In June of 2012, Apple announced that Mansfield, who joined the company in 1998, was planning to retire from his position as senior VP of hardware engineering. The company said that he would be replaced by Dan Riccio, Apple's vice president of iPad hardware engineering.
Times change, and in this case, quickly, as that decision was soon rescinded, with Mansfield becoming an adviser to CEO Tim Cook for "future products." Later still -- about two months so -- Apple changed his role once again, putting making him Senior VP of Technologies.
However, when Riccio was named as Mansfield's replacement, several senior members on Mansfield's team voiced concern that Riccio was not prepared for the job.
Reports say that Mansfield's decision was at least in part fostered by the ouster of former iOS software head Scott Forstall, but also because of the pay package that Cook offered him: cash and stock worth around $2 million a month.
A leaked company-wide memo emailed by Apple CEO Tim Cook and sent last October noted that Mansfield would be staying on with Apple for another two years.
Apple spokesman Steve Downling reaffirmed the change, saying,
Bob is no longer going to be on Apple’s executive team, but will remain at Apple working on special projects reporting to [CEO] Tim [Cook].
