Shredder 12 Mac

Help please!

I'm considering buying Shredder 12 Mac.

The product website talks about a "Huge Book" openings database that comes with Shredder 12 that is about 1GB in size. Does anyone know if this is downloadable when you buy the program, or just accessible online?

It's not clear on the product website whether the program comes with any openings database(s), or just ones you can access online?

I'd really like to have it/them on my MacBook hard drive, as I'm not always online.

Any info regarding quality/depth of Shredder 12's accompanying opening databases also greatly appreciated. 

Hey Hello, I use shredder 12 and its really a good and fresh engine on my macbook. Regarding the book I have not found a way of downloading it but I think the built in books are ok.

Thank you :)
