Phew....thanks all for your input. My Mindstorm NXT 2.1 is now working on iMac desktop and MacPro laptop, both running on a OS X 10.6.8.

Here's what I did:

1. Downloaded the update for NXT 2.1

http://www.legoeducation.us/eng/Support/NXTSoftwareUpdates.cfm?paID=5645

2. Downloaded the "Fantom Driver"

http://us.mindstorms.lego.com/en-us/support/files/default.aspx#Driver

3. Restarted the computer, and opened up the application/NXT 2.1. It works! Yeah! Well, that's all I did though :) Tomorrow I'll have more time programming the robot with my son. I'll let you know if I run into any more glitches or a need to download other files (as suggested with a few other posts on several forums and listserves).

Thanks all for your help.

I had the same problem, when I updated to Mac OSX lion. I called LEGO and they were very helpful. I currently am running Mountain Lion and no problem. I have Lego NXT 2.1f5.

I can try to email you the zip file if you need it.

I haven’t coached a team for a couple years so have not updated my software since v2.0 came out. I tried to run v2.0 on my MacBook Pro (3 years old running Lion) this summer and it kept crashing. I just ordered the v2.1 software but haven’t received/installed it yet. As soon as I get it I’ll test it out.

LEGO Education has been VERY supportive in the past so I recommend giving them a call. If you discover a global issue/solution, please post it to the list.

Have you gone to Lego Education and downloaded the update?

Hello All!  I need advice...

I have a Mac desk top and Mac Pro laptop, both operating on Mac OS X 10.6.8

After loading the NXT Software v2.1 on both computers, the program is NOT

opening up.  It reads:  Error code 1003/A required file is broken

Has anyone had a similar issue?  Is it because the software is not compatible

with Mac OS X 10.6.8?

Any suggestions in fixing this issue?

Thanks a bunch!
