Hi Peter, No I haven’t started it up in Safe Mode. What should I do start it in 
safe mode and keep it in that mode for how long to see if the problem occurs in 
safe mode? Should I operate the same apps as I was using before when the iMac 
froze or is it sufficient just to start up in Safe Mode and then close down and 
go back to normal?

Thanks

Matt.
