Macbook Pro 15 2016, Crashes after wakeful output since the July 22 security update in Sierra.

Greetings Boulic,

Thank you for using Apple Support Communities. It seems like like you received a Kernel Panic. There are a couple things you can try that may be able to help. I would recommend you use this article to help troubleshoot the issue.

If your Mac restarted because of a problem

Please don't hesitate to let us know if the steps resolved your issue or if you need additional assistance.

Take care.

This is a direct result of having run the 004 Security Update on July 22. Please issue an actual fix. Don't tell us to use Safe Mode or reinstall our OS or somehow blame us.

An issue I'm having, besides the kernel panic on wake, and requirement to fully log in every time, is that, when putting the MBP (2016 touchbar 15" Sierra) in Sleep mode by closing the cover, the case back plane quickly becomes extremely hot. I have been simply doing a full Shut Down at day's end; I don't want to be the victim of a possible battery explosion or fire. I doubt if Apple wishes to have liability for such either. This is unacceptable.

Yikes, Thanks for confirming that the 10.12 update also causes the issue.

Apple just now pulled the 2019-004 update for Sierra after pulling the High Sierra update earlier this afternoon.

Same story on High Sierra and a Macbook Pro 15" 2016! I do hope that early Monday, Apple will have an official stand on this problem inflicted by its own Security Update.

Is anything being done before users do more damage to their computers trying every possible venue? If at least Apple could invite people to be patient by revealing that they are indeed working on a fix instead of letting everyone speculate...

I don't think there's any actual "damage" happening, at least not that I've observed, just the unnecessary and time-wasting annoyance of a cold restart with a Kernel Panic notification after every Sleep or Shut Down. Apple is customarily silent about these sorts of things, no surprise here.

It seems they released a fix.

I've got the same issue here.

A great deal of discussion started in this thread: https://discussions.apple.com/thread/250506277

I invite you to check it out every so often for updates.

Welp, looks like we are the unlucky guinea pigs.
