We derive the master equations for gravito-electromagnetic perturbations and numerically solve for the Quasinormal Mode (QNM) spectrum and the ringdown waveforms. Our research results show that increasing the MOG parameter $\\alpha$ leads to a decrease in both the real and imaginary parts of the QNM frequencies for electromagnetic and gravitational modes.
