The first Mac Pro orders have started shipping, according to reports across Twitter. It seems that for now only off-the-shelf configurations are shipping, while built-to-order machines will ship early next month.

The Texas-built computer now lists shipping and delivery dates going into February on Apple’s web store, indicating that either the demand for these machines is higher than expected (an unlikely situation, given the price tag), or the supply is having a hard time keeping up with the limited demand.

This isn’t the first time this year Apple has suffered from supply issues, though the continuing pattern seems to indicate that perhaps the company should focus on increasing its supply capabilities in 2014.
