So i have a PB G4 15 inch and just replaced the HDD. I know i had Picasa on my old HDD and now it's saying i can't install because i don't have an intel based mac. All older versions say the same. I bought my mac 3 years ago from a private seller, is there any way they put a program to "trick" and make it seem as if i have an intel mac? same with flash player.. FRUSTRATED!
