I'm not going to go on a diatribe about all the bugs I'm having with Mountain Lion - just suffice it so say I have them and I'm getting a little tired of it. I'm now at the point that I want to move back to Lion or Snow Leopard. "Moving back" itself isn't a big deal, but Mail appears problematic. When I made the commitment to ML I started using it's Mail exclusively so it's not on any of my other systems. Does anyone know if there's a way to easily export the mail files in a manner that can load directly into Lion or SL without having to export, import, then manually delete the redundant files? Thanks in advance.
