Box Drive's system extension failed to load. Please make sure it has been enabled in System Preferences > Security & Privacy and then restart your computer

Hi Clint,

Welcome to the Box Community!

Can you try to uninstall and then reinstall Box Drive and see if that helps resolve this for you?

If the issue persists, please let us know and provide what macOS version are you running so we can further troubleshoot.

Thanks for your participation in the forum!

Best,

Same symptom with my laptop. After it update to Big Sur 11.6, Box drive no longer load and I have checked its extensions had enabled. 

Laptop information:

MacBook Pro (15-inch, 2017)

Processor 2.9 GHz Quad-Core Intel Core i7

BTW, uninstall Box also tried. After uninstall, BOX requested to re-login then same symptom again.
