You can turn a cluster of Macs into an AI supercomputer in macOS Tahoe 26.2

Who needs a revamped Mac Pro when you can just turn several Mac Studios into a unified computing system? With the upcoming macOS Tahoe 26.2 release, Apple is introducing a new low-latency feature that lets you connect several Macs together using Thunderbolt 5. For developers and researchers, it's a potentially useful way to create powerful AI supercomputers that can run massive local models. That allows four Mac Studios, which can each run up to 512GB of unified memory, to run the 1 trillion parameter Kimi-K2-Thinking model far more efficiently than PCs with power-hungry GPUs.

While we’ve seen Thunderbolt Mac clusters before, they were limited by slower Thunderbolt speeds, especially if they required a hub (which could reduce speeds to 10 Gb/s). Apple’s new feature allows for the full Thunderbolt 5 connectivity of up to 80Gb/s ...
