Apple unveils the M6 and M5 Ultra chips alongside updated Mac mini and Mac Studio desktops. The company says the M6 is its first 2nm chip, while the M5 Ultra is designed for the highest-end professional work, including AI processing, 3D rendering, and advanced video production.

Apple opens pre-orders for the new Mac mini and Mac Studio, with most configurations set to become available on September 22. Orders begin through Apple’s online store and app, and the same date marks the start of shipments and in-store sales for the new desktop lineup.

The updated Mac mini starts at $899 and keeps its compact form while moving to either an M6 chip or an M5 Pro chip. Apple frames the upgrade around stronger everyday performance and better on-device AI capability, with gains in CPU, graphics, and machine-learning workloads.
