As noted by 9to5Mac, some Mac mini and Mac Studio configurations are now completely out of stock on Apple's online store in the U.S. as of this writing. Mac mini configurations with an upgraded 32GB or 64GB of RAM and Mac Studio configurations with an upgraded 128GB or 256GB of RAM are listed as "currently unavailable" on the storefront, meaning they can no longer be ordered at all.
