My mac is showing cycling kernel panic at boot time and I am trying to figure out what is causing this. Any help would be appreciated. When I try the safe boot (with shifty key), my mac boot with no problem. So I tried the verbose boot (command-v) and the terminal is showing something and then erase them. The mac is repeating this since it is in the cycling kernel panic mode. And there is no way to pause the terminal to see what is going on. So I tried singe-user boot (command-s) and this boot is very different from verbose boot. It does't go through the kernel panic loop and simply show the prompt of %root. So I typed "sudo dmesg | more" but it shows the system log of single-user boot not the verbose boot. So there is no way to get the system log of verbose boot. Is there a way to stop the verbose boot from kernel panic loop so that I can get the system log from "sudo dmesg | more"?
