While Apple's new Mac Pro was previously scheduled to ship new orders in March, shipment dates have now slipped back to April according to listings in Apple's online stores.

The company began taking preorders on the newly redesigned Mac Pro in December of last year. Standard configuration shipments quickly slipped from late December to February, with made to order models listed as shipping in January right from the start. Since then the new American-made pro system has been on constant back order and was listed as shipping in March as of last month on stock and custom models.

Initially Apple pushed the shipment dates on all models back to April in China, France, Germany, Japan and the UK, and later slid the date back in both Canada and the US as well. Many have suggested that while this may not mean the supply chain situation is getting worse being that delays have been more or less consistent, it could suggest Apple is being slightly hesitant or is just yet to get on top of things.

While Apple's storefront is experiencing significant back orders, reports suggest that third party authorized Mac dealers do have certain configs in limited supply. Apple's latest pro machine starts at $2,999, you can get a closer look in the teardown and in our Mac Pro review roundup.
