Apple's real software design genius, Bertrand Serlet, leaves

The bloke credited with developing Apple’s MacOS has announced that he is leaving Jobs’ Mob to spend more time with scientific projects.

While many Apple fanboys think that Steve Jobs comes up with everything at the fruit-themed cargo cult, in actual fact Bertrand Serlet was the brains behind the Mac OS X.

He is to the operating system what Jony Ive is to the hardware design, and his exit should send ripples through the maker of shiny toys.

Serlet’s work on Mac OS X, which originally released March 24, 2001, has played a crucial role in driving the success of Apple’s Macs and mobile products.

In a statement Serlet said that he had an incredible time working for Jobs, but he is fed up with making products and want to concentrate on computer science.

Serlet was one of those who came back to Apple with Jobs in 1996 from NeXT.

It was not all plain sailing for Serlet. When Mac OS X debuted in 2001, it was the chocolate teapot of operating systems. It had a somewhat rocky start. Not only were many features missing, and there were some compatibility problems with external hardware.

After ten years cooking, he fixed a lot of the OS X’s problems with only a few hiccups, such as the release of the spotty “Leopard” . His crowning glory was the release of a cut down version of the iOS in 2007. The micro version of the OS shoved under the bonnet of a smartphone has done rather well and inspired several clones.

Until his exit, Serlet was working on the next version of the Mac OS X, dubbed Mac OS X Lion, which is due out later this year.

Apple’s more high profile talent lately has been considering its future with the company now that Jobs is off sick. Even Ives was rumoured to be leaving, although he was provided a pair of golden handcuffs to keep him in place.
