I recently tried to boot my daughter's Late 2008 13" MacBook from a clone of the boot volume on my Mid 2010 15" MacBook Pro and failed.

My guess is that I failed because my installation is rooted in my install disc and can't boot a Mac of a different configuration any more than my disc could.

And that got me thinking that if the d/l's we get from the App Store are configured for our individual Macs (as I've read), then there's no such thing as a "retail", i.e. universal, version of OS X any more...that an installer burnt to a thumb drive is useless on Macs that aren't of the same configuration as the one that did the original d/l.

Am I correct?

Thanks.
