Is there any alternative to tuntap osx?

[im-kulikov]

1. Apple M1 doesn't support tuntap-osx (not my case)
2. Apple deprecates tuntap kexts (all cases)
3. There're some bugs that would not be fixed in tuntap-osx (latest update 2015 year) and sometimes it cases reboot of macOS 11 (x64 cpu) and system removes tun/tap kexts and plist files of tuntap-osx

So, is there any alternatives for tuntap-osx?

We haven't been able to find a drop-in equivalent for our M1 machines. With that said, a good alternative has been setting up an ovpn container to run in docker and using Tunnelblick to connect with our needed CIDR ranges. Not as ideal as a proper host bridge but its pretty close.
