I have recently downloaded the VirtualBox virtual machine software on my MacBook air, in hopes to play Overwatch. Every time I try to download the Battle.net desktop app, it says I have encountered a network error while receiving an update. I am connected to the internet through my host computer.

Hey, doubledecaf! Virtual Machines (including Boot Camp/Parallels) are not officially supported by Blizzard. Blizzard Technical support do not offer troubleshooting for VM or bootcamp. If you are experiencing issues on a virtual machine, it may be best to refer to the VM’s support or a respective forums community for further assistance.
Activating a VPN allows you to download Battle.net through virtual machines.
