Is there anything (like iOS) that emulate force touch for older MacBook? In iOS, there are tweaks (available through Cydia) that enables force touch features (such as menus) on older iPhones by touching and holding an item to emulate force touch.

Are there any available on OS X ?

If that matters, I own a late-2013 MacBook Pro
If the sensor isn't there in the hardware, there is no way to enable the function. 

It's the equivalent of trying to tun an old CRT television into a touch screen
[though that has actually been done, but not without some very expensive extra hardware]
