Hi all,
I'm brand new to macs - Had my new 20" imac only 18 days (I love it - it's such a joy to use generally) but it keeps hanging, not restarting, not shutting down when I ask it etc. It seem to be itunes related. Sometimes after I have used Itunes I get the problem, sometimes it wont start up at all. When I open the force quit window its usually itunes thats 'not responding' but when I try to force quit it - it doesn't make any difference!!! I wait and try it again and makes no difference.
I must have hard reset my imac around 20 times - which I don't like doing.
I have updated to the latest OS X 10.5.6. I unistalled itunes as recommended from my local apple stores advise and downloaded from apple itunes site and it's no different.
I have just ran the disk utilities repair permissions after reading above and it states a few things have been modified and can't be repaired

should I worry??? and after making the window bigger to read the lines now that has frozen and given me the rainbow wheel.
I have opened Force quit window and that says Disk utility is not repsonding as I type aarrgghhhh. Pressed force quit - which it seems to have closed thankfully - it has given me the send report to apple window - yes, and it just sits there!!! I have seen about 6 of these and only 2 of them have actually sent and closed themselves down - this is just hanging there!!!! So after only 10 mins since my last hard reset I guess I will have to do it again now
what is going on, what am I doing wrong??? can anyone help me please??
UPDATE; I think I may have found my problem after reading another
thread on here - I think my problem was my ext harddrive used for time machine causing the problem.
