Over the next two years, a major effort was applied to porting the original Macintosh API to Unix libraries known as Carbon. Mac OS applications could be ported to Carbon without the need for a complete re-write, making them operate as native applications on the new operating system. Meanwhile, applications written using the older toolkits would be supported using the "Classic" Mac OS 9 environment. Support for C, C++, Objective-C, Java, and Python were added, furthering developer comfort with the new platform.
