Hi all, Got a macbook running 10.4.11 and got hold of an image of Leopard from work, so burnt it on a dual DVD and put it in my mac. Want to wipe it and upgrade to 10.4.11 to 10.5. The DVD boots when in Tiger and then I click on install, and it restarts and I'm greeted with a pale blue screen with an apple logo and a spinning white and blue round symbol. like this: I've left it an hour and a half then gave up and rebooted it into Tiger to come on here and ask. Is it a duff DVD? It comes up at the Tiger screen okay with all the options. Am I being too impatient? Is an hour and a half too short? What's the next step? How can I get leopard on this without spending a shed load of money? Thanks for any replies!
