EDIT 2: Sorry, realised@ace already reported this a few months ago further up this thread. Oh well, you get the warning twice, I guess.
PSA…
Old thread I know, but be aware that the ScanSnap Manager app is being unsupported from Nov. 2024 (downloadable until Oct.2024), making Sonoma or Sonoma+1 (whatever macOS 15 is called) likely the last macOS it works with:
I personally use the ScanSnap Home app now anyway which is not as bad IMO as others feel it is. But I know other users on these forums use ScanSnap machines using the Manager app instead who may want to avail themselves of this info.
