Despite possible vulnerabilities on PPTP connection claimed by Apple, it's very confusing that I can't connect to my working PC in my company any more since my company network is still implementing PPTP connection. I think it would be great to me if Parallels Toolbox add this feature as a supplement to what mac OS is not supporting. With this feature added, I guess many mac OS users (and Parallels users as well) could benefit from it. My suggestion might sound silly, but it's really what I hope in this moment. Thanks for reading.
