MacOS – Snow Leopard OS X Partition (El Capitan)

I have a couple things I'm trying to do that I can't find a solution for.

The end goal is to be able to run DVD Studio Pro 4 on my Mac which has El Capitan installed. The software is pretty old but I need it for a client so I'm trying to figure out a way to get Snow Leopard installed on a partition that I set up on my drive. The only real reason I need Snow Leopard (10.6) is because it's the last version of OS X that runs 'Rosetta' which is required to run PowerPC application (which DVD Studio Pro is).

I set up a partition, plugged in my Apple USB SuperDrive (I have a Mid 2014 Macbook Pro so I no longer have a disc drive), put the Mac OS X 10.6 installer in, rebooted the computer and tried to boot it from disc by holding 'C'. It recognizes the command then opens up the old Apple start screen so I know it even recognizes the disc in the drive since it's clearly pulling up an old OS X start screen. The issue is that it never gets past that initial screen. I'm not sure if I need to wait it out longer but I've let it run for 10 minutes with no result.

I then tried to boot holding 'Option' but my SuperDrive didn't show up as one of the options.

I then went into the contents of the disc itself because technically I can install Rosetta because it's part of the 'Optional Installs' for that operating system and if I can just run Rosetta it will solve my problems. Of course when I try to proceed the Mac gives me a pretty strongly worded warning that I probably shouldn't do it because this old software is not compatible with the current OS installed on my computer (the whole reason I was trying to create a partition anyway).

To clarify, I can't just run the installer off the disk for the OS because the application is actually a PowerPC application and has the 'no' symbol on top of the application so I can't run the installer directly.

My main questions are:
– Is there a way to just install the OS on the partition without doing the reboot? And if so, will it work running a PowerPC installer on my Intel Mac.

• Is it ok for me to install Rosetta directly on my El Capitan system? (I know the answer is likely 'no' but just thought I'd ask in case…)

• Is there another boot approach I could try to get past that first screen?

Thanks for your help!
