I think what you mean is "and still no new Macs". There is plenty of evidence that Apple is investing in Macs; get out of the MacRumors negative vortex for a reality check.
If Apple were to spin off their Mac division it would be one of (if not THE) most profitable computer companies in the world. It is still big business. My suspicion is Apple has been burned by the hot mess that the Intel chip business has become as they are having a hard time predicting what processor they should be tooling their new Macs for. Waiting for Sky Lake, but Sky Lake turns out to be a mess. Then waiting for Kaby Lake, but Kaby Lake is late and potentially challenged with the same problems that have essentially broken Sky Lake. Sure takes me back to the IBM / Motorola G-series days and the whole reason Apple went Intel. Now Apple is being hosed by chip makers again. It is no wonder they are exploring the idea of making their own chips.
Go on.
What's wrong with Skylake?
