The main thing that’s stopped me from upgrading to Catalina on my iMac is the lack of 64-bit driver support for my sturdy old ScanSnap 500M.
Official support for the scanner ended long ago, but I haven’t given up hope. Every few years I’ve been scouring the Fujitsu website for new software, and occasionally I’ve been able to download software for more recent ScanSnaps and install it successfully.
For the last year or so I’ve been running version 6—but last night an alert popped up on my iMac screen (running Mojave) saying something like “ScanSnap V7 is now available. It includes support for some older scanners.”
That last cryptic remark sparked my interest. I clicked the Update link and was taken here. No mention of the S500M.
I didn’t let that stop me. I clicked the link for the oldest scanner on the list, which I think was the S1500M. Download and installation went perfectly, and the scanner still works—the software looks exactly the same as it did before.
Then, the real test: I installed the same software on my MacBook Pro with Catalina installed. Success! My ScanSnap now works in Catalina (if you check in the System information app, all of the ScanSnap software is now 64-bit).
In both installations I had to fib and tell the installer that my machine was newer than it actually is—but that’s always been the case when I install relatively recent Fujitsu drivers.
Give it a try!
