Hi Leandra,

  I ran into a similar problem with OS X 10.5 last year. The fix was
obscure enough that I wrote myself a note to remind what the solution was.
I copy it below and hope it helps.

Regards,

There was a problem running the mindstorms software on OS X 10.5 that
claimed a file was broken while starting up.


I found the solution on a German website (translated by Google). The 3
steps they gave that seemed to fix the problem were:


1.) Download and install the MAC Leopard fix patch from lego (click
"Patches" on the left):


http://mindstorms.lego.com/en-us/support/files/Advanced.aspx


2.) Download and install the Fantom Driver from the lego site (Click
"Drivers" on the left)


3.) Make a symbolic link called fantom.framework that points to
Fantom.framework in /Library/Frameworks:


sudo ln -s Fantom.framework fantom.framework



It seems this may be an issue with the case-sensitivity of the underlying
file system. Mac OS X usesa case IN-sensitive file system by default. This
was hidden from users by a layer that maintained the case of filenames
separately. I chose to enable case sensitivity (which is not the default)
in the underlying filesystem when last installing OS X so that
Fantom.framework and fantom.framework no longer point to the same point on
the disk. Step 3 side steps the issue.


I can't help but notice that there is also a VISA.framework directory there
which looks like a LabView thing. It may well be that one does not need the
Fantom driver at all and simply needs a similar link or renaming of
VISA.framework to something like visa.framework.
