SilverFast software has been upgraded to add Mac OS X Leopard compatibility for numerous Nikon film scanners. Version 6.6, first released May 25, bails out Mac owners who were told by Nikon that the company will not provide Nikon software support for Mac OX X 10.5. The updated scanner software will support owners of older Nikon film scanners (Coolscan IV and V ED, Super Coolscan 2000, 4000 ED and 5000 ED) and the most recent revision (6.6.0r1a) adds medium-format capable LS-8000 and LS-9000, on both PPC- and Intel-based Macs running OS X 10.5 and above. The software is available for a range of prices (between $400 and $512 for the Super Coolscan 5000 for example) and requires a minimum of Mac OS X 10.3.

The software also offers advanced features such as dust and scratch removal, (including on Kodachrome slides, which, due to their unique formulation, are normally an exception to the dust and scratch removal features of many film scanners).

Silverfast also has a multi-exposure option to increase the dynamic range of a scan by using multiple passes on one image. The software offers IT8 color calibration and works with hundreds of flatbed and film scanners in addition to Nikon's scanners.
