The most extreme cause is faulty software. A kernel panic can also be caused by having incompatible or corrupted hardware nearby, including external devices connected to your Mac. If the kernel panic is caused by a known problem, a faulty computer program is identified.

The most likely cause is misuse. A kernel panic can also always be caused by corrupted or incompatible components, including external devices connected to a new Mac. If the kernel panic is still caused by a known issue, the faulty software is identified.

The Linux kernel provides the foundation for the living space of mobile computing.

The philosophy is to manage each other’s resources. So Linux:

Prevent user A from viewing user files ya b

Make sure user A is not using user B’s memory.

Ensures that buyer A does not drain the CPU of user B.

Ensures that User A’s computer does not overload User B’s devices (for example,
Telephony, GPS and Bluetooth)
