I have an iMac w/ OSX, occasionally it hangs on boot (doesn't even have the apple logo or the animated spinner icon) and I would like to troubleshoot this to see what the problem is. I have to hold the on/off button so it shuts down, and then the next time it almost always boots fine.
Is there a way to have it display unix-style verbose text during bootup?
A friend of mine said I should look at /var/log/system.log and I did but couldn't see anything obvious this time. I'll try to be more thorough next time it happens, but it would be more helpful to see where it locks up.
edit: Please note -- 95% of the time my computer boots fine and runs fine. I just want to figure out what's going wrong the rest of the time.
update: happened again. Got the chord and the gray screen, no apple logo, no /var/log/system.log entry. It is an Intel Mac. I'll try the troubleshooting docs....
