My 2014 mac book pro keeps restarting. After doing a google search I found a few solutions which didn't help. I am attaching the error report , if anyone can understand the root cause please let me know.

i tried solutions found on google like booting it in safe mode and trying to recognize the problem

Also uninstalled 3rd party apps and extra peripharels but still it keeps restarting

Also alot of people say that this could be a logic board issue but i want to try all the possible software related issues before i go for the big picture

    Does it panic after you do a clean reinstall or follow Apple’s guidance - support.apple.com/en-us/HT200553. For this to be open here, we would need a clearer question on what you did.

  • Yes i have cleaned the hard disk and installed the OS again but it was of no use

  • It can be time consuming to isolate, here is my best advice if you don’t want to pay someone else to do the work or work with Apple support to narrow down / repair your gear if that’s the eventual cause.

  • I tried to do the advice you suggested, I am only left on trying to change or clean the RAM. If that doesn't work I will have to change the computer

This type of kernel panic is most often caused by a defective RAM module.

The kernel panic is caused by a "general protection fault" in kernel mode. This means that the kernel (the core of the operating system) tried to access memory addresses that aren't mapped to physical RAM.

The cause of this is an invalid pointer. A pointer is basically a number stored in RAM that works as an address and "points to" a different piece of the system memory.

Invalid pointers can be caused by software bugs. However, a bug that causes a kernel panic every 2-3 minutes no matter the activity would almost certainly have been discovered by other users. Those type of software bugs that cause kernel panics are usually triggered by a specific action (such as inserting an external peripheral), and not something just happening randomly.

If you have third party kernel extensions installed - disable them to test if they have any part in the kernel panic. It is also a good idea to boot up in Recovery Mode and confirm that the kernel panics also happen here, in order to rule out third party software as a cause.

Invalid pointers can also be caused by defective RAM. This I think is the most common cause for invalid pointers happening "randomly" in kernel space with a production kernel.

There are also other, less common, causes of invalid pointers, such as for example a defective CPU, a damaged memory bus, and defective PCIe DMA units.
