Hi there, I've got a small issue with my 12" powerbook. I have 10.3.9 installed on it, but recently managed to get a hold of Tiger to upgrade it. Once restarting and choosing my language the installation said 'tiger cannot be installed on this system'. I googled about to see what could be the issue and found nothing on why this wouldn't work. I have a DVD Drive, I have a firewire port, I even have 10.3.9 - which i assume should be the right firmware to upgrade from. Is there any reason why it would be doing this? Cheers!
