Is this for leopard or snow leopard? I know this is irrelevant and this forum is specifically for lattitude laptops but has this kext been optimized for just the amd model cpus that are common in lattitudes or any amd cpu? I'm asking because I have an amd 550 phenom2 and after installing this kext it says it fails to load it and my sync errors still persist. Thanks for any help or info.
