[QUOTE="Randy B. Singer, post: 1946678, member: 190607"] I very rarely find a panic log to be helpful in diagnosing a kernel panic. However, this article may help with that a bit: [URL unfurl="true"]https://eclecticlight.co/2021/07/05/how-to-recognise-and-diagnose-kernel-panics/[/URL] In my experience, I'd say that about 80% to 90% of the time kernel panics are due to a hardware problem. In order of likelihood, that problem is usually: - bad third party RAM - a problematic USB hub - a peripheral that your Mac doesn't like for some reason (sometimes just a poorly attached cable, or a bad cable, is the problem) If you have very recently added new software, especially something that alters the system at a low level, such as anti-virus software, or something that changes the look and/or function of the Mac interface, I would suspect that first. Uninstall that software and see if things get better. (This type of software typically requires an uninstaller to completely disable. Just dragging the application, or the application's folder, to the Trash won't disable it.) I'd go so far as to say that if you are running commercial fully interactive anti-virus software that the first thing that you should try is fully uninstalling it with the developer’s uninstaller. If that isn't it, I would restart the Mac with the Shift key held down (invoking a Safe Boot, with all kernel extensions disabled) and see if the problem is gone while running in Safe mode. If the problem is gone while in Safe mode, the Kernel Panics are probably due to a software problem. If it persists while in Safe mode, the problem is most likely hardware related.
