I have been reading with interest the various threads on the older models of ScanSnap and the issues with dropped support for scanner software. I have been getting round it on my old S510M by using VueScan.
On a whim I downloaded the latest driver for the ix500 and to my surprise it connected to my S510M and it works . And this is on Mojave.
However back in the day my old software had a function ‘Scan to DTPro’
I don’t see it now, was it dropped or have I missed a step?
