Macar (or Macareus) was the son of Aeolus. He committed incest with his sister Canace and subsequently killed himself. Another Macar was one of Odysseus' seamen. The name, a more or less stock epithet for a god, means 'happy', 'blessed' (macar).

In the case of Aeolus' son, the propitiousness of the name clearly proved quite ineffective! (In modern times, the same name, with the same meaning, became well known as that of Archbishop Makarios, the Cypriot head of state who died in 1977. This was of course his religious name, his real or lay name being Mikhail Khristodolou Mouskos.)
