Hi, I've just been doing some housekeeping on my iMac (August 2007 2.4GHz Alum), clearing out old apps and getting rid of unwanted login items etc. I was expecting bootup time to be better but I am getting a 42 sec delay between pressing the power button and seeing the Apple logo. I just get a white screen and no disk activity for the 42 secs. I don't remember seeing this before but I don't reboot that often to be honest... After the Apple logo appears the system then seems to boot up as normal and is at the login screen in a further 28 seconds. What could be causing this? Could it be because I installed a new Seagate Barracuda internal hard drive? Surely it doesn't take 42 sec to spin up??? Is it worth doing a PRAM reset? Any other ideas what could be causing this? Thanks, Craig.
