                                                          A Letter from Steve Jobs
August 24, 2011
To the Apple Board of Directors and the Apple Community,
I have always said if there ever came a day when I could no longer meet my duties and expectations as
Apple's CEO, I would be the first to let you know. Unfortunately, that day has come.
So I resign (辞职)as CEO of Apple. I would like to serve, if the Board feels fit, as Chairman of the
Board, director and Apple employee.
As far as my successor goes, I strongly suggest that we name Tim Cook as CEO of Apple.
I believe Apple's brightest days are ahead of it. And I look forward to watching and contributing to its
success in a new role.
I have made some of the best friends of my life at Apple, and I thank you all for the many years of being
able to work alongside you.

Steve
