My first iFixit experience

My Problem

I had some problems with my session on Mavericks so i wanted to come back to OS X Mountain Lion without erasing my HD and have a new HD hybrid!

My Fix

The repair was really easy!!! The problem was the installation of the OS X on my new HD! It didn't work on the first time with network connection and reboot program so I had to make an image of OS X on my old HD.

My Advice

Be careful to do an image of OS X before changing your HD! It will be easier for you ton install the OS on the new HD!
