DESCRIPTION
LeopardAssist is a simple tool to install Leopard on older, unsupported Power Macs.

It bypasses the 867mhz processor check in Leopard install to allow systems that don't meet the requirements to complete installation.

No modified Leopard DVD's, no hardware hacks or tweaks, just a one-time run application. (Much like XPostFacto)

Version 2.0 overhauls the codebase at the request of testers worldwide. It attempts to improve support across all systems, including ones previously known unsupported or problematic. This version also attempts sports a completely rewritten user interface.

WHAT'S NEW
Version 2.0:
  • Eliminated Boot File, data is written directly to PRAM
  • Major Bug Fixes
  • New User Interface
  • Tested on second generation PowerPCs (eMac G4)
REQUIREMENTS
Mac OS X 10.3.9 or later (10.4.11 is recommended).

    MBRICE  I picked up an eMac G4 and decided to do a bit of extra work on LeopardAssist. Did away with boot.txt as requested by beta testers, now writing the 867mhz script directly into the Parameter RAM. This should correct problems on many systems which previously had issues finding boot.txt on restart (a majority of cases).  (Version 2.0)

    JUSTINGRAZIANO  A great app. Works excellent, it would be nice if there was an option to mod the OS X install DVD so that it doesn't have to be installed everytime you reinstall OS X but it's still nice.  (Version 1.2)

    MBRICE  Leopard sure won't speed on these older machines, although some of them have been upgraded, particularly those with aftermarket graphics cards which will allow Leopard's video acceleration.

    Cheers to everyone who showed support, I really do wish I could have continued working on this but unfortunately my G4, my only testing machine had a logic board failure which severely damaged the progress of the project.  (Version 1.2)

    BRIAN KENDIG  Running Leopard on an unsupported machine still means it'll be a lot slower than Tiger because Leopard dropped support for the video acceleration in unsupported Macs, right? For example, if you put Leopard on a Sawtooth G4, the graphics will be painfully slow?  (Version 1.2)
