Question: macOS High Sierra automatically restart issue

Hello everyone,


I bought my 2017 MacBook pro 13" with touch bar two months ago. Recently, i notice that the system restarts itself when i leave it open on my work station. This is a big issue because each time i take a break from the work i am doing, i have to save all the files. If i accidentally forget about saving one file, i will risk losing it.


Have any of you guys encountered this issue before? Did i mess up with any settings before?

MacBook Pro (13-inch, 2017, 4 TBT3), macOS High Sierra (10.13.1)

It could be some incompatible device like USB dongle or some thunderbolt attached doing it. Remove everything attached . If nothing is attached to usb c , then its hardware issue, I would call Apple Support , they are amazing within warranty period.

So after a month of crazy frustrating restarts and after erasing my iMac 4 times, I took it to an apple store and they downgraded it to macOS Sierra (of course by deleting everything once more). The gentleman who helped me over there told me that they have many customers with this issue and this is the only solution they have at the moment. They did not charge me and as always I was very happy with the service that I received.


You may want to consider this seriously!
