If you own an Epson All-In-One Printer or a stand-alone Epson Scanner, you probably use the Epson ScanSmart application for your scanning. If you recently updated to macOS 27.2 you probably have discovered that you now get an error message that says the computer cannot communicate with the scanner.
With Epson’s recent release of a complete software package for macOS 27 (Golden Gate), many people have tried installing the latest version of the software expecting the new version to correct the issue. Unfortunately, it does not.
We actually experienced this issue with all of our Epson units, and after spending hours working with both Apple and Epson support teams, we finally have a resolution.
As it turns out, while Epson did release an updated software package for macOS 27, which eliminated the dreaded messages about lack of Intel compatibility, it turns out that the scanner drivers in those packages are incompatible with the 27.2 update.
Epson has actually released an updated driver which fixes the issue, but for some reason, has not seen fit to include it in the full macOS 27 package (as of this writing).
If you find that your ScanSmart application is no longer working, here are the steps to fix the issue.
First, go to; Finder / Applications / Epson Software / Uninstaller.
The Uninstaller app will present a list of all of the Epson software on your Mac. Check the box next to the ScanSmart app and click Uninstall.
When you get the message that the uninstall was successful, close all open windows and restart your Mac.
Open a web browser and go to www.epson.com/support. On that page, enter the model number of your Epson device. If you have more than one Epson device, just choose one as the new ScanSmart application works for all of them.
Once you are on the product page, look for the drop-down box that says “Please choose your OS”. Here you should select macOS 27.x (Golden Gate), and press the “Go” button.
When the page refreshes, scroll down to the section labeled “Utilities”, and click the “+” sign.
Scroll down to find the Epson ScanSmart v3.7.9 file and click the Download button.
This will download a .dmg file. When you open that file, a new window will open with the new ScanSmart installer. Run the installer until it completes.
Once you have completed this new installation, your scanner(s) should once again be working as before.
