The 2019 Mac Pro’s main purpose was to provide much needed reassurance that Apple cared about the Mac. In prior years the quality of the Macs had fallen over all product lines. And the question of does Apple care about the Mac at all was a legitimate one.

This Mac Pro was about resetting and giving a clear signal that Apple was willing to invest in the Mac far more than it was about ‘slots’.

Today, Mac hardware is the best it has ever been, and no one is reasonably questioning apple’s commitment to a Mac hardware.

So it makes sense for the Mac Pro to make a graceful exit.
