They got smart and started calling m rest mass. This way it is a useful tool (an invariant to coordinate transformations and invariants are 'Jewels' in relativity) while leaving energy to be called energy.
r = 2M not r = M. Whether you use mrelativistic or mo the answers should be the same and hopefully right. Your answers are wrong.
