I have had a new iMac 21 with i3 and 500gb hard drive for 3 months, but recently had a few minor problems.
I did an Onyx scan which told me that the disk was in need of repair, so I had backed-up all my files and data and applications to an external hard drive just in case.
I then used the Migration Assistant just to do a double check but gave up on it when it spent aeons trying to calculate the size of my music, film and photo files to transfer!
Then - without doing anything, although I intended to do a clean install with the original supplied OSX and Apps. disks - the machine switched to a small window asking for my password - which it then refused to accept - even though I know it was correct etc
I have left it switched off for about 5 days and tried again this morning with the same result.
Anyone got any ideas what is wrong - and how I can successfully re-install OSX from the disk ??
As I bought a new iMac27 with i5 a month later, I may have mistakenly inserted that Install disk which is a later version being 2011 instead of the iMac 21's 2010 version - so when I held down key C I am allowed to start the installation process, but then get a message saying -'It is not possible to upgrade this version of OSX .'
