It seems Apple changed their Open Firmware spec so frequently, it's difficult to tell what systems LeopardAssist will run on just by looking at the machine model or revision number. We can't test every system out there since it would cost thousands in hardware costs, but the public have been a great help and have allowed us to start building our hardware compatibility list. Before you read the list, ensure you know what all the terms mean.
have been tested and are known to work with LeopardAssist.
are either unsupported by LeopardAssist at this time or are locked off by other requirements other than the 867mhz check. You may still test these systems and report back on any successes.
have yet to be tested and may or may not work.
Any machines not listed on here support Mac OS X Leopard natively, exception being the G3 series which does not work at all due to lack of the AltiVec Instruction Set. G5s are not included as they are already supported. Running LeopardAssist on any of these later systems will still allow access to the optimization features (1.1 onward).
