2021 USB-2 HS-Series Control Boxes with Mac OS 10.14 or later only:

This new 64-bit ViewFinder version 9.10 replaces the previous version 7.4.4 from 2009. If you are working with newer Mac computers and using Mojave (10.14), Catalina (10.15), Big Sur (11.0) and beyond, you should purchase and use this new software to avoid operational problems. NOTE: Upgrade 9.10 has also been working on High Sierra (10.13).

DO NOT USE WITH SCSI CONTROL BOXES — We have found connectivity problems with systems using SCSI boxes and the Raytoc FR1SX SCSI to FireWire Converters. This problem will hopefully be fixed in a future update.

This version is compatible with Intel Macs and Apple Silicon Macs running OS 10.14 or higher. This version was primarily created to correct changes to Apple operating systems beginning with MOJAVE (10.14) and beyond. Functionality remains the same as ViewFinder 7.4.4 and may still have some lingering bugs due to limited beta testing and the fact that we are trying to accommodate all of the changes that Apple has made on several past OS versions.

Not recommended for Macintosh users that remain on older computers and are using Mac OS of High Sierra 10.13 or earlier...you should continue to use ViewFinder 7.4.4. Previous versions of ViewFinder software for Mac and Windows machines are on the Better Light website:  http://betterlight.com/downloads.html
