Trying to understand Kernel Panic

My computer keeps on freezing. this is one of the reports I got:

We've already told you the SSD is most likely bad. Each of those Kernel Panic reports is always referencing the SSD in various ways. There is a slim chance the Logic Board could have an issue, but the SSD failing is much more likely from my personal experience on repairing these Apple laptops. IIRC the 2013 model even had a free SSD repair program which has long since expired. See my previous post for a link to a third party OWC Aura SSD that is compatible with this laptop.

You can post your Kernel Panic report in their entirety here, preferable three separate reports in three separate "Additional Text" box for ease of reading and comparison, (see menu below.) A single report may be useful but does not establish a trend for a meaningful diagnosis.


Kernel Panic reports can be found /Library/Logs/DiagnosticReports

From the Finder>Go>Go To Folder, copy and paste:

/Library/Logs/DiagnosticReports


ends in .panic post the whole report.

As @etresoft mentioned you have a bad SSD which needs to be replaced. To be accurate the SSD is most likely bad, although the Logic Board could also be at fault. In my own personal experience though the SSD is the most likely culprit.


If macOS 10.13+ has already been installed on this laptop, then you can purchase an OWC Aura SSD and replace the SSD yourself. OWC includes the necessary tools as well. You will only be able to use macOS 10.13+ on this laptop when using the third party SSD.

Hi,

Page fault tends to be memory related issue. If your MacBook Pro is memory upgradable, open back panel and reseat memory modules could solve the issue.

If it doesn't help, run Apple Hardware Test or Apple Diagnostics if it reports something.

You would replace memory modules.

If your MacBook Pro is not memory upgradable, memory soldered on logic board, you'd better contact Apple support or take your MacBook Pro to opened Apple Authorized Service Provider to be examined it.
