How to update DATATRAVELER LOCKER G2 on my macOS Big Sur Version 11.5.1

Greetings frederic143, 

It sounds as though you’re wanting to update or use a DataTraveler Locker+ G2 USB drive with your MacBook Pro. You’ve come to a great place for help! We see you’ve come from the 32-bit app compatibility with macOS High Sierra 10.13.4 and later article.

To confirm, is the Mac not recognizing that the drive is connected? For example, if you go in to Finder after connecting the external drive does it not appear, or are you having a different issue? Please provide as much information as possible to help guide us through the right troubleshooting steps. 

We look forward to your response!
