    Hello All,

    Can anyone put this in "English" for me? My iMac (17in 1.83 CD 2G Ram) screen went grey and I was prompted to restart. Any help would be greatly appreciated.

    This is what is called a "kernel panic" in OS X. It's relatively rare. Basically, it means that a series of events either generated sufficiently unexpected results or was sufficiently unpredictable, that the kernel (the very core of the operating system) decided it was safer shutting down immediately than letting it go on. It's the "way" in which OS X computers crash -- analogous to blue screen of death or sudden unexpected rebooting of Windows computers.

    It's a relatively rare phenomenon. When it does happen, it can be because of bad hardware, or occasionally because of some funny software (although that's relatively rare).

    When it's because of funny software, that software is usually implicated in that "backtrace" segment of the crash report that you posted.

    Since there wasn't any such, I would suggest you write it off as a fluke for now, and do nothing. If it happens again, however, it's time to explore whether you recently installed new hardware that might be defective, or whether there's some kind of problem with your Mac.

    Thanks for the quick response. Everything seems fine since the restart. It does seem rare since this is the first time in since I have had the machine (almost 1 year). Again, Thanks!
