Q: FCPX Importing Issue

HHow did you update? What exactly are you doing and what happens when you do it? What's the media?

Does it ever finish loading the media? Or is it stuck trying to load the card?

Try trashing prefs. Make a new admin user and try mounting the card in there. Don't open FCP. Does the card mount and can you access the content?

Did you try a new user? Sounds like your card reader needs a new driver for Sierra.

You probably would need to check with the manufacturer.

Same issue for me as well. I am not finding any updated drivers online, so stuck now. This is very frustrating. I should have known better than to think that Apple would release a new OS that actually works with Apple software....

WWhat Apple software? The only drivers Apple makes are for the built in card readers. It has nothing to do with SxS card readers, which is the manufacturer's responibity. The OS software has been available to developers since June.
