SLOW SHUT DOWN TIME FOR MOUNTAIN LION

I've opened a new discussion because the last one wasn't titled properly. Here's the link to it:

Hello, I was hoping somoene could help me with the following problems.

I have brand new Macbook Pro Retina, 15inch, 16G RAM, 500G of SSD, running Mountain Lion, and lots of professional recording software. My macbook frequently shuts down after 30 seconds, that wonderful grey wheel spinning in the center of the screen as if it were an old PC.

I've contacted apple frequently. They check to see that I've repaired disk permission, they reset...the RAM i believe, they ask if i shut down all the programs. Even through doing all of this, usually my macbook takes 30 seconds to shut down. Sometimes it takes only 5, which is how it usually should be. ANd this occurence seems to be inconsistent with the apps I use. Sometimes it takes long to shutdown when i've barely used a thing. Other times it shuts down immediately when i've used a lot of different programs at once. So there's no constant.

The apple boys suggest reformatting the computer to make sure it isn't a hardware issue. I refuse to accept that after only 3 months of use I already have to reformat everything. It's not the most enjoyable experience because I'd have to reinstal all my audio software despite Time Machine's magic tricks. Any suggestions?
