  The MACE (Major Atmospheric Cherenkov Experiment) is a 21 m diameter
gamma-ray telescope which is presently being installed at Hanle in Ladakh,
India (32^0 46^' 46^" N, 78^0 58^' 35^" E) at an altitude of 4270 m a.s.l. Once
operational, it will become the highest altitude very high energy (VHE)
gamma-ray telescope in the world based on Imaging Atmospheric Cherenkov
Technique (IACT). In the present work, we discuss the sensitivity estimate of
the MACE telescope by using a substantially large Monte Carlo simulation
database at 5^0 zenith angle. The sensitivity of MACE telescope is estimated by
carrying out the gamma-hadron segregation using the Random Forest method. It is
estimated that the MACE telescope will have an analysis energy threshold of 38
GeV for image intensities above 50 photoelectrons. The integral sensitivity for
point like sources with Crab Nebula-like spectrum above 38 GeV is ~2.7% of Crab
Nebula flux at 5 sigma statistical significance level in 50 hrs of observation.
