Only one had a timestamp that was at at most a few minutes from when the crash happened: " Google Chrome Helper (Renderer)_-082350_MY-MACHINENAME.wakeups_resource.diag". None of them had a suspicious filename extension (eg. After the crash, the directory had a bunch of files. I cleared out the /Library/Logs/DiagnosticReports directory, and used the machine normally until the next crash. I have noticed at least one spike in CPU temperature before around the time of a crash, but I haven't been able to see that consistently. Could it be a thermal issue that happens so fast, the system crashes before the sensors log the problem? I am not doing anything super-taxing to the system. I do notice that when the system crashes, these no longer update. No change.įan RPM's and Die Temps appear normal. I've tried switching from Chrome to firefox, and disabled dropbox. I've tried not using some Applications that are long-running. I am on Catalina now, but this has been happening even with the previous OS, Mojave. I've wiped the machine and re-installed the OS about 3 times. I've run Memtest86, it passes all four passes. Is it possible there's no clues in the logs? I am looking for "grave" sounding messages, but I honestly don't know what, exactly, to look for. The problem is there's A LOT of messages. I've tried sifting through the logs looking near the time of the crash, and I don't notice anything obviously strange, basically just normal looking logs and then boot-up messages. Is it correct to assume that this means it was not an application that crashed? Here's what I've done so far to troubleshoot:Īfter power-cycling, I go into Console.App, and select "Crash Reports" on the sidebar, it is always empty. The system crashes this way usually at least once and often a few times per day if I use it a lot. What I normally do is just power cycle the iMac as soon as I hear the fans spin up and the applications become unresponsive. If I keep waiting, the screen goes black and if I wait a longer time the black screen gets a circle with a slash through it. Eventually, I get the "rainbow circle" (beach ball?) mouse cursor and I can't do anything else other than move the mouse around. I am not even able to restart the iMac from the Apple menu (it just doesn't respond). When the fans spin up like this, the applications I am using (typically Chrome, but others too), will work for a little while, ~30 seconds, and then become unresponsive. *All delivery times are estimated unless stated.I've been having an intermittent problem with my late 2013 27" iMac for more than a year now and it seems to be getting more frequent.īasically, I could be doing anything on my iMac (or nothing at all!) and I suddenly hear the fans spin up to what sounds like max speed.
