Overview

• AppleInsider cites internal Macs labeled J873g and J873s, which align with standard M5 and M5 Pro Mac mini configurations.
• Multiple reports indicate the update is a specification bump with no visible redesign, retaining the smaller M4-era footprint.
• AppleInsider also reports internal testing of macOS 26.1, 26.4, and 27 as part of ongoing development.
• Timing remains unclear, with MacRumors noting recent reporting that points to an update arriving in early 2026 rather than late 2025.
• AppleInsider positions the Mac mini refresh within a broader M5 rollout expected across additional Macs through 2025–2026.
