i bought macbook it was loaded with 10.6.4...
and as usual i used my friend's original dvd 10.6.3 that came with another macbook 2009 to install a clean copy
i entered the dvd after bootting i get a massege says
.Mac os X can't be installed on this computer"
if you want to restore you system from a time machine backup click restore from back up"
i usually boot from cd by holding "C"
now when i hold "Alt" it gives me screen with "lock!" centered and password needed
i am so disappointed
any help will be very appreciated
best wishes.............
