Hi,

Could you please advise and guide me on the possibility of installing OS X Mavericks(10.9) or Mountain Lion (10.8) on the latest 2015 macbook pro retina pre installed with yosemite (10.10.x)?

i come to understand that macbook pro performance is much better with mountain lion and mavericks and hence would like to know about the ability to downgrade to such an OS.

proper assistance would be really great help.

look forward to hearing soon. thanks in advance
