Hi All,
I have a question. Just after the software upgrade from Catalina to Big Sur, my mac (Macbook Air 13-inch, Early 2015) stopped mounting any usb external discs. Doesn't matter, if it's an usb ssd card reader, usb stick, or external hdd. Does anyone have a similar problem, and any possible solution?
Thanks
MacBook Air 13″, macOS 11.0

Have you rebooted and tried again?
You can Try resetting NVRAM/PRAM http://support.apple.com/kb/ht1379
when you do that I get back an error that says "Could not mount “disk2s1”. (com.apple.DiskManagement.disenter error -119930868.)"
Doesn't work on my new iMac 2020. Interestingly my external mounts immediately on my MacBook running same version of Big Sur.
Mine eventually worked (the external hdd and usb stick), but had to replace the usb micro sd card reader
I'm not particularly tech minded. How do I do this?
me also come up with the same problem :
Could not mount “disk2s2”. (com.apple.DiskManagement.disenter error -119930868.)
I need assistance
Didn't work for me unfortunately.
It's ridiculous. This should have been fixed without any of us having to be IT experts, which I am not!
Big Sur - External disc not mounting
