I’ve been using a VPN for privacy particularly on wifi networks (Starbucks). I’ve been using Tunnelblick for a while, but in the most recent releases on Yosemite it has become pretty unstable. Seems to hang and then OpenVPN underneath breaks and network access stops. So I’ve flipped to privateinternetaccess.com’s own VPN utility. I’ve no idea what it is actually doing, but seems to work.
For grins, I’ve also turned up all the encryption settings so went from AES-128 to AES-256, authentication from SHA1 to SHA256 and the handstand from RSA-1024 to RSA-4096.
The main issue right now is that it doesn’t seem to repoint the DNS servers properly
