[QUOTE="Inuevo, post: 1823112, member: 235824"] Thanks, that's encouraging and sounds like the easiest option to start with. I have considered cloning but I'm wondering if the method I've read about is considered the best: 1 – clone the Mac drive to an external drive, 2 – then update the Mac's OS to, say, El Capitan. 3 – test legacy apps and if they don't work wipe the Mac drive and restore the cloned backup to it. Have I understood that correctly? It seems to me that a less risky approach which not would involve wiping the Mac drive would be to: 1 – clone the Mac drive to an external drive, 2 – then update the clone to El Capitan. 3 – Boot into that, and if the apps don't work abandon it and go back to the untouched Mac drive. Is that not a better way of doing it, or am I missing something? [/QUOTE]
