I repeatedly downloaded the Device Manager app to my Mac; rebooted, rebooted and rebooted again; and used multiple cables. All to no avail. In the end I had an exchange of emails with a really helpful guy in Support. At the end of a fruitless process of elimination, he asked my what USB ports I had on my Mac, because - unbelievably - the camera apparently won't connect over anything other than USB 2.0!!!
I found this hard to believe considering my Mac dates all the way back to mid-2012 and yet still utilises USB 3.0, but I thought I'd better check. Luckily, I have an even older computer that I was able to hook the Sena up to and, sure enough, I found that by using a USB 2.0 port the camera was immediately recognised and the firmware was then successfully updated.
I'm still completely dumbstruck, but really just wanted to somehow confirm with other users that this is in fact correct. Or, perhaps, it's just a Mac issue and not something that affects PC users?
Puzzling, to say the least, as the 10C Pro has only just been released and USB 3.0 was introduced (I believe) around late 2011/early 2012!
