downgrading osx leopard over osx lion
Hello, just bought a used MacBook pro (2006 model) , it came with lion installed. Problem is I have over $2000 worth of software that I need for work and I quickly discovered the problem with lion and powerPC apps. Anyway I have my original leopard install disk so figured I'd just downgrade as I know it's compatible with the macbook it's self. I was going to keep lion for future use but when I boot from my leopard CD and try to install I get a "cannot install 10.5.5 on this mac" ...now I'm assuming that there is just a compatibility issue with lion and leopard, but I wanted to make sure that was what is going on here or if I may have another issue I need to address before I proceed. If it is safe to just do a clean restore I'm fine with that!
Thanks in advance for any help!
