In classical Latin the 'c' sounds is always pronounced as a 'k' sound, so the Romans would have pronounced it as 'Mack-edoinia'. Due to linguistic drift Latin-derived languages have softened the hard 'c' sound into more of an 's'. English, though not a Latin based language, also borrowed this convention.

So in truth both are correct.
