I have submitted a ticket for this problem, since it is really annoying that I can only use the scanner via USB connection, which is the only solution that works out of the two provided by Fujitsu. The other workaround was to connect the scanner to the WiFi using the ScanSnap Wireless setup tool, which in fact does connect the scanner to the WiFi, but still doesn’t solve the issue that the ScanSnap Evernote application fails to detect that my computer is connected to a wireless network; hence, keep getting the message “to enable wi-fi scanning, connect your computer to a wireless network”. It seems like Evernote completely forgot they have this product, it is frustrating that scanners that cost half the price of this expensive unit have been updated to work with the latest Mac OS update.
