Apple has halted new orders for several high-specification configurations of the Mac mini and Mac Studio through its U.S. online store. Specific builds featuring 32GB or 64GB of RAM on the mini, and 128GB or 256GB on the Studio, are listed as "currently unavailable." This sudden stoppage is more severe than the existing shipping delays, which already stretch one to three months for other models.

This inventory crisis appears tied less to an imminent refresh cycle and more to industry-wide supply constraints. The affected models are uniformly those requiring substantial memory, pointing directly toward a severe global memory chip shortage. Surging demand from AI server builders, which consume vast quantities of high-end RAM modules, is forcing Apple's hand on these specific builds.

Even configurations still purchasable are subject to extraordinary wait times, complicating any attempt to read this as a standard precursor to M5 chip announcements. Last month, Apple quietly dropped the 512GB RAM option for the Mac Studio entirely, further signaling supply pressures. While memory prices are reportedly easing slightly, they remain elevated above historical norms, suggesting relief for desktop purchasers may not arrive soon.

This situation forces consumers needing power desktops into a waiting pattern. While analysts speculate about M5 chip reveals at WWDC or later this fall, the immediate concern centers on securing components. Mac Studio builds requiring premium memory are effectively blocked from purchase right now, a concrete impact of the broader silicon crunch.
