According to Ed Fries, the former VP of Game Publishing at Microsoft, Jobs was furious to lose the developer who was working on Halo for Mac and PC. The Apple CEO had hosted a public preview of Halo at Macworld just months before.
Fries was responsible for brokering a deal with Apple back in 2000 to make the peace.
"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 wed just bought the premier Mac game developer and made them an Xbox developer."
"So, during the day, I got an email from Steve Ballmer asking me to phone Steve Jobs and calm him down about the whole thing," he said.
"Anyway, we did this deal with Apple where wed port some PC games to the Macintosh and help Peter Tamte create this company to do it, and I had to go to a Mac developer conference and get on stage and talk about this whole new partnership. It was a pretty strange time."
