Log[2, $MachineEpsilon] evaluates to -52. and RootApproximant[$MachineEpsilon] === 2^-52 evaluates to True

In the past $MachineEpsilon in Windows-based and OS-X-based systems differed because the Windows-based systems used Intel processors and Apple used Motorola/IBM processors. Apple changed over to Intel in 2006. So now it would be hard to find a system running Mathematica that doesn't give 2.220446049250313`*^-16 for $MachineEpsilon because that is the value retuned by any system running an Intel Core i3, i5, or i7 processor(s).
