Hi Guys, Thank you for your time, I was wanting to ask your opinion on an issue I am having to best try and get it sorted. I have a 2017 MacBook Pro and recently its been a horrible machine to use as it keeps freezing, locking up or just glitching. The main issue I have is that I can be working away and it just reboots or freezes. When this happens i sometimes get a Kernel Report but most of the time the Kernel log only has the "*** Device Tree *** Log and no more information. The only other Kernel log I have is in the IOStorageFamily. I have ran apple diagnostics, MemTest x86 and other tests on the SSD but everything passes. So I decided to Reinstall OS X by deleting the partition table, and completely starting fresh, all was fine for about a day and then it all started again. Now, the main issue I have is that my local Apple Store is very busy and I have went to see them before in the past, they had my machine for nearly 2 weeks and said it passed all tests and gave me it back. I really need the computer for work and I would lose a lot of money if I cannot have it for 2 weeks, is there anything you could think of that I could try to test / diagnose or even convince my Apple Store I genuinely have an issue? I appreciate any advice. Thanks Jamie Update: I managed to capture a video of when the MacBook crashed when just about to watch a video on YouTube. I am sorry for the bad camerawork but I was in a hurry to capture as much as I can before the MacBook reset itself. You can see at the end of this video the computer didn't even show the message it had restarted because of a problem.
