Description

OpenClaw host detection reports the wrong macOS version on macOS 26 (Tahoe).

Expected: macOS 26.5.1 (Tahoe)
Actual: macOS 15.x (Sequoia) — derived from uname -r returning 25.5.0

$ sw_vers
ProductName:    macOS
ProductVersion: 26.5.1
BuildVersion:   25F80

$ uname -r
25.5.0

Root Cause

OpenClaw appears to determine the macOS version by mapping the Darwin kernel major version (uname -r) directly to the macOS major version (Darwin 25 → macOS 15). This mapping broke with macOS 26 (Tahoe), which uses Darwin kernel 25.x.

Suggested Fix

Fall back to sw_vers -productVersion for the macOS product version instead of relying solely on uname -r. The Darwin kernel version and macOS marketing version are no longer in sync starting with Tahoe.

Environment

• OpenClaw 2026.6.8
• macOS 26.5.1 (Tahoe) 25F80
• Darwin 25.5.0
