MacBook randomly crashes

Hi All,


I have recently moved from Windows to Mac and still learning. I have an issue with random crashes. I've got a MacBook Pro 15 inch (Mid-2012 i believe) which came with a new HDD and fresh install of High Sierra. I am using it with an external monitor and a DisplayLink too (so i use two monitors) when at home. I've lifted the below logs from when a crash has happened. As well as the below there does seem to be a recurring log about com.apple.xpc.launchd[1] with a log that says the "service only ran for 0 seconds. Pushing respawn out by 10 seconds" but this seems to be ongoing so am not sure if this is causing the crash or not.

Any help is appreciated!

So I worked out what it was; the Skype for Business client seems to have been causing the crashes. Although I downloaded the latest version when I first installed it I noticed there was a new version so downloaded and installed that. I also upgraded to Mojave (well, actually I upgraded to Mojave first but this didn't cure the problem).

Sorry about taking so long to get back to you.


First uninstall the Symantec Anti-Virus Security software by following the developer's instructions unless it is required by your school or employer. AV software and other cleaning apps are not needed on a Mac and usually causes more problems than it solves plus it impacts system performance. If AV software is required, then see if you can use MalwareBytes instead.


I'm not familiar with Devolo so I don't know how it behaves. The Symantec software is known to cause problems though.


You should update the MX300's firmware if you haven't done so already. Pre-M0CR060 firmware had some issues. You can create a bootable SSD firmware updater USB drive using Etcher. Option Boot the USB and select the orange icon labeled "EFI".
