MacTCP was not supported on PCI-based Macs, but older systems could switch between MacTCP and Open Transport using a Control Panel called Network Software Selector. It was included with System 7.5.2, a release for the new PCI based Power Macs, and became available for older hardware later. Open Transport was introduced in May 1995 with the Power Mac 9500. Using STREAMS also appeared to offer a way to "one up" Microsoft, whose own TCP/IP networking system, Winsock, was based on the apparently soon-to-be-obsolete sockets.

It also presented two practical advantages to the company STREAMS' multiprotocol support would allow them to support both TCP/IP and AppleTalk from a single interface, and a portable cross-platform version of STREAMS was available for purchase commercially, one that included a high-quality TCP implementation. This change in the market led Apple to move to support STREAMS as well. At the time it appeared STREAMS would become the de facto standard. STREAMS had a number of advantages over sockets, including the ability to support multiple networking stacks at the same time, the ability to plug in modules into the middle of existing stacks to provide simple mechanisms for filtering and similar duties, while offering a single application programming interface to the user programs. System V included an entirely new networking stack, STREAMS, replacing the existing Berkeley sockets system. Through the late 1980s several major efforts to re-combine the many Unix derivatives into a single system were underway, and the most significant among these was the AT&T-led System V.

MacTCP was also lacking in features, however, and a major upgrade was clearly needed if Apple was to keep its hand in the Internet market. MacTCP and the previous generation AppleTalk library were slow on PowerPC-based Macintoshes because they were written for previous generation 680x0-based Macintoshes and therefore ran under emulation on PowerPC-based machines. MacTCP emulated the Berkeley sockets system, widely used among Unix-like operating systems. Among the other protocol stacks supported, MacTCP was becoming increasingly important as the Internet boom started to gain momentum. The only one that was widely used throughout the OS was the AppleTalk system. Prior to the release of Open Transport, the classic Mac OS used a variety of stand-alone INITs to provide networking functionality.

Apple also added its own implementation of AppleTalk to the stack to support legacy networks. Based on code licensed from Mentat's Portable Streams product, Open Transport was built to provide the classic Mac OS with a modern TCP/IP implementation, replacing MacTCP. to its implementation of the Unix-originated System V STREAMS networking stack.
