Our company currently has a MacOS VPN app which contains two network extensions: a packet-tunnel provider and an app proxy provider. Being network extensions, these must be signed by Apple before being used by our customers, and distribution is limited to the Mac AppStore (versions downloaded from there can be pushed using MDM). However, unlike our iOS version, there is currently no way to beta-test our app, because there is no enterprise version or TestFlight-equivalent for Mac that allows Network Extensions.
I understand that with MacOS Big Sur, there have been revisions to the Apple Business Manager that will allow for greater flexibility of distribution to corporate clients. I have been unable to find out whether or not network extensions are supported in this. So my questions are: (1) is distribution of network extensions on the Mac platform available now for beta-testers? (2) If so, what is the procedure for doing so? What do I, as an App Developer with an existing product, have to do to make this possible?
