I downloaded a Leopard to run on my computer (Kalyway). Ive tried to install different versions on my computer before on a seperate hard drive but never even gets to installing. I wont go into details because its hard to explain. But anyway, this is the last time I'm going to try. I think I need to inject an Nvidia kext into the ISO so that it works. I may need other kexts. In the readme I got it says tht I need to put the kext into the folder and double click this .command file that is included but when I double click it says it cant open the file and needs to know which program to use. So any ideas? Ive had a quick look on the the main websites but its a little too messy and complicated to find anything.
