Disable system-wide ctrl-click as right-click in Mavericks

There is no system supported method for disabling ctrl+click from functioning as a secondary click in Mavericks.

You can use Karabiner Elements to remap "Control+LeftClick to LeftClick," which essentially disables this behavior system-wide.

Step 1:

Install Karabiner Elements: https://karabiner-elements.pqrs.org/

Step 2:

When you then go to open Karabiner Elements, it will have a couple security issues you need to resolve.

The first will be to allow the installation of a kernel extension:

The second will be to allow input monitoring:

Step 3:

Once those security issues are handled, you then need to add a complex modification. Visit: https://ke-complex-modifications.pqrs.org/#control_lclick_to_lclick

Then click Import on the Disable Ctrl Click modification:

This will add the complex modification to Karabiner Elements and enable the functionality:

Addendum:

However, I don't know of any web apps (and certainly not most or many) which don't recognize and respect Command+LeftClick as a way to multi-select. That is the standard for macOS.

In my VMWare Windows 7 guest, I have found (after reading this post) that using Ctrl+Command+LeftClick works the same as Ctrl+LeftClick would in a hardware Windows machine.
