Chosen Solution
System: Macbook pro 13" Mid 2012 2.9GHz i7. Graphics: Intel HD graphics 4000 opening Launchpad is too slow but over all machine runs fine when I use lightroom/photoshop. Booting time also increased - O/S is on SSD and all apps are installed on SSD. Occasionally system freezes. Need to hard boot. Took it to genius bar and they suggested that most probably motherboard is gone and they said it costs around $450 Is there any way it can be quick fixed without changing mother board and if need, is this something doable. Also, is it really worth it? Genius bar guy is telling to live with it and instead spend money on new laptop… System is modified almost 3yrs back to SSD and HDD (removed optical drive) Last year upgraded SSD to 1TB.
Did the Genius Bar tell you about the Hard drive/IR cable program. They were replacing all the cables on the 2012 13" for free.
