MacBook Kernel Panic

When I use my MacBook pro it suffers from a kernel panic. This kernel panic happens only when the AirPort interface is turned on, and is joined to a Wi-Fi network.

Is there a fix to this?

How to factory reset macbook pro


There's no real reset, though you can reset many basic settings by opening the System Preferences. However, in certain situations, you may want to zap the PRAM or NVRAM. You do this by turning off the computer and holding down the option, command, P, and R keys before the Apple logo appears (usually while the screen is still grey). The computer will chime (loudly) and begin the startup sequence again. This is useful for resetting certain basic settings and to help recover from a kernel panic (a type of crash that can cause problems again on restart).

My mac gives me a panic kernel when I try to do something with it. How do I fix this problem


Hi
You can try to zap the parameter Ram (pram). Turn off your Mac, then turn on your Mac and immediately press and hold the Option-Command and the P and R keys. You must press the keys before the gray screen appears. Continue to hold the keys until the computer restarts, and you hear the startup sound a second time.
Hope this helps

Mac laptop screen froze with message stating must turn off laptop


font.f1 { font: 12px Helvetica; } Thanks for asking your question with Fixya Support. I will be glad to assist you.

What you are experiencing is what is called a Kernel Panic.
A Kernel Panic, is a internal fatal error, detected by your system from which it
cannot recover from safely. Such an error can be the result of a software
function or operation failing to execute as it normally does, or halting without
warning, or even a hardware component, suddenly ceasing to operating
or simply shutting down. In either scenario, the system will display the frozen
black and white screen with the languages text listed.

Normally a simple reboot of your Macbook Pro will resolve the issue, but in some cases it can take a specific procedure to correct and prevent a kernel panic from occurring again.

So here are a few procedures you can use to resolve and prevent further kernel panics:


• First, hold in your power button for approximately 10 seconds to do a hard shutdown, if your Macbook Pro is still turned on.

• Once your Mac is shutdown, you will need to perform what is called a PRAM reset (Parameter RAM)

• Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously .

• Turn on the Macbook Pro.
• Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.

• Now, hold the keys down until the computer restarts and you hear the start up sound for the third time.

• Release the keys and allow the Macbook Pro to start up.

If your Macbook Pro starts up normally and does not go into another kernel panic, then you should be able to resume normal session activity on your Macbook Pro.

However, should the kernel panic return, then you can use an SMC Reset to correct the kernel panic:

-SMC RESET-
The System Management Controller is an integrated circuit (computer chip) that is usually on the logic board of your Mac portable.

It is responsible for power management of the computer. It controls back-lighting, hard disk spin down, sleep and wake, some charging aspects, trackpad control, and some input/output as it relates to the computer sleeping.

Shut down the computer.
• Disconnect the MagSafe power adapter from the computer, if it's connected.
• Remove the battery.
• Press and hold the power button for 5 seconds.
• Release the power button.
• Reconnect the battery and MagSafe power adapter.
• Press the power button to turn on the computer.

Once again, when you are back up to your main desktop, resume your normal session activity.
At this point there should be no further issue a the kernel panic rearing its ugly head once again.

If it does, then you will need to take more intensive steps such as inserting your Mac OS X installation disc and booting up to that disc and running Mac OS X's Disk Utility, to repair the hard drive and permissions of the Mac OS X system you are using.

I will leave you with that procedure, in the event you need to run Disk Utility:

Insert your Mac OS X Startup disk
•Reboot your Mac
•At the Apple Chime, press the C key and hold it until you see a White screen, gray Apple and eventually a Spinning gear.
• Release the C key only after you see the Spinning gear.
•Mac will boot from the start up disk to the Installer environment
• From the Installer Menu bar, click Utilities > Disk Utility and open up Disk Utility application.
• Click on on the hard drive at the top of the window in the left sidebar and
• Select "Repair Disk"
**Let Disk Utilities run this repair the disk until completion
• At the end of this process, reboot your Macbook Pro
Return back to you main desktop and again, resume your normal session activities.

Any more kernel panics after this, you may want to consider taking your Macbook Pro in for service at your local Apple retail store Genius Bar or local Apple authorized service provide in your area.

I hope this information proves helpful for you.

Regards,

-Mactechtrainer

Why my ibook cannot boot to desktop.but only stop at the grey apple display


What is happening is the mach kernel is hanging during bootup. This is likely caused by a kernel panic. Boot-time kernel panics are caused by the following things:
  1. A botched software update
  2. A badly behaving hardware device
  3. Flaky RAM memory.
  4. You are WAAAY too low on free disk space.
Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel, and report if it says anything but Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
If DU reports errors it cannot repair you will need to use a utility like Tech Tool Pro or Disk Warrior

If you can make it this far, it is likely that your hard disk and the majority of your computer hardware are functioning correctly and your issue is software related.

Kernal panic alert screen will not respond


Well, if you erase the wrong files, you'll sure get a kernel panic.
To power down your PowerBook when there is a kernel panic on the screen (or any frozen state) you have to hold the power button for 10-15 seconds until the Mac shuts off. Then you can restart it.
If you deleted too many of the wrong files, it may not restart to your satisfaction. :-(

I unplugged my maclaptop before it could configure and now it wont restart i think its in kernel panic mode...SOS!!!


I would disconnect the power cord and battery (just flip it over and there should be relatively easy access to the battery) and then turn it back on. it should come back online and allow you to configure everything. if it's still crashed out, I would use the 10.5 disc they include with your new macbook and follow its prompts to reinstall. if it asks what kind of install you want, erase and install would be it.

I hope that you are just able to power cycle it though.

Apple mac g4 laptop wont come on


Kernel panics are not what you have, you have a flashing question mark, it indicates there is a problem with either the hard drive or the operating system on the hard drive.

Kernel panics are different, the unit tries to start and then the unit crashes with a "kernel panic"
