Steve Jobs might seem like a well-mannered man, but back in 2000 when Microsoft purchased Bungie for $30M, Steve Jobs came out of his shell and yelled at Ballmer, according to develop-online.
Back when Bungie created the Halo series and became a huge game developer, it used to create games on the Mac. Once Apple found out about Microsoft purchasing Bungie, Steve Jobs apparently called up Steve Ballmer and yelled at him over the deal.
"As soon as we announced we bought Bungie, Steve Jobs called," Fries said.
"He was mad at [Microsoft CEO Steve] Ballmer and phoned him up and was angry because we'd just bought the premier Mac game developer and made them an Xbox developer."
Later that day Fries got an email from Ballmer, asking him to call Jobs and calm him down. Eventually, Microsoft settled the dispute with Apple and said they would port some games from the PC to the Mac, to help remedy the lost developer, Bungie.
Since Bungie has left developing for the Mac, they have only since ported one game over, Halo: Combat Evolved back in 2005, the first of the very popular series. The Halo series has since become a staple in Microsoft's Xbox 360 sales, breaking records for first day releases across the globe.
