MacOS/Rhapsody and "MacTel" clarification (from:http://www.maccentral.com/news/0297/feb14.shtml) The Digital Guy
After chatting with various sources in an attempt to avoid making things even muddier, I'm going to explain why there's so much confusion surrounding the "NeXT" Mac OS, and why Rhapsody isn't going to run on Intel chips...but the Mac OS is.
That first paragraph pretty much illustrates why there's so much confusion. You see, "Rhapsody" isn't just Mac OS "8" (or whatever it winds up being called), it's the new OS consisting of the OpenStep API's with a new, advanced Mac interface running on top of the Mach microkernal (referred to as the "yellow" box) AND a component to insure backward compatibility with system 7.x applications (the "blue" box). Thus the code name "Rhapsody" actually refers to the bundling of two seperate technologies, and not just the new Mac OS.
As confirmed by Avadis Tevanian and Jim Gable, (see ), the yellow box WILL run on intel chips. Essentially, poor souls who made the mistake of buying a Pentium based system will be able to run the SAME OS as a PowerPC Macintosh. The only difference is that the blue box won't be there, so they won't be able to run 7.x Mac applications. The decision makes sense when you realize that making 7.x apps run on Intel would be a major engineering effort for a group of people unlikely to have an older software investment to protect. Intel users WILL be able to run Mac applications ported to the new OS and recompiled to run on the Intel based Mac OS.
Another way of looking at it from the Intel NeXT OS side of things is that they're going to upgrade their NeXT OS. Their existing investment in OpenStep programming and applications is preserved.
To sum up:
* The Mac OS WILL run on Intel chips. * Applications written for the new Mac OS will run on Intel based systems with a simple recompile. * 7.x applications won't run on the Mac OS for Intel chips. * 7.x applications WILL run under the new Mac OS for Power PC chips, code named Rhapsody.
