Since launching the redesigned Mac Pro in December, Apple has struggled to keep up with demand and as recently as February was quoting nearly two-month delays in estimated ship times on new orders.
The situation appears to be improving, however, as current Online Apple Store estimates show new orders will be shipped out in three to five weeks for all configurations. When shipments were at their worst, Apple was quoting month ranges instead of weeks.
Ship-by dates have been slowly improving over April, with checks earlier in the month showing estimates pegged at 5-6 weeks, which moved up to 4-6 weeks on Apr. 11 and finally 4-5 weeks on Apr. 18.
Customers interested in the most powerful Mac ever will still need to place orders through Apple's online storefront, however, as in-store supplies are non-existent.
While Apple is still building up inventory, authorized resellers like MacMall and Adorama have limited supply of certain configurations as seen in AppleInsider's live Price Guides.
