Apple has grown the size of its global developer community by 250 per cent (two-and-a-half-times) over the past two years.

The increased interest in Apple is due to the switch to the Unix-based OS X operating system, and its entry into the open source community, according to The Australian.

Apple's worldwide head of developer relations Ron Okamoto said: "The BSD-Unix base of OSX has also made it attractive to Linux developers and good compatibility with Java is also attracting interest."

Okamoto added: "Enterprise developers are reporting an increase in customer interest in Mac. Unix is where a lot of these guys are coming from."

According to Okamoto Apple is "not necessarily" competing with Linux for users switching from traditional BSD Unix. He told The Australian: "Linux gives people another motivation to examine their platform choice."
