The ability to manufacture MacBook Pro models at its Shanghai site remains seriously hampered despite the easing of lockdowns.

According to the Taiwan-based supply chain website, only 30% of production capacity has been restored at the company's Shanghai site.

Quanta is the sole assembler of Apple's 14- and 16-inch MacBook Pros and the machines are primarily made at the ODM's Shanghai plant. Quanta vice chairman CC Leung on April 30 pointed out that the company's Shanghai plant has restored around 30% of its capacity and is eyeing to raise the percentage to 50% gradually.

Many downstream assemblers are likely to have resumed their production lines, but many still face insufficient supplies of components for the same reason.

Due to limited production capacity caused by chip shortages, Apple customers have been facing lengthy delivery times for several weeks. The delivery estimate for the 14-inch MacBook Pro and the 16-inch MacBook Pro is currently June 29 - July 14.

The same dates apply to the Mac Studio, although the 10-Core/24-Core CPU/GPU configuration fares better with a May 17 - May 24 delivery window. Availability for the MacBook Air, iMac, and Mac mini are unaffected by the constraints, while Mac Pro depends on configuration options, but some do run into June.

Apple has already switched its transportation from marine to air to shorten the shipment schedules in the face of disrupted logistics in China, but only a limited number of shipments have moved to air transportation, which is causing the current shortages.

Apple said last month that it will be difficult to make enough product to satisfy strong consumer demand as the year progresses, and this will affect revenue in the June quarter.
