If I buy a mac with OS X 10.6.5, and then I upgrade it to OS X 10.6.6, how can I downgrade it back to OS X 10.6.5? I don't mind having to reinstall the entire operating system if necessary.
Could this same method also be used if I upgrade to OS X Lion (OS X 10.7)?
The reason I'm asking is because I heard that OS X 10.6.6 removed support for installing boot camp using a Vista CD, and that's all I have. Thus, if I ever want to wipe my computer and reinstall everything, I want to be able to still use a Vista CD to install boot camp.
