Why is there an installation problem with Vex libraries on Mac (using MATLAB R2015a)?

2 views (last 30 days)
We are receiving the following error when installing the VEX libraries on a Mac. Below are the error messages that we received during the installation of the VEX Cortex Support Package.
We anyway went ahead and opened it after install fail and the software appears to work correctly and we are able to make a Simulink model. However, when we try to deploy, it compiles but fails when it tries to download the program to the controller.
Warning: An error was encountered while installing the VEXNet Serial USB

From the System information, it appears like you are on a Mac 10.10.2 OS version. Unfortunately, the VEX USB driver for Mac in the VEX Support Package for R2015a and R2015b will not be installed automatically on this Mac OS.
The workaround is to install the VEX Driver manually on a Mac running 10.10 OS (Yosemite). To do so, follow these steps:
1) Install MATLAB and Simulink
2) Install the VEX Support Package
3) Obtain the VEX Driver file from here: https://app.box.com/s/v76iqkyv1dmml61unj32
4) Install the Driver
5) Restart Mac and relaunch MATLAB
MathWorks will update the Support Package installation in a future release to remove this limitation. Apologies for the inconvenience.

Katie, do you recall the name and directory of the file? It could help others with the same problem.

I suggest trying this:
Go to the terminal window (Applications -> Utilities -> Terminal) and command
sudo installer -package '/Volumes/VexCortexCDC_1.1/Installer_10.5/VexCortexCDC 1.0.0.pkg' -target /
and authenticate when asked.
I do not promise this will work.
