiGate.

Solution

Before v7.4.10, FortiGate does not support MacOS Tahoe 26 as an OS checklist for the SSL VPN.

config vpn ssl web portal
    edit "full-access"
        set tunnel-mode enable
        set ipv6-tunnel-mode enable
        set web-mode enable
        set ip-pools "SSLVPN_TUNNEL_ADDR1"
        set ipv6-pools "SSLVPN_TUNNEL_IPv6_ADDR1"
        set os-check enable
        config os-check-list "windows-7"
        end
        config os-check-list "windows-8.1"
        end
        config os-check-list "windows-10"
        end
        config os-check-list "windows-11"
        end
        config os-check-list "macos-mojave-10.14"
        end
        config os-check-list "macos-catalina-10.15"
        end
        config os-check-list "macos-bigsur-11"
            set minor-version 0
        end
        config os-check-list "macos-monterey-12"
            set minor-version 0
        end
        config os-check-list "macos-ventura-13"
            set minor-version 0
        end
        config os-check-list "macos-sonoma-14"
            set minor-version 0
        end
        config os-check-list "macos-sequoia-15"
            set minor-version 0
        end
    next
end

Starting from v7.4.10, MacOS Tahoe 26 is included in the OS checklist for the SSL VPN.

config vpn ssl web portal
edit <name>
config os-check-list "macos-tahoe-26"

end
next
end

The issue will be fixed in the following version.

v7.4.10 (scheduled to be released in January 2026).

The timeline for firmware release is an estimate and may be subject to change.
