Apple has removed more desktop Macs from its online store as the global memory shortage continues. Mac mini models with 32GB and 64GB of RAM are no longer available for purchase, nor is the M3 Ultra Mac Studio with 256GB RAM. The M3 Ultra Mac Studio is now available only in a 96GB RAM configuration, with higher-tier options eliminated. Both M3 Mac Studio and M4 Max Mac Studio models have delivery estimates of 9 to 10 weeks.
