Apple Computer Inc and Symantec Corp have extended their collaboration on Symantec’s Bedrock technology for facilitating development of applications that will run under both Windows and Macintosh System, and they will work together to develop and market the next-generation development environment for the Macintosh: the environment will initially target Apple’s PowerPC-based systems, and will address the needs of developers creating native applications; they will share engineering resources and build on Symantec’s new C++ 6.0 for Macintosh, and on Apple’s Macintosh Programmer’s Workshop; it will be based on an open architecture that enables interoperability with software tools developed by other vendors.
