TiVo announced TiVo Desktop for the Mac with support for Tiger on Wednesday. TiVo Desktop lets you play music from your iTunes library and view images from your iPhoto library on your television through a networked TiVo series 2. Although the updated version adds support for Mac OS X 10.4, it still does not support TiVoToGo. TiVO representatives have confirmed that TiVoToGo support is planned for the Mac.
TiVo Desktop is free, and available for download at the TiVo Web site. It is not compatible with Intel-based Macs.
