- Mac OS X Tiger (10.4) or Leopard (10.5)
- Xcode 2.5 (Tiger) or Xcode 3.1 (Leopard)
- GCC 4.0 with AltiVec support
gcc -O3 -mcpu=7450 -maltivec -o program program.cgcc -O3 -mcpu=970 -maltivec -o program program.ccd altivec_llm
make -f Makefile.ppcTiger ships with Python 2.3. The *_ppc23.py scripts are compatible:
python rustchain_miner_ppc23.py
python rustchain_wallet_ppc23.pyTiger's OpenSSL only supports TLS 1.0. The shims enable TLS 1.2:
gcc -o tls_shim openssl_tls12_shim.c -lssl -lcrypto| Machine | RAM | Status |
|---|---|---|
| Power Mac G5 | 2GB+ | Best performance |
| PowerBook G4 | 1GB+ | Works well |
| Power Mac G4 | 1GB+ | Works |
| iMac G4/G5 | 1GB+ | Works |
| Mac mini G4 | 512MB+ | Limited |
- Use AltiVec - 4x speedup on vector operations
- Optimize for your CPU - Use
-mcpu=7450(G4) or-mcpu=970(G5) - Disable Spotlight - Frees up CPU cycles
- Use RAM disk - For temporary files
- Close Dashboard - Saves memory on Tiger
- ppc-compilers - GCC 7, GCC 10, Perl 5.34 for PowerPC
- rust-ppc-tiger - Rust compiler for PowerPC
- llama-cpp-tigerleopard - llama.cpp for Tiger/Leopard
- claude-code-power8 - Claude Code for POWER8
- llama-cpp-power8 - llama.cpp for POWER8
- Scott (Scottcjn) - Creator, architect, hardware lab, project direction
