Apple Removes 512GB Memory Option From Mac Studio

Apple on March 6, 2026 removed the 512 GB unified memory option for the Mac Studio, capping maximum RAM at 256 GB and raising the 256 GB upgrade price from $1,600 to $2,000 (a $400 increase). Apple discontinued the 512 GB M3 Ultra configuration amid ongoing DRAM supply constraints; the 256 GB option still supports large local LLM workloads but reduces headroom for the largest models.
