Espon scanners disappeared and reinstallation not working after Mac 0S 10.13.6 Update
Apple seems to have done something with its update for Mac OS 10.13.6 to disable my scanner software or its re-installation. I found in an online search that some Canon users have had similar issues with 10.13.6 and scanners so it looks likely to be a Mac update issue.
I have two Epson scanners:
ES-H7200
and
GT-F730
admittedly not the latest but Epson has drivers all the way up to Catalina for these models so they are not obselete.
After updating my Mac OS 10.13 to version 10.13.6 now the scanners will not work.
The drivers have disappeared. When I download the drivers software from Epson and reinstall the Scanners are not listed in my Printers and Scanners section of System Preferences.
I have restarted the computer, disconnected and restarted the scanners in various ways.
Nothing works. I have two perfectly operable scanners and I would like to use them again.
Any suggestions would be gratefully received.
