Fair enough … but be careful what you ask for.
There is new software available, but it works only on specific models. And there are onerous registration/licensing restrictions that (in my opinion) have no place in hardware of this type, marketed in this manner.
Details are posted above (post #26) so they won’t be repeated here except to mention the additional restriction described by another MPU forum member @tomalmy in this MPU thread:

Apparently the new software is even more restricted when obtained for a previously-purchased scanner such as the iX500.
Think about that. If you recently bought an iX500 scanner, still currently marketed by Fujitsu, and “upgraded” to the new software … you are stuck using your expensive scanner on just your one current computer.
Fujitsu is displaying a stunning disregard for its customers. Not acceptable.
What if you want to get a new computer? Or simply “nuke and pave” the macOS software? Or replace the disk drive? Or use the scanner on another computer in your home - maybe on a MacBook laptop in the TV room temporarily while you watch TV?
