How do I go back to the OS before Yosimite?

Hi Guy's


Is there a reliable process to follow to go back to the pre-Yosimite (Mavericks?) OS.


I'm an Aperture user and own MBP15 (16GB) and MBA11 both running Yosimite.


I'm sick and tired of the poor performance of Yosimite. My MBP15 took so long to open Mail this morning I gave up and switched to my windows machine.


I thought about upgrading to El Capitan having read about it's supposed performance improvements. Having checked out these forums it seems that there are still problems with El Capitan and Apples photographic apps so I'm not prepared to risk the potential problems.


It seems the best option to me at the moment is to go back to the pre-Yosimite OS.


Any help or advice would be appreciated.
