Just upgraded to OS X El Capitan. I had installed the USB driver and it worked fine for 2-3 days. The driver has now stopped working for as-yet unexplained reasons. I tried to connect via the 2.4G Serial connection, but that doesn’t seem to work either (did before).
I have followed the processes listed to reinstall the USB driver with no success, so I’m at something of a dead end right now. My biggest concern is that I had planned to use the mBot for teaching programming classes, but I don’t want to subject the kids to a lot of frustration because they can’t get their mBots connected on a reliable basis.
OS X: 10.11 (15A284)
Update: The issue seems to be that the WCH341 doesn’t have a signed driver and El Capitan (OS X 10.11) seems to be much pickier about that than Yosemite (OS X 10.10), likely due to the XCodeGhost attack. Even trying the link to set the operating system in developer mode doesn’t seem to work.
Any thoughts / guidance are appreciated.
