Many of the Mac OSX or similar Unix like operating system
users may face a type of error known as “Kernel Panic”. When
this error message get displayed, you need to restart your
system as your system stops working and require restart.
Since the system is not in the state that you can perform
the normal restart and therefore you need to force restart
the computer. At that time if you were in the middle of the
process or working with some kind of unsaved document then
it will also be lose.
The general causes of kernel panic in Mac OS X include:
1. Defective or incompatible RAM
2. Incompatible, obsolete or corrupted kernel extensions
3. Incompatible, obsolete or corrupted Drivers
4. Hard Disk corruption that include bad sectors,
directory corruption and other hard disk errors
5. Incorrect permissions on System files and folders
6. Less RAM or Hard Drive Memory
7. Defects in hardware, CPU or programming errors
8. Incompatible hardware
Other than these the Mac Kernel Panic occurs when the core
component of Mac (kernel) gets an unexpected user
instruction and fails to handle that instruction properly.
Kernel Panic Fix in Mac OS X
It is monitored that the kernel panic does not come
frequently but if it’s occurred then restarting the computer
will solve the problem but if the error occurs due to the
corrupted/incompatible system resources then reinstall Mac
OSX. When you go for the fresh installation of Mac OSX, the
primary volume need to be formatted and all the data present
over that volume will be lost. This condition can be a bad
dream as you can lose lots of important data which you had
saved on that system volume.
