I am using 10.9 and would like to install 10.7 on an external volume. I have the “Install Mac OS X Lion” application, but when I run it, I get the message
This version of Mac OS X is too new to run “Install Mac OS X” from Mac OS X 10.7.
Well, I do not want to downgrade, I just want to have a way to boot into 10.7. Is there any way around this?
