Hi, My Mac has shut down a couple of times with shutdown code 128. I checked the following ifixit post though I am not sure if its a memory related issue since I never see code 112 and also don’t really see excessive memory activity in the Activity Monitor. How to determine Mac shutdown causes I am considering cleaning up inside the macbook pro once I confirm if its actually dusty and also do a hardware test if needed, as suggested in this thread: https://apple.stackexchange.com/question… Any suggestions? -Sharath
What is the amount of RAM your logic board have as well as the size of your drive and how much free space it has? A common issue I’ve seen is the runout of storage space on the drive! What happens here is your system needed more RAM space that it has physically so it leverages Virtual RAM on the drive. But, if the drive is overly full it can find its self hamstrung! Ideally, you want 1/3 of the drive empty for 128/256 GB drives, And for larger drives 500 and larger 1/4 free.
