The rumors are once again being brought to the surface by a French site MacBidouille regarding Apple working on the ARM processor based Macs. A reliable source has claimed that Apple has in possession a couple of prototypes of several ARM-based machines such as an iMac, Mac mini, and 13" Notebook with 4-8 64-bit ARM Quad-core processors. It is being said that these machines have gone too far in the development process and they all comes with a new keyboard that makes use of a large-format Magic Trackpad. We are suspecting that Apple is nearly ready to make the announcement but still isn’t feeling so confident about it as yet.
MacBidouille isn’t a site which we would generally associate with rumors and this leads us to doubt the reliability of the sources it has stated. But this is not the first time we’re hearing about the ARM machines; these rumors have been there since years. The prototypes had always been there along the years but maybe the company wasn’t so sure about the plan and this explains the doubts of moving ahead with the project.
We suspect that this idea might have first occurred to Apple when it threatened to abandon Intel's chips if they didn't work to slash power consumption. Apple could have easily gone for AMD processors but rumors of the ARM already started appearing.
