Fatal Error restarting docker daemon on install

[Jean-Baptiste-Lasselle]

so I :

• by some chance once get the tap interface after running the install script, and could then use the tap up script, add the route, and ping my containers
• after some minutes playing with the containers I realize I cannot ping them anymore, although the tap interface was still ther (but noticed IP address of tap, configured as gateway, had changed -> but there even changing the route with new ip address dud not solve the problem)
• many times uninstalled reinstalled (plus addituonal steps) , results :
  • almost every time I reinstall, a fatal error occurs restarting docker daemon , giving this error message in a dialogbox :

2021-04-18T04:57:03Z dockerd time="2021-04-18T04:57:03.299215681Z" level=error msg="Handler for GET /v1.41/services returned error: This node is not a swarm manager. Use \"docker swarm init\" or \"docker swarm join\" to connect this node to swarm and try again."

• no tap interface ever appears with ifconfig

I understand that there's something about mac not supporting tap interfaces anymore, and know that community would have provided a solution if it had been possible,

Honestly macbook sucks for anything technically serious : just good at media and secretrary work , no respect for GNU/linux, this would never have happened on debian, going back to debian, keeping mac for dumb slack youtube google meet and google slides, and invoices
