OSC ports in Max8/Live10

arne's icon

I'm using OSC to communicate between various M4L devices on different ports.
When I edit one of these devices through Max8/Live10 on a Mac (Sierra), the port no longer receives data. And after editing, I need to quit Max before it functions again in Live.
This doesn't happen when editing the same devices on Windows10.
I'm guessing that my Mac is not releasing the ports after closing the edited patch, but I'm no network expert (and couldn't find any messages to udpsend that would do so).

Any thoughts would be appreciated.
