Earlier today I converted an old quad G5 to use air cooling. It brought back to life a system that wouldn't boot at all before the conversion. I was able to install leopard without issue. But it boots to safe boot every time and has since the first boot after installing Leopard. I performed the apple diagnostics and everything passed. I reset the PRAM and it still boots to safe boot every time. I have no idea how to get it out of safe boot or what logs to read to find out what could be causing the issue. Any suggestions would be appreciated.
