yamaha tyros 2 environment file

I'm kind of lost. Was trying Logic 8 pro on my friend's mac pro and there's no environment file for Yamaha Tyros 2. I've been considering Logic Pro for purchase but found out that external midi environment will not suit my needs.
Is there any place I can find that environment file?
Looks like the Apple doesn't stand behind it's product. There's no contacts or email addresses to ask for a support help.

Thanks
