Q: How uninstall El Capitan and replace with Snow Leopard clone?
I've had terrible luck running El Capitan, particularly in conjunction with CS5. It takes (literally) 10x longer to save a .tiff file in El Capitan than it did in Snow Leopard. I suspect far too many processes running in the background, most of which are probably not needed, but I don't know that for sure. Something is wrong.
I have a perfect clone of my old Snow Leopard installation and am wondering if that can just be installed right over El Capitan, like when one does any update of the OS, or do I need to erase the entire partition first and then install the clone?
(I know, I'll then have browser problems, but...)
FTR: Mac Pro (early 2009, 2.66 Ghz, single quad-core), currently running OS 10.11.5
Thanks very much,
Mac Pro, OS X El Capitan (10.11.3)

What I'm really wondering is if I could use the Snow Leopard CD to install Snow Leopard right over El Capitan without first erasing the drive, thereby leaving my apps intact. I hope that makes sense? If you see what I'm wanting to do?
Thanks for your follow up, CFS88. It is not actually possible to reinstall Snow Leopard over El Capitan. In this situation, you will need to first erase the drive before you'll be able to install an earlier version of OS X.
Have a great rest of your day!
