Hi, I'm running 10.7.4 right now and would like to get the new Mountain Lion. However I have a little problem. I need to run some software (Earobics) that unfortunately is only compatible through 10.6.x, if you can imagine. I read in some other threads people mentioning partitions. Is there some way for me to make this work, where I can go back to 10.6.4 (I still have the disks) AND get the new ML? Would I then be able to bounce back and forth somehow, so I could run the Earobics software in the 10.6.4 and run everything else in ML? I use separate user accounts on my imac. Is that how I'd get between the two OS?? Just explain it in really plain english, as it's all new to me.
