Hi, I haven't done enough testing to say for sure.

I know that my BIAB ver 12 Pro for Mac never locked up.
It worked great. I'm keeping it safe in case
BIAB 2009 doesn't work out!

My brand new BIAB 2009 for Mac, Everything Pak,
was received on an External Hard Drive, installed
to run from the Mac, but leaving the Real Drums
and Real Tracks on the external drive.

The problem is when I play around with RealDrums,
every song locks up, it will play nicely, but then no buttons work, the song
keeps playing, and the only way to stop it
is to quit BIAB.

My first Theory is that once I eject the External Hard
Drive (and take away any possible use of
RealDrums and RealTracks), that BIAB 2009
will run fine, i.e. that all the locking up
on every song, where the buttons don't
respond and the song keeps playing,
comes from problems using the external hard drive.

I'll probably copy the RealDrums and Real Tracks
to my hard drive, and test further, but I actually liked
the idea of having them external.

How would I know if I need to use the additional
power cord for the external drive? I'm not using
it so far.

Thanks!
