Apple Rhapsody Developer Release 1

Apple Rhapsody Developer Release 1 is the first Developer Release of the Apple Rhapsody operating system, released to developers on September 1997. This build is the first available Mac OS build to be based on the NeXTSTEP codebase following Apple's acquisition of NeXT to create a transitional operating system between the classic Mac OS system and a then-upcoming new generation of Mac OS operating systems that would later be known as Mac OS X.

Overall, this build is relatively similar to OPENSTEP 4.2 in terms of functionality. However, many portions of the user interface has received updates to reflect upon the classic Mac OS interface of the time.

This developer release is available in both i386 and PPC versions. The i386 version lacks the Blue Box environment, while the PPC version includes it with a copy of Mac OS 8.1 inside of the virtual machine.
