The figures emerged in a survey conducted by Apple among developers at WWDC. The results also show that 29 per cent of developers plan to release Mac OS X software within three months. Three quarters of developers will release Mac OS X-compatible products within the next year.
Apple found that a "large percentage" of professional Mac-developers are programming in the Java and Objective C programming languages. Both of these are supported by Apple's Cocoa programming environment, which has been developed as a tool to build applications native to Mac OS X.
The survey hints that a significant number of Mac OS X-native applications will be released over the next year, with 35 per cent of developers using Cocoa to build their products.
