My ADS-1500W desktop scanner ( a fabulous device) stopped working today after a number of Big Sur updates. Must use image capture, Brother Iscan doesn't support it anymore. Scanner is fine as I ran it with Windows machine and it is perfect. I have all my records on the Mac so it is a huge pain to scan to a windows machine and send them to my Mac. I get it that technology improvement can advance the cause, but this is a bummer. Any suggestions on a solution will be welcome. Also brings up Must be an administrator upon launch.
