Availability date from Apple's[2] own newsroom announcement (https://www.apple.com/newsroom/2026/08/apple-introduces-new-mac-studio-with-m5-max-and-m5-ultra/): pre-orders from August 25, 2026, and it 'will begin arriving to customers, and in Apple Store locations and Apple Authorized Resellers, starting September 22'. September 22, 2026 is the shipping/on-sale day.
Apple's[1] Mac Studio tech-specs page gives the M5 Max "18-core CPU with 6 super cores and 12 performance cores" at 460GB/s, the M5 Ultra's 30-core CPU and 1.2TB/s bandwidth, the 7.7 x 7.7 x 3.7 inch size and Thunderbolt 5 ports.
MacRumors' 25 August 2026 piece is about the Mac mini; it confirms the Mac Studio was unveiled the same day only in passing ('unveiled alongside a new Mac Studio'), so it dates the unveiling but says nothing else about this product.
Macworld's own coverage of the 2026 Mac Studio M5 Max/Ultra reports the line was announced August 25, 2026 with shipping beginning September 22, 2026 (512GB configs arriving in late October) - later than the pin's stored September 8, 2026 date, consistent with the pin's "unknown" dateConfidence.
