I have a Mac Pro (mid 2012) that came pre-installed with Lion. I have since upgraded to El Capitan and am starting to have a lot of problems with Adobe CS6 running properly, so would like to downgrade back to the original factory installed OS. If I run the recovery software will Lion be reinstalled or will El Capitan be installed? If the latter, is there any way of getting Lion back? (I don't have Time Machine.)
