    After installing Sierra Beta 3 on my MacBook Pro 15" (mid-2015) with GPU the device will self-reboot almost daily one or two times while sleeping, it is very annoying, I did not have this problem with Beta 1 or 2, I think it was introduced on Beta 3. My installation is fresh not an upgrade, any feedback on potential root cause or just wait until Beta 4? As a side note I have a MacBook 12 (2016) with the exact same configuration and applications installed and the problem is NOT there, so it seems is only related to the HW in the MBP 15.

    What does the crash log show in console for the presumed kernel crash?

    I've had similar in PB2 with usb mass storage issue with SD card I think.

    Yep, looks like another USB mass storage crash similar to mine. Report it. I've done so.

    How did you manage it in the mean time? If there a way to avoid it?

    I only rarely sleep my laptop, so it's mostly an inconvenience.

    And during the night you turn it off?

    How did you configure it in Power Settings, because last night I selected "prevent sleep when turning the display off" and it rebooted anyway

    That's how I leave my Mac, I don' ever put it to sleep. I've done this for my MBP for years on end, without any issues.

    How do you avoid the MBP to sleep when you close the lid?

    Thanks, I just found Amphetamine at the MAS, it seems to be newer than Caffeine,

    could be, I use an iMac now, so I have no such need for those sort of apps.

    @brosenz if you do the following, subsequent .panic files will contain more human-readable information.

    1) In Terminal, run the following command:

    sudo nvram boot-args="keepsyms=y"

    2) restart the Mac.

    That command stores a useful boot argument in NVRAM. When you no longer wish to benefit from that stuff, reset NVRAM.
