MacOS Catalina compatibilty with scanner

You should be able to use that scanner with Catalina using the Image Capture app on the Mac. See: https://epson.com/Support/Scanners/Perfection-Series/Epson-Perfection-4180-Photo/s/SPT_B11B170011?review-filter=macOS+10.15.x

When you download it, it should go to your normal Downloads folder and have the name "ESICA_587.dmg"

(I just did that to verify)

Then use the following instructions from the same link:

1. Double-click to create a disk image on your desktop.
2. Open the disk image.
3. Double-click the installer icon to begin the installation.

For those of you who are concerned with Epson Scan 2 not working in Catalina - I have an ET-2650 EcoTank. Before upgrading to Catalina I kept reading and seeing warnings that the Epson Scan software wasn't Catalina compatible. After I upgraded to Catalina though everything worked great. Simply upgrade to the latest software version BEFORE installing Catalina.
