Hello there,
i don't know about macos client. but surely windows native client will not
work.
here is example configuration psk + eap-mschapv2 with radius
this works with ios native client.

    vpn-pskeap {
        local_addrs  = $$locaip

        local {
            auth = psk
            id = $$leftid
        }

        remote {
            auth = eap-radius
        }

        children {
            updown = /usr/lib/ipsec/_updown iptables
            esp_proposals =
aes128-aes192-aes256-sha1-sha256-sha384-sha512-ecp256-ecp384-ecp521-modp2048-modp3072-modp4096-modp1024
            dpd_action = clear
            close_action = clear
            ike_lifetime = 45m
            ipcomp = yes
            vpn-pskeap {
                local_ts = 0.0.0.0/0
            }
        }

        version = 2
        proposals =
aes128-aes192-aes256-sha1-sha256-sha384-sha512-ecp256-ecp384-ecp521-modp2048-modp3072-modp4096-modp1024
        mobike = yes
        fragmentation = yes
        encap = yes
        dpd_timeout = 60
        dpd_delay = 25
        unique = never
        pools = radius
    }
