Ive got a 2007 MacBook Pro running the Latest Version of Snow Leopard, with no problems. It originally came with OS X 10.4 (Tiger I Think it was called). I still have the original OS X 10.4 Installation disks. I would like to install and play some early Mac games which no longer play with OS X 10.6, Snow Leopard. For example, the original Myst, which, I understand will play on OS X 10.4. My question: Can I install OS X 10.4 on my MacBook Pro without overwriting or interfering with OS X 10.6, so that I can play some of these older Mac games. In other words, can I have both operating systems installed at the same time and choose which one to boot up and use. Thanks.
