Claude Code for PowerPC G4 (Mac OS X Tiger)
Running Claude Code on 20-year-old Macs!
This is an experimental port of Claude Code concepts for Mac OS X Tiger (10.4) and Leopard (10.5) on PowerPC G4/G5 processors.
What's Included
| File | Description |
|---|---|
claude_code_g4.py |
Python Claude API client for Tiger |
claude.js / claude_code.js |
QuickJS-based Claude implementation |
claude_proxy*.py |
HTTP proxy helpers for old TLS |
quickjs-2024-01-13/ |
QuickJS with Tiger/Leopard patches |
The Challenge
Tiger/Leopard have several limitations:
- Python 2.3 (no modern SSL)
- Old OpenSSL (TLS 1.0 only)
- No Node.js (requires 64-bit or modern libc)
Solutions
Option 1: Python with TLS Proxy
Use a modern machine to proxy HTTPS:
python claude_code_g4.py --proxy http://modern-machine:8080
Option 2: QuickJS
QuickJS provides modern JavaScript on Tiger:
make -f Makefile.ppc
./qjs claude.js
Building QuickJS for Tiger
cd quickjs-2024-01-13
make -f Makefile.ppc CC="gcc -mcpu=7450" CFLAGS="-O2"
Hardware Tested
| Machine | CPU | RAM | Status |

| PowerBook G4 | 1.67 GHz | 2GB | Working |
| Power Mac G5 | Dual 2.0 GHz | 8GB | Working |
