MacBook Pro keeps restarting when in sleeping mode

When I leave my MacBook Pro alone for some time, it restarts and shows this crash message.

Any help on this? Thx!!!!

Hi woualid,


It sounds like your MacBook Pro is restarting unexpectedly when it goes to sleep. We're here for you, and we want to help out.


Prior to seeing the error you provided in your post, does your Mac also display a message saying something like "Your computer was restarted because of a problem"? If so, the information and troubleshooting steps on the following page should be helpful:


If your Mac restarted because of a problem


Unexpected restarts can be caused by several things, such as software installed on your Mac, or by devices connected to your Mac. From the error you provided, it looks like the issue may be related to an accessory connected via a Thunderbolt connection. Do you have any external devices connected to your Mac at this time? If you do, does the issue continue to happen when those devices are disconnected?


Thanks!

Hi -

I don't know why this reported issue is marked as solved. I have the same issue frequently when the mac goes on sleep mode it crashes and then reboot, then crashes again. if you get away from the and go to the bathroom, and you come back to find that your laptop has crashed, then reboot and crashed again.

One way I was able to work around this issue so that I can do my work, is to use an app like `Amphetamine` to keep my session up indefinitely. That is not a fix!

I bought this very expensive hardware in May 2020 and it's not doing the job that it was hired to do. :(

See my log attached
