Hi all, My friend just got a new hard drive as the old one was dying and put Leopard on it (macbook), she tried to update to 10.5.1 straight away as 5.0 is so bad but when she downloaded it and it went to restart/instal the software it crashed on "configuring installation". After about two hours she finally gave in and restarted the computer and as she did she noticed it flick to the folder icon with the question mark (can't find and operating system i think???) for a few seconds before loading up into 10.5.0. She tried again and the same crash happened. She asked me should she reinstall the operating system or would it be okay just to go back to a time machine backup. (only got one... just before the crash). Anyone heard of a similar problem or have any advice for her?
