Is Lego Mindstorms NXT 2.0 software compatible with Mountain Lion? 

 

My son saved money for a long time and finally last week had enought to buy NXT.

I'd like to upgrade my Lion to Mountain Lion but since this NXT is the most important thing in house at the moment I don't want to ruin the experience with uncompatible OS.


OS X Mountain Lion

    I upgraded to Mountain Lion and can't connect with Bluetooth anymore. Mindstorms runs but crashes when I try to connect to my NXT device. I haven't tried anything else yet.

    Hi,

     

    I have Mountain Lion and my Lego mindstorm software doesn't work. It crashes at each launch. I have to reinstall the software each time i want it to work. Then at the second launch it crashes.

     

    I think it has something to do with the flash version installed on my mac. But i'm not sure.

    I have also upgraded to Mountain Lion and am having problems with the Mindstorms NXT version 2 software crashing.

     

    All the following actions cause a crash.

     

    1 Editing a existing program.

    2 Dropping a object into a new program.

    3 Trying to connect to the NXT.

     

    I expect there are more but i will be digging out my old windows laptop and using that.

    Supposedly works with Mountain Lion, has some issues in Lion.

    I have looked at deggie's link and the workaround described is the method i used to get Mindstorms NXT to work with Snow Leopard. I skipped the Lion upgrade so i cannot say that it will or won't work with Lion. Even with a complete reinstall it will start in Mountain Lion and then crash as soon as you try to program or connect with the NXT.

    Answering to my own question:

     

    I installed Mountain Lion and have Mindstorms app running well.

     

    Here's what I did:

    - Removed Flash player software (I had newest version installed). Newset Flash player versions seem to break Mindstorms installation and it crashes right after opening it.

    - Installed Mindstorms, checked the Flash player version number

    - Downloaded older version of Flash player (same as Mindstorms installs), can't remember where

    - Installed that older version of Flash player. This had to be done because Mindstorms' Flash player installation did not install browser plugins.

    - Don't update Flash player

     

    I have not tried bluetooth connection, usb works fine.

     

    I wish Lego would fix this Flash player -problem. Fix files at mindstorms site don't work.

    Did you use the installer from:

     

    http://en-us.kb.lego.com/ics/support/KBAnswer.asp?questionID=2655              

     

    This installer does not seem to have an issue with the latest version of flash installed. However, I am unable to get it to work with blue-tooth under Mountain Lion.

     

    It worked fine with Lion and the latest version of flash.

     

    When you download the .iso file, it will have an .exe extension. Removing the .exe allows you to open the .iso and continue the install.

    Looks like the link doesn't work. Try this:

    And then click the following:

                   MINDSTORMS NXT #8547

                        2. How can I obtain a replacement for the LEGO MINDSTORMS NXT 2.0 software for set 8547?

    Yep the link http://service.lego.com/en-us/helptopics/ works.

     

    After uninstalling Mindstorms NXT and reinstalling, with the downloaded image, i still have a program that crashes every time i try to use it.

     

    This is the only program that i have had problems with since upgrading to Mountain Lion.

    I just got the NXT 2 after I had changed to ML 10.8.1.

     

    - I first installed Mindstorms with the iso image I got from the Lego support page.

    - It uninstalls Flash and installs its own one.

    - I installed the latest Flash version, basically undid the Mindstorms Flash installation.

     

    => Mindstorms works great with the UBS cable.

    => With Bluetooth it crashes every time.

     

    I also bought an external BT dongle, which only works with my Paralells 7 with the WinXP VM for Mindstorms, but not with the Mac host. I had to activate the BT adapter with the Bluetooth Explorer.

    I emailed Mindstorms tech support last night, and got this response this morning:

    Thank you for contacting the LEGO Mindstorms Technical Support line.

     

    Yes, LEGO NXT 2.0 is compatible with Mac OS X 10.8 Mountain Lion but we have found one issue with the BT stacks on Mountain Lion whcih is not compatible with LEGO NXT software. Our developers are currently working on a solution to solve this problem.

    They also suggest downloading and installing the latest NXT 2.0 ISO from here.

     

    Hopefully, it won't take their developers too long to come up with a fix.

    I was able to get the NXT brick drivers 1.1.3 working following instructions here: http://huestones.co.uk/node/166

    Brick is detected via USB, no luck with Bluetooth though.

    Note: Once Brick is detected on OSX it can also be enabled on a virtual machine running Windows (I used VirtualBox for the virtual machine)

    Thanks to huestones instructions i now have Mindstorms NXT working, including all imported blocks. (I only needed to install the NI-VISA drivers).

    I spoke at length with someone at Lego Mindstorms support. Unfortunately I didn't think to get his name.

     

    He indicated that its a known crash with the NXT software and Mountain Lion bluetooth. However, he was unable to give me any encouragement regarding when it would get fixed. In particular, he indicated there is also a known issue communicating using broadcom bluetooth chipset which is used in Macs for the last several years. He said the NXT software has been broken talking to broadcom devices since 2007. Five years and no fix.

     

    He indicated the software is a version of Labview written by National Instruments.

     

    I've checked my systems. My 2012 Macbook Air and 2011 Mini use broadcom chips, while my 2007 white macbook has "cambridge silicon radio". I am able to communicate using my 2007 white macbook running snow leopard.

     

    Overall I can't say I'm happy with Lego's response. It essentially sounds like their software has been broken for years and they haven't bothered to fix it. I'm personally in a bind since the system we had envisioned using for first lego league isn't practical to use without bluetooth. I realize bluetooth can't be used in competition.

     

    It doesn't seem the Lego supports their NXT software well nor the Mac platform.
