However in the network settings of my iMac, FP2 does not show up.
In contrats when I connect my old iPhone4 allowing USB-tethering, the iPhone4 pops up as service.
How can I tell the iMac that it should use the FP2 as network connection ?
Thanks for your help.
I found two closed similar topics, one of them marked as solved without presenting the solution:
It is compatible and have just tried upon FP2 17.10.1 (not sure about Open OS). Go to Settings > *** More (below Data usage) > Tethering & portable hotspot > Enable USB tethering
For the small minority of Mac OSX users utilising USB tether with the release of Catalina 10.15.5 HoRNDIS feature will cease to work, although to be fair Apple have been prompting that it would be disabled at this release.
There is a 'workaround" to keep this feature working, although it would require “trusting” .pkg signed by third-party. Subject is discussed in more detail here, although a “restart” is required after installation: https://github.com/jwise/HoRNDIS/issues/102#issuecomment-541237232
