Adding the MCR directory to the system path: (see readme.txt for more information) **If you are using Mac OS 10.3 or higher, your shell is most likely the bash shell** To add the MCR directory to the system path, add the following lines to your .bashrc file, replacing with the directory in which the MCR is installed: export DYLD_LIBRARY_PATH=/v710/runtime/maci:/v710/sys/os/maci:/v710/bin/maci:/System/Library/Frameworks/JavaVM.framework/JavaVM:/System/Library/Frameworks/JavaVM.framework/Libraries export XAPPLRESDIR=/v710/X11/app-defaults Instructions: 1. Open a Terminal window (located in /Applications/Utilities) 2. At the command prompt in the Terminal window, type: cd /etc to navigate to the folder named "etc" located in your home directory. 3. Open the .bashrc file for editing (using pico or the editor of your choice): pico bashrc 4. Add the specified lines to the end of the file, save changes and exit
