Hey guys, Seriously need you help! If someone can come out with a plan, I will love them forever especially as its valentines day <3 Basically here is what I want! My Music Studio at home is running 10.6.8 (Snow Leopard) Runs amazing, so much better than this new stuff and my MacBook Pro is minimum 10.7 as its late 2011. Basically I have tried to Carbon Clone Copy my Mac Pro (Studio Mac) to the internal HD on my MacBook Pro 2011. It won't let me boot as apparently you can not downgrade to earlier than you purchased but I know there is a way round this as I can boot 10.6.8 from an external drive just not an internal one. All I want is two identical systems running so when I am working around and about studios on my laptop I can bring it back into my main home studio on my Mac Pro and just continue the work flow without any pains! If anyone knows any way around this, like deleting certain files or whatever please just let me know! James PS really want to use the carbon copy instead of having to install fresh!
