Overview
- Apple’s online store now marks select builds as unavailable, including Mac mini M4 with 32 GB RAM, Mac mini M4 Pro with 64 GB, and Mac Studio M4 Max with 128 GB, with some reports adding the M3 Ultra model with 256 GB.
- Delivery windows for many remaining configurations have stretched from weeks to as long as four to five months, with some store pickups not shown until September.
- Apple has given no reason or timeline for a fix, and one Mac Studio option with 512 GB RAM was removed in March without a replacement.
- Industry watchers point to a global crunch in RAM and NAND chips or to Apple controlling stock before expected M5 desktops, though any product refresh remains unconfirmed.
- Higher-RAM Macs are built to order and use memory packages bonded to the main chip, which Apple sources from partners like Samsung, so parts shortages can quickly stall custom builds while some retailers still show stock and lower prices.
