I agree I sounds very hard to believe but according to reports in 2001 former Apple CEO Steve Jobs approached Sony with a prototype Vaio (Sony laptop) running OS X. Jobs apparently admired the Vaio range of laptops and despite shutting down the Mac clone service years before he was willing to “make an exception”.
The source of information comes from none other than ex-Sony president Kunitake Ando. Sadly Ando turned down the proposition as VAIO sales were taking off in the international market, meaning Sony didn’t have the resources to work on an OS X version of the computer.
This is certainly a very interesting piece of information and I would love to see how it would’ve turned out and if the Mac lineup would be the success it is today.
