Hi Team,
I have an Acer Connect D5 Dongle (A very small 5G USB-C Modem). When I plug in to Mac Mac (Sonoma 14.5b) The Dongle is perfectly show in system profiler and IORegistryExplorer like an old Sierra WWAN or Novatel Merlin.
But I have an issue in Network pane of System Pref; the modem do not appear in network.
Any idea to help me ? Thanks !
bDeviceClass = 0xef, which means "Miscellaneous".
This isn't a standard communications device so the in-box drivers on macOS don't know what to do with it. It needs a driver from the vendor, Acer. Acer's web site does not claim macOS compatibility for this device, so I wouldn't hold your breath.
Incidentally, this isn't an appropriate question for this forum, which is for questions relating to developing software for Apple platforms. End user support forums are elsewhere.
Thank, but I works whit a 10.12 and less.. I Suspect a ECM Driver issue.
