Common forms of 'superglue' are cyanoacrylates, best used for non-porous materials to make a tenacious bond, which has, however, low shear resistance.

Cyanoacrylates were commonly used in the 1990s to attach "security devices" to computers etc. As Equill notes, the bond has poor shear resistance. If somebody has glued a security eye to your Mac or printer case, insert a screwdriver through the eye and twist clockwise until you feel resistance. Twist a bit harder and then relax. Repeat anti-clockwise. And iterate. Eventually, the glued-on fixing will fall off without damage to the case.
