Apple Discontinues High-End Mac Models Amid M5 Speculation

Apple has stopped accepting orders for several high-memory configurations of the Mac mini and Mac Studio on its U.S. Online storefront. As of April 11, 2026, these specific high-end models are listed as currently unavailable, a move that coincides with a global shortage of memory chips and speculation regarding upcoming hardware refreshes.

The unavailability specifically targets variants equipped with the largest amounts of unified memory—the integrated memory architecture used in Apple Silicon that allows the CPU and GPU to share a single pool of data.

Affected Mac Configurations

The stock issues are concentrated on the most expensive, high-specification builds. For the Mac mini, configurations featuring 32GB or 64GB of unified memory are currently unavailable for purchase.

The Mac Studio is more heavily impacted, with configurations featuring 128GB or 256GB of unified memory now removed from the ordering options. This follows a trend that began in March 2026, when Apple completely removed the top-tier 512GB RAM upgrade option from the Mac Studio lineup.

during the March transition, Apple increased the price of the step-up from 96GB to 256GB of RAM by 25%, raising the cost to $2,000 USD.

Industry Context and Supply Chain Pressures

The sudden disappearance of these models is linked to a severe, industry-wide shortage of DRAM (Dynamic Random Access Memory) chips. This shortage is being driven by the explosive demand for AI infrastructure, which requires vast amounts of high-speed memory to function.

The impact of this shortage is evident across Apple’s professional line. In March 2026, the removal of the 512GB RAM option for the Mac Studio was attributed to skyrocketing RAM chip prices and supply constraints.

Beyond the online store’s currently unavailable status, other available models are experiencing significant shipping delays. In some cases, customers are seeing delays of several months for machines that are still listed as purchasable.

Broader Product Discontinuations and M5 Transitions

These memory-related shortages are occurring alongside a broader phase of product transitions at Apple. In March 2026, Apple officially discontinued the Mac Pro tower, ending a product line that had existed for nearly 20 years.

Other hardware adjustments made in March 2026 include:

• The 14-inch MacBook Pro with the M5 chip and 512GB of storage was discontinued. New 14-inch and 16-inch MacBook Pro models with M5 Pro and M5 Max chips now start with a minimum of 1TB of storage.
• The Pro Display XDR was discontinued following the release of the Studio Display XDR, which serves as its replacement.
• The M5 MacBook Pro starting price for the lower-end 14-inch model increased to $1,699, up from the previous $1,599 for the 512GB configuration.

The timing of the Mac mini and Mac Studio stock issues has led to speculation about an imminent hardware refresh. Reports indicate that an M5 chipset refresh for these desktops is expected, which may explain why Apple is limiting the availability of current M3 and M4 based high-memory configurations.

This pattern of unavailability often precedes a total discontinuation or a replacement by a newer generation of hardware, similar to the trajectory seen with the Mac Pro at the end of March 2026.
