I have a working copy of Photoshop CS3 on a 2011 MacBook Pro. I would like to put it and an older OS on a bootable partition so I can use the CS3 occasionally and not have to pay monthly fees to Adobe. I am getting a new Mac soon, probably a MacBook Pro, and will want to use the partition with it since the CS3 will not run with newer systems.
I have the DVD's for CS3 and an install DVD for OS 10.5 from the 2011 machine. How do I make sure it is bootable and this system works? Can I use Time Machine to move the CS3 from the 2011 machine or should I use the install disk? Since the OS disk came with a specific laptop, will it work with a new machine as a bootable partition?
