The four-paragraph note from Cook, obtained by Ars Technica, aims to address any concerns that employees might have about the transition. "I want you to be confident that Apple is not going to change," the new CEO wrote.
He said that the company built by the leaving chief executive, Steve Jobs, has a "culture that is unlike any in the world." He promised that Apple will "stay true to that," because it's in the company's DNA.
"I am confident our best years lie ahead of us and that together we will continue to make Apple the magical place that it is," Cook wrote.
The new CEO has been with Apple and worked with Jobs for over 13 years. He is widely regarded as an operational genius who may lack the charisma and vision of Jobs, but many believe can keep the company headed in the right direction.
Analysts on Wall Street also have few concerns about Apple in the short-term with Cook at the helm. They view the transition as a change years in the making, with Apple's deep bench of executives groomed for a new era without Jobs as CEO.
