Two small Wireguard frustrations on Mac & Apple iOS

[Jasper Knockaert]

Hi

Just one other issue with the MacOS client. When you have multiple users 
on the same computer (say user A and user B) user A can import a 
WireGuard config in the client. Then another user B can see the config 
name, but cannot modify or connect because the required keys are in the 
Keychain of user A. So far all is fine. But user A may specify the 
config to connect on demand (basically upon login). Then when logging in 
as user B, WireGuard will still try to connect without having access to 
the connection settings (because they are stored in the keychain of user 
A). This causes an endless loop, which should be avoided.
