Apple chief executive Tim Cook offered to give Steve Jobs part of his liver while the company's co-founder lay dying in bed waiting for a transplant, according to a new book.
Becoming Steve Jobs, by Brent Schlender and Rick Tetzeli, claims that Jobs angrily turned down Cook's offer, despite his rare blood type making the chances of a liver match very slim.
According to the book, which charts Jobs' life from young entrepreneur to founding and running the largest company in the world, Cook went to see Jobs at his home in 2009, something he would do every day.
Jobs had been ill since late-2003 and had now reportedly developed ascites - an accumulation of fluid in the abdomen. He looked frail and tired, and would lay in bed all day while waiting for a liver transplant.
Cook was convinced Jobs was going to die and went to a hospital for tests to see if he shared his friend's rare blood type.
