NuKernel is amicrokernel that was developed atApple Computer during the early 1990s. It was the basis for theCoplandoperating system. It was written from scratch and designed using concepts from theMach 3.0 microkernel, with extensive additions for softreal-time scheduling to improve multimedia performance. Only one NuKernel version was released, with a Coplandalpha release. Development ended in 1996 with the cancellation of Copland.

The External Reference Specification (ERS) for NuKernel is contained in its entirety in its patent.[1]

The one-time technical lead for NuKernel,Jeff Robbin, was one of the leaders ofiTunes and theiPod.

Apple's NuKernel is not the microkernel inBeOS, nukernel.
