Workaround

Note: If you cannot launch MATLAB at all, please see Bug Report 1116607, "Cannot launch MATLAB 14a or earlier on OS X 10.10 Yosemite".

For MATLAB R2011a through R2014a only.

To install this patch, you need the name and password of an account with Administrator privileges.

Download the appropriate patch file for the version of MATLAB you wish to patch. Look for the file in your Downloads folder, the Desktop, or wherever your Web browser saves downloaded files. If your Web browser did not unzip the patch file for you, double-click the file in the Finder to unzip it. Double-click the .dmg file to mount the disk image. At the top level of the mounted disk image is an application such as R2014a_patch_1098655.app. Double-click to launch it. Select your MATLAB installation. Select the root folder of the install, for example, MATLAB_R2014a.app. Enter the name and password of an account with Administrator privileges. New Java class files will be installed in the java/patch/com/mathworks/widgets folder of your MATLAB installation. When the upgrade is complete, you can launch MATLAB. Fix

This bug was fixed as of R2014b(8.4).
