VPN connections drop for multitudes of reasons originating "out there". I found out about the existence of a MacOS "feature" that silently breaks the connection upon being up for 24 hours.
Note --- it is the VPN that drops -- not your internet connection.
After expressing my irritation to Apple about their sabotage --- my VPN service came up with a beta Mac app (HideMe.app) that would take care of it. That *looked* good, but gave me ZERO speed connections.
After checking out the assorted options -some waaaay to geeky for me to work -- I snagged this one. Simple. Clean instructions in the help files.
It is an App Store item -- which means it won't/ cannot pause your online programs when the VPN breaks. It does take a few seconds to re-establish a VPN connection --- which is a few seconds of privacy exposure.
Frankly, that is the only reason that kept me from giving it 5 stars.
