Hi everyone I successfully installed retail snow leopard + 10.6.8 combo update, using iBoot+retail DVD method described here. everything is working fine and nicely immediately, without needing any fix. But now I'd like to install some more recent version of OSx. I'm a bit confused by the various guides I found, none of them starts with 10.6.8, since the AppStore won't let me download Sierra or previous OSx. The configuration I'm using is the one listed in my profile.
