Pro Tools LE 7.5 on OS X 10.8.5

Hi.



I just bought on ebay Mbox2 Mini with PT LE 7.5. It's still shipping, and I now learned that it won't run on my MacBook Pro 10.8.5.

What do I have to do to get it working? Download drivers? Upgrade to 8?



My purchase was conditioned by the low price, therefore I would like to find a cheap solution for this.



Thanks in advance for the help.
