In “” (20 September 2016), we warned users of Fujitsu’s ScanSnap scanners to avoid upgrading to macOS 10.12 Sierra, based on the company’s dire predictions of potential data loss. Happily, it turns out that Fujitsu was just playing it safe until its engineers were able to pin down the exact conflicts, and they turn out to be far more minor than previously predicted.
In its updated notice, Fujitsu (a TidBITS sponsor) now outlines when running in Sierra:
Do not use ScanSnap Organizer, ScanSnap Merge Pages, or CardMinder.
Do not use Excellent mode when scanning A3 (11.7-inch by 16.5-inch) documents. Fujitsu explicitly says that no image data will be lost nor any blank pages produced when scanned content is saved in Letter (8.5-inch by 11-inch), Legal (8.5-inch by 14-inch), A4 (8.3-inch by 11.7-inch), or smaller sizes.
Do not use the following functions in either Quick Menu or the application: Scan to Print, Scan to Evernote (Document), Scan to Evernote (Note), Scan to Google Drive, or Photos.
For those looking for more information, Fujitsu has produced, complete with the operation in question, the color mode, the paper size, the image quality setting, and workarounds.
Practically speaking, if you use a ScanSnap scanner, you should verify that your scanning workflow doesn’t rely on an affected aspect of the ScanSnap software or A3 scans in Excellent mode. If not, you can safely upgrade to Sierra.
