He comments on the rapidly increasing awareness of VueScan through macOS Catalina:

While most Mac users complain about the Catalina update, the managing director of Hamrick Software is happy - for his company and for the users. Massive increase in VueScan downloads through macOS Catalina By reconstructing scanner drivers, VueScan even supports old models that manufacturers no longer waste time on. There are new updates every one to two weeks. The software makes it possible that over 6000 scanner models work with the latest macOS. This means that drivers that were originally only available in 32-bit can be used by VueScan in 64-bit environments. Technically, however, there is a difference, because while SilverFast installs the drivers supplied by the manufacturers, the VueScan team takes the trouble to reconstruct the drivers from the manufacturers - including those from old scanner models. Īt first I thought VueScan is a software similar to SilverFast that has built-in drivers for all kinds of scanners. VueScan enables the setting of file name specifications, output formats such as PDF and takes a lot of work off the scan process thanks to the automatic specifications. VueScan naturally runs with 64-bit and is therefore fully compatible with macOS Catalina.

If you use your scanner with VueScan instead, you are no longer dependent on the unreliable repairs from the manufacturers and can continue to operate your scanner without problems - even if Apple suddenly no longer supports 32-bit apps, as is the case with macOS Catalina the case is.
