Mac OS Update Assistant screen appeared with a message 'An error occurred preparing the software update'
I clicked on OK
New screen appeared - 'Choose start up disk'
' Target Disk Mode '
' Are you sure you want to restart this computer?'
I clicked yes and I can't do anything on my Mac. The installation screen appears all the time.
