Who were macbeth KING OF SCOTLANDS allies during his reign?

Medieval kings rarely had any permanent allies, they might ally with another king one year and go to war against that same king the next. His closest ally was of course his wife Queen Gruoch who was the ruler of Moray, a noble in her own right and not just a Queen consort. He was also the occasional ally of Thorfinn Sigurdson, the Earl of Orkney with whom he also went to war against on at least one occasion. He was also friendly toward Harald III king of Norway, or at least managed to avoid conflict with him. He was also reputedly friendly with the Normans and the Irish kingdoms, though there is little recorded details of this in the historical records. His relations with England were hostile throughout his reign.
