I have a imac desktop I bought in September. it comes with Ilife 09
My sister just got an macbook. it comes with ilife 09..but includes a ilife 11 cd disc.

We upgraded her ilife from 09 to 11.
Disc never asked for like cd key or anything.

Can I use it on my imac and upgrade 09 to 11? And will apple find out and shut down my computer??
