Mac kernel panic
Mac system are widely known for its stability, best data management and easy accessibility of stored data. Of course the system is not free from damages and data loss but, also there are many solutions to get over the issue. Most corruption or crashes on Mac OS X affects just one program but if users experiences kernel panic then it leads to a system wide crash. The kernel panic on Mac system occurs without any warning and when it occurs user cannot do anything but to restart the system and thus the program or data opened at the time cannot be saved.
How the Kernel Panic appears?
A kernel panic in Mac is an action taken by the operating system when it finds an internal fatal error and from which it cannot safely come out. The kernel panic normally results into complete system screen becoming dim and a message box is displayed to users in various languages notifying user that the Mac system needs to restart (by holding the Power button for sometime to turn off the machine and then start it again).
Again after the system restarts a message appears for 60 seconds informing user that the Mac system restarted because of some problem.
What causes the Mac kernel panic?
There can be number of reasons that results into the Mac kernel panic issue including some temporary ones that can be seen just once such as an application written poorly, add-ons, plug-ins, drivers, and several other software components.
Here are some general causes of occurrence of kernel panic:
- Incompatible or damaged system RAM.
- Corrupted or obsolete kernel extensions.
- System drivers corrupted or damaged.
- Corruption in hard disk, damaged directory, bad sector, etc.
- Wrong permission on system files and folders.
- Space not available on hard disk or RAM.
- Software or hardware installed incorrectly.
- Program error or defective CPU.
- Incompatible hardware.
More often the kernel panic occurs during some unusual conditions such as when few apps running while most of system memory is in use. Though, simply restarting the system corrects this issue but many times it leads users to serious data loss.
How to fix the repeated kernel panic?
Under some serious situation it happens that the kernel panic is repeated every time user restart the system. In that case the Mac OS X gives up in the fifth tries and then the machine shuts down. However, there are ways to troubleshoot repeated kernel panics as below:
Safe boot – Restart the Mac system by holding on shift key until gray Apple logo appears. Doing so temporarily disables the problematic software and runs several cleanup process.
Update software – Use Apple Software Update to update any obsolete or outdated softwares like drivers or kernel extensions to fix the problem of repeated kernel panic.
Update firmware – Install the available software updates for Mac.
Check system disk – Be sure that the startup disk of Mac OS X has at least 10 GB free space. For this several unnecessary programs or files can be removed from the disk. Now, to fix any error on disk run disk utility, select startup disk and then click on repair disk.
Correct peripherals – In case if the problem still persist then shut down Mac system and detach everything except keyboard, pointing device, and display if they are not built-in. Now turn on the Mac and if the problem gone repeat process again, just reattach one device at a time. If after attaching any hardware the problem occurs then the problematic device can be known easily.
Check RAM – One of the common reason causing kernel panic is the defective RAM. At times few defects in RAM manifest itself after some time. If any extra RAM from the market is added to Mac machine then user should turn off Mac, remove the market RAM and then restart system again. It may make then kernel panic disappear.
Software issue – If none of the above method helps then better install a new copy of the Mac OS X then boot hard drive and run software update to have all latest updates. Now run system using this hard drive and if the kernel panic issue is gone then the problem is surely due to the software issues.
However, in case if after reinstalling a fresh copy of Mac operating system the data saved in the hard drive is gone or missing then user can recover back all data using a very advanced and sophisticated Mac data recovery software.
