Unable to Export Network Connection in El Capitan
I have a VPN connection for my work setup in Network Preferences. Any time I get a new Mac, the VPN connection is the only thing that never gets copied over by Migration Assistant when I move things over from my old Mac to the new Mac. What I've always done in the past is select the VPN connection on one of my Macs (I have a MBP and an iMac), export it (usually to a USB thumb drive), and then import it on the new Mac because I don't have all the settings to set it up manually again (one of the network guys at work set up the VPN connection for me years ago).
I just got a new MBP, and after everything got copied over I went into Network Preferences - and as usual, the VPN connection wasn't there. I went to my old MBP to export it, and when I selected the VPN connection and tried to export it I couldn't. The Export Configuration menu item was greyed out. So I thought maybe something funky was going on with my old MBP, and tried to do it from my iMac. Same thing happened on my iMac - the Export Configuration menu item was greyed out. All of them have El Capitan on them. It doesn't matter what connection I select under Network Preferences (even non-VPN connections, and even on my new MBP), the Export Configuration menu item is greyed out - it's not just with the VPN connection. Import Configuration is there and is selectable - if I had a configuration to import. Is this some bug in El Capitan, or what the heck is going on?
