A while back, there was a big controversy when Fujitsu updated their software to be 64-bit clean and stopped supporting older ScanSnap models.
Eventually, Fujitsu relented and added support for the older units. Thank you very much.
Now, they’ve done it again. The latest ScanSnap software no longer supports my perfectly functional scanner. But the last version that does support the unit seems to function just fine on the latest macOS.
So, just keep using the old version, right? Sure, except that Fujitsu’s auto-update mechanism is a royal pain in the ass. Every few days, it will tell me that a new version is available. Additionally, the user interface for declining the update is (intentionally?) deceptive with a double-negative, making it easy to accidentally apply the update and screw myself.
Worse yet, the update notification not only steals focus, it prevents the computer from shutting down until you answer its inhumane prompts!
The solution to this annoyance is to turn off the ScanSnap’s auto-update function(s). This is accomplished using a separate app that you might not have noticed among all the detritus that Fujitsu installs. See the screenshot below for all the details.
