Kernel panic. Computer keeps rebooting.

My MacBook recently got a new screen and since has problems of occasionally rebooting the computer. I don't know the source of the problem as I can't understand the system log. Can anybody help?

Page faults indicate a memory issue of some sort...

To trouble shoot further you can:


—Try a SafeBoot https://support.apple.com/en-us/HT201262



Takes noticeable longer to get to the login screen, does a 5 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc.

Login and test. Reboot as normal and test. Caches get rebuilt automatically.


In Safe mode third party system modifications and system accelerations are disabled, it removes malware, etc hampering smooth operation, however a reboot will put it back to normal mode.


This test will tell you if third party interference; extensions etc are not loaded in safe boot mode.




You can try the user Diagnostic...not as definitive as Apple's own AST2 (Apple Service Toolkit) back bench diagnostic, but may kick out an error code.

VPNs are the other "troublemaker" I had to remove from my standard list of common troublemakers just before posting.


VPNs promise improved integrity, and simply do not deliver on that promise, not even a little. Instead, User-initiated VPNs tend to damage performance and system stability.


The exception is a managed use of a VPN for Corporate/Institutional access.

There are three quick take-aways from any panic report.


1) The panic-reason,


2) the extensions present at the "scene of the crime", and


3) the BSD process in which the problem occurred.


One more item that is important is the names of any third-party Extensions you have added. They are shown FIRST in the extensions loaded section


————

Take look at your other reports. What you are trying to determine is whether there is a TREND.


Case A) There is a trend: This same panic occurs in each case, with the same extensions present, in the same BSD process. A trend can indicate corrupted software or a Hardware problem that can be tracked down and solved.


Case B) There is a decided NON-Trend. The panics occur "all over the Map" for different panic reasons and in different BSD processes, with different extensions present.


A Non-trend suggests you may have RAM memory problems. MacOS slightly randomizes the load point of key routines on each startup, as a hedge against fixed-address attacks. This causes a marginal memory cell to move into different routines each time your Mac starts up.


>> Based on that, you have a RAM memory problem.
