mac air mid 2011 (bought in april 2012) does not support mirroring
I bought a mac air (at eaton center in Toronto) last april. It says that it is a mid 2011 model. On the preference>display there is no mirroring option. Does this mean that the laptop I bought less than a year ago is already obsolete? Any suggestion would be really welcome. Thanks
