When trying to start the process the BCA stops me with the message "External Storage Device attached". I've unmounted and physically disconnected everything but the mouse and the Internet but I still get this message. Any idea what is going on?
iMac 27", macOS 10.15
Disconnect all external devices, except your BT Keyboard/Mouse/Trackpad.
Run
and retry BC Assistant.

What is the year/model of your Mac (do not post the serial number)?
I bought it last year, top of the line iMac.
Thanks. That worked a charm.
Excellent!
