I have had continual problems with my Macbook pro (which I think stemmed from installation issues) and was advised to archive and install Mac OS X. I have tried to do this and it won't work!!! The disk checks for consistency okay but once the installation commences it fails. The first time I tried the log said something like idle for 10 mins 1 connection open then idle for 20 etc etc up to 50 mins before I had to shut it down with the power button. I have now tried it a second time and the log just says "Extracting". Help please!!
