ScanSnap Users Should Delay Sierra Upgrades

by Adam C. Engst

Fujitsu (a TidBITS sponsor) is warning users of the company’s ScanSnap document scanners and accompanying software to avoid upgrading to macOS 10.12 Sierra at this point. Fujitsu has identified a variety of problems [1] associated with its ScanSnap software when running in Sierra. They include:

These problems affect documents created with all ScanSnap scanners including the ScanSnap Evernote Edition.

Fujitsu does not provide an estimated date for an update that will provide Sierra compatibility, but we’ll be sure to mention it when it appears. Until then, we recommend that anyone who relies on a ScanSnap scanner delay upgrading. The problems are not guaranteed — one ScanSnap user on TidBITS Talk reported no issues with scans he made with Sierra’s public beta — but because they can also apply to previously scanned documents, they merit serious caution.

If you use a ScanSnap scanner and have already upgraded to Sierra, Fujitsu recommends opening files only with ScanSnap Organizer Preview. And, if you do use other apps to open PDFs, be sure to avoid saving any changes.

After the initial publication of this article, David Hamrick, developer of VueScan [2], told me that VueScan is compatible with Sierra and supports ScanSnap scanners with its independent drivers. As such, VueScan doesn’t suffer from the problems facing the ScanSnap software, although using VueScan won’t address issues with previously scanned documents.
