@JkNML and @argentum - Thank you, I will definitely track and provide that information for future occurrences, if any.
@luckman212 - kernel panic (I had to look that term up). The error report that is generated on restart, and then sent to Apple, mentions something about Obsidian and wheel lock and behavior?
To start, I’m back to using the default theme and I’ve uninstalled the theme-specific community plugins. However, I’m still using all my other installed community plugins. If my system crashes again, I’ll starting turning them off, as well.
I have a new macOS laptop on the way that will become my main Obsidian machine. Perhaps that will resolve the problem.
