What software caused my MacBook to panic reboot?

My MacBook Pro running High Sierra spontaneously rebooted while I was moving the mouse using Chrome as focus to access GMail.

Upon reboot I got this panic report:

Is there any clue in there what went wrong or what program caused the issue?


From my perspective, this is a bug in Apple's code and you can't do anything about it, other than updating whenever a new version of macOS is released. This instability has surfaced on my stable MacBook Pro 15" Late 2013 after the upgrade to macOS High Sierra.

Just make sure you send the crash reports to Apple and some day, somewhere in the future they will fix it (hopefully).


From the looks of it, it seems like your MacBook has some sort of conflict with 3D acceleration (accelerator tried to use resource that is currently used). You seem to have an external GPU, so try removing it. If that still doesn't work, you might have to reinstall your system or restore from backup, because it is possible that your system files are damaged.
