For users running macOS Big Sur (11.x) who encounter this error:

Referenced from: ... (which was built for Mac OS X 13.0)

Starting from version 2.1.113, Claude Code requires macOS 13 (Ventura) or later.

How I found this

Binary search testing between my working version (2.1.14) and latest (2.1.121):

• 2.1.112 ✅ works

Hope this helps others on older Macs.
