About reinstalling OS X
I have an older (2010) 13 inch MacBook Pro running El Capitan.
Is it possible to COMPLETELY ERASE the hard drive and install a fresh copy of an OLDER OS X version? I want to install either Leopard or Snow Leopard, which would have run on the machine originally. I envision needing to start up from the install DVD. Seems like I used to do this. Is it possible? Any information or wisdom as to how to accomplish this is welcome. Thanks in advance.
