Apple seems to be doing very well with its own processors. But a recently published academic paper reveals that Apple was, at one point, attempting to port its operating system to work with ARM processors.
In fact, a former Apple intern, Tristan Schaap, who now serves as a Core OS engineer at the company, has explained how he was working on a project to get Mac OS X Snow Leopard working on ARM devices, reports Apple Insider.
The secret project became less clandestine when it was published by the Netherland's Delft University of Technology. Apparently Schaap wrote up a Bachelor thesis on his 12 week Apple internship in 2010, but the research has been embargoed. How did he get on? Apparently during the course of the project, he managed to get devices "booting into a multi-user prompt," though some issues still remained due to a "poor implementation on the debug hardware."
What are the chances of this being real and relevant? Well, we know that Apple sometimes tests its engineers out on fake projects to make sure it can trust them, so it could be a pure dummy project. Or, equally likely, Apple was keen to understand more about the ARM architecture.
Either way, given Apple's current dominance in the phone and tablet sector, I suspect a shift to ARM is unlikely. [Apple Insider]
