iDeneb has recently been updated to v1.3. This new version includes the latest Mac OS X 10.5.5 update as well as a few fixes and driver updates.

iDeneb is a Mac OSX Leopard release modified by Layne and iHackintosh Team, to run on non-Apple computers. This universal release can run on both Intel and AMD based machines. The current version, iDeneb v1.3 10.5.5, has EFI support, though it cannot boot on older machines due the lack of Non-EFI boot. However, this drawback has been worked out with the Chameleon bootloader which can be installed on SSE2 computers.

iDeneb v1.3 can be found throughout the usual channels. Support and further information about this release can be found at the official iDeneb site.
