Apple Computer has seeded within the company a new
build of its Rhapsody next-generation
operating system that uses a new microkernel.
Sources inside the company said Apple replaced the
Mach 2.5.8 microkernel that was used as the
base for NextStep and OpenStep. Instead, Apple
developers have opted to make the Mach 3.0
microkernel, which comes from the MkLinux
development effort, the new heart of Rhapsody.
One source, who asked not to be named, said he was
concerned that Rhapsody on the Mac 3.0
kernel was likely to be slower and have
"potentially more bugs."
Other sources, however, claimed that the developers
were familiar with the Mach 3.0 technology
since Next already had started porting OpenStep to
Mach 3.0 prior to being purchased by Apple
The sources added that changing the kernel and
making minor adjustments to the YellowBox, the
part of the operating system that contains Java
support and the OpenStep APIs, is easier than
using the previous version of the Mach microkernel.
Rhapsody is due out next summer
... at least you can drive something fast, arm your-
self with powerful tools, and look good doing it.
