Ugh.
On updating iTunes and Quicktime my mac froze and upon rebooting I discovered that something went wrong.
Very wrong in fact, with the “Welcome to Leopard” wizard appearing on logon and refusing to let me log in.
One full time machine restore later and my mac is working again, unfortunately it’s now refusing to back up.
But now I’m looking to replace my mac with something home grown again… 
replace your mac it just cant be done you just need a mac with more oooompph perhaps a midrange iMac
