Iomega has Carbonized its IomegaWare drivers and tools making them compatible with Mac OS X (as well as Mac OS 8.6 and higher).
IomegaWare 3.5 not only adds support for Mac OS X 10.1 and above, it also adds support for Active Disk enabled titles and makes some minor changes to the Classic Mac tools. IomegaWare helps users find, format, protect, manage and change settings on Iomega drives. Support is included for Zip, Jaz and PocketZip products, including the new FotoShow Digital Image Center, HipZip, and the Zip FireWire adapter.
The 3.5 update is free. You can download it (a 7.8MB file) from the Iomega Web site.
