Mac Os Microsoft Teams Kernel Panic
Aug 27,2019 • Filed to: Solve Mac Problems • Proven solutions
Dec 02, 2019 I upgraded to macOS Catalina last week (10.15.1). Since then, my computer has crashed no less than three times with the exact same kernel panic, pointing out to something wrong with the graphics driver (com.apple.kext.AMDRadeonX4000). The usual trick of letting one minor version pass before upgrading did not work. Update 1: It's a widely reported.
Feb 29, 2020 The last 4 years were a disaster on the Mac side, trash can Mac Pro, skinny throttled mbp’s, Buggy OS releases (permanently deleting emails? Really Apple?) The optimist in me thinks that maybe they’re trying to find their way back, and the mbp 16 is a first, though unsteady step. Since the last update (2 or 3 days ago) my Mini has been hard-crashing (kernel panic, forcing me to shut down) at least once a day. I haven't had a hard-crash like this in probably a year or more. The last update included iTunes 10.2.1, Safari 5.0.4, and Java for Mac 10.6 Update 4.
Kernel Panic is probably one of the most fatal errors in Unix systems (like macOS) that makes the entire OS standstill. The error is often compared to a screen of death in other operating systems. Although it might seem like a complicated situation, you can try to fix the Kernel error on your Mac. In this post, we will let you know what is Kernel Panic error and how to fix it by following different tested approaches. Apart from that, we will also provide a stepwise solution to restore data from your Mac after a Kernel error recovery.
Part 1. What Is Kernel Panic?
Before we teach you how to fix Kernel Panic, it is important to cover the basics. For instance, you must be thinking what is Kernel Panic and the reasons behind it. As you know, an operating system consists of various kernels to run all kinds of processes. When a kernel is corrupted or damaged beyond the scope of repairing, it causes the Kernel Panic error on Mac. As a result, the following screen is displayed on Mac and we are asked to forcefully restart it.
There could be all kinds of reasons for causing the Kernel error on Mac, including the following:
- Mostly, the Kernel Panic error happens when the OS tries to access a piece of memory that is not available anymore.
- The situation also arises when the OS is overburdened by too many processes.
- A malware or a virus attack on your Mac can also cause this problem.
- A hardware related issue with the hard drive, RAM chip, or any other similar scenario.
- It can also happen when Mac tries to load drivers that are not compatible with it.
- If your system is running low on storage or resources
- It can also happen if you are running an outdated version of macOS on the system.
- Your macOS could be in a deadlock, resulting in the Kernel error.
- A faulty application or process can also end up in this fatal error.
Part 2. How to Fix Mac Kernel Panic Error
Since there are different reasons for causing a macOS Kernel issue, we need to look for various ways to fix it. You can try some of these suggestions for MacBook Pro Kernel Panic fix that works on every major macOS version as well.
1. Start Mac in Safe Boot mode
This is the safest and the easiest solution to fix Kernel Panic error on Mac. When your system would boot in the safe mode, it will only load the essential processes. This would not include any third-party communication, updates, additional processes, or even network kernels. Therefore, when the core macOS would be loaded, the operating system will get a chance to fix the faulty Mac kernel.
- Firstly, make sure that your Mac is turned off. If not, then long-press the Power button to switch it off.
- Once your Mac is powered off, wait for a while and turn it on again. This time, hold the Shift key while it boots.
- This will automatically turn your Mac in the safe mode. You can just log-in to the respective user account to access your system.
2. View Kernel Panic logs
To help users diagnose any major issue related to their operating system, Mac provides a detailed Kernel Panic log. This would have information about any critical kernel or process related to Mac. You can easily access the log file to examine what could have caused the problem in the first place. After identifying a faulty kernel, you can just update or remove the application Microsoft internet controls vba mac. associated with it. Here’s how you can access the Kernel panic log on Mac.
- Firstly, start your Mac to access the Kernel log. If you want, you can start it in the safe mode as well.
- On the Finder menu, click on Go > Go to Folder and enter the “/Library/Logs/DiagnosticReports” location on it.
- As you will press enter, Mac would open the Diagnostic Reports folder from where you can select the Finder Panic log.
- Once you double-click it, the log file would be opened with Console. Now, just identify the faulty kernel on your Mac and try to deal with its cause.
3. Software Troubleshooting
After accessing the Kernel Panic logs, you would be able to identify what could have caused the problem to start with. If you think that it is caused by a software-related issue, then consider following these suggestions.
• Software Update
If your Mac is running on old or outdated software, then you should try to update it to fix Kernel error. To do this, just go to the Apple logo on the top-left corner and click on “System Preferences”. Open the Software Update component to look for the available macOS update for your system. By following a simple click-through process, you can update macOS and fix MacBook kernel panic problem.
• Reinstall macOS
Chances are that the existing version of macOS would have been corrupted as well. In order to fix this, you can simply reinstall macOS on your system. To do this, restart Mac and keep pressing the Command + R keys at the same time during its startup. This will display the macOS Utilities window on the screen. Click on the “Reinstall macOS” option from here and start the installation.
• Clean install macOS
Sometimes, even after reinstalling macOS, users encounter the Kernel crash. To completely avoid this, you can do a clean install of the OS. This means, you have to first erase all the existing data on the macOS drive and again install the operating system on it from the scratch. Needless to say, since it will erase all the saved data on the selected drive, it should be your last resort.
Firstly, start your Mac in the Recovery Mode by pressing Command + R keys simultaneously. Go to the Disk Utility option and select the drive where macOS is installed.
Click on the “Erase” button and confirm your choice to format the drive. Wait for a while and restart your Mac in the Recovery Mode. Again, choose to reinstall macOS to fix this problem.
4. Hardware Troubleshooting
While the chances are bleak, sometimes a hardware-related issue can also be a reason for macOS kernel Panic issue as well. You can try to resolve this by following either of these solutions.
Let's hope the upcoming Skype for Business for MacOS is everything we expected and more ). Microsoft lync wants to use the oc_keycontainer mac issue 2016. You'll see a few files called:OCKeyContainer useraddress. For example: OCKeyContainerAndyPandy@Contoso.comSimply delete them. Usual user password doesn't work. It was putting up a prompt saying:Microsoft Lync wants to the 'OCKeyContainer useraddress' keychainand asking for a password.

• Check peripheral devices
Since peripheral devices can easily corrupt your Mac, you should remove them and restart your Mac afterward. To do this, just carefully eject any peripheral device like printer, USB drive, SD card, etc. You can even remove any third-party USB mouse or keyboard that you are using. Afterward, restart your Mac and check if the Kernel Panic error occurs or not.
• Check and repair the disk
Last, but most importantly, there could be a problem with Mac’s disk as well. Before you check for any physical damage, try to repair it using Disk Utility. Simply restart Mac in the Recovery Mode and click on the “Disk Utility” section from macOS Utilities. You can also access it from Mac’s Finder > Applications > Utilities > Disk Utility. Select the disk you think is faulty and click on the “First Aid” option on the toolbar to repair it.
If this won’t fix the problem, then you can dismantle your Mac and check for any physical damage on the disk.
Part 3. How to Recover Data After Kernel Panic on Mac?
Too often, the Kernel Panic issue leads to the unwanted loss of data on Mac. If you have also suffered from the same, then take the assistance of Recoverit Data Recovery Mac. It is the latest release of the professional data recovery application developed by Wondershare. A user-friendly and sophisticated recovery tool, it supports all kinds of data loss scenarios.

If you’re reading this, there’s a good chance your Mac just suffered a kernel panic and you’re searching for what to do next. We’ve got the answer, and it’s simple: Don’t panic. Instead, take a deep breath, relax, and know that almost all kernel panics are transitory; events that aren’t likely to keep repeating. You don’t need to live in fear that in the next minute, your Mac will crash once again.
On the downside, you likely lost any unsaved work up to the point of the kernel panic. There’s a remote chance that some work may have been saved in the last Time Machine backup.
What a Kernel Panic Is
In UNIX-based operating systems, such as OS X and macOS, a panic is an unrecoverable error that was detected by the operating system kernel. It’s unrecoverable because the kernel, the basic heart of the operating system, can’t figure out how to get back on track. In essence, it’s lost, and not sure how it got here. When this occurs, the kernel runs the panic function code that tells it what to do in these situations. Unfortunately, about the best the kernel can do once it runs the panic code is collect some data about the current condition of the processors, and what processes were running, and then halt or restart your Mac.
Microsoft
(The older style kernel panic text stayed until you restarted your Mac.)
In OS X Lion and earlier, a panic resulted in the screen dimming and a message in multiple languages that said: “You need to restart your computer. Hold down the Power button for several seconds or press the restart button.” The message was white text on a black background.
OS X Mountain Lion changed the look and sequence by automatically restarting the Mac, and then displaying a text message similar to the one above, but with black text on a gray background.
What a Kernel Panic Is Not
Kernel panics are sometimes confused with application crashes, startup problems, or sustained beach balls. The big difference is that with a kernel panic, your Mac will display the kernel panic message as well as halt or restart on its own.
Check for Recurring Kernel Panics
It’s a bit more difficult in the older versions of OS X to discover if the panic will recur; that’s because you really need to have the same conditions in place: the same apps running, and the same background processes; you also need to perform the same task that precipitated the panic, such as saving a file, loading a web page, or launching an app.
(Selecting Open will launch all the apps that were running when your Mac crashed.)
With OS X Mountain Lion and later, your Mac saves the log of which apps and process were running, and will offer to reopen them when it restarts after a kernel panic. Simply click the Open button on the “You shut down your computer because of a problem.” dialog box when it’s presented during the login process.
Once your Mac has finished launching all the apps and processes, you should attempt to perform the same tasks you were involved in when the panic originally occurred. If there’s no panic after a reasonable amount of time, it’s probably not worth further troubleshooting attempts, and can just be chalked up to gremlins and ghosts.
Troubleshooting Recurring Kernel Panics
If, on the other hand, a kernel panic occurs soon after you click the Open button in the dialog box, you likely have a problem you need to track down.
One of the options in the “Your computer was restarted because of a problem” dialog box is “More Info.” Pressing this button will cause the dialog box to expand and display the panic report, a detailed look at what occurred at the time of the panic.
(You can view the panic report, which includes details about the kernel panic.)
Don’t worry if you already dismissed the dialog box; you can view the panic log with the Console app, located at:
/Applications/Utilities/
Simply launch the Console app, then in the sidebar, select the System Reports item, and then select the Kernel Panic item (the actual name will include the terms kernel and panic, but it will also have the date and the name of your Mac in the title).
(The panic report includes the calling app that was likely involved in the kernel panic, as well as active kernel extensions.)
Reading the Panic Report
The panic report includes the memory address and, in most cases, the name of the process that called for the panic function to be invoked. The calling process may be helpful, but it doesn’t always indicate what actually caused the event that led up to the panic; only the last process in the chain of events.
Other important information in the panic report is the list of loaded kexts as well as the last loaded kext. Kexts are extensions to the kernel that can be used to add functionality to the operating system. Apple provides many different kexts, but so do some third-party developers. If the last loaded kext was from, say, a third-party system utility you installed, that may be a good indication of what caused the panic, or at least, what was involved in the panic.
Peripherals
Kernel panics can be caused by hardware as well as software. Checking for a hardware cause for a panic is fairly straightforward. Start by isolating all external peripherals you have connected to your Mac, except for the keyboard and mouse or trackpad.
Start your Mac in Safe Mode by holding down the shift key and pressing the power button. Keep pressing the shift key until your Mac finishes starting up.
If your Mac is able to start in Safe Mode, then its basic hardware is in good shape. Restart your Mac to leave Safe Mode. Once back in normal mode, try running a few apps. If everything is OK, then the kernel panic was likely a transitory event caused by an app or process in combination with another app, process, or device not getting along; it may also have been caused in part by one of the peripheral items you disconnected.
Shut down your Mac, reconnect a peripheral, and then restart your Mac. Try opening the same apps that were in use at the time of the panic. If everything seems OK, then shut down and connect the next peripheral. Continue the connect-and-test process until all your devices are reconnected.
If you find a device that causes a panic, check for updates to the device’s drivers, as well as updates to any apps that are involved.
Apps and Software
Just like you did for checking the Mac’s hardware, you can use Safe Mode to test for apps and other software that are causing the kernel panic. Safe Mode keeps startup items from being loaded, as well as third-party kexts and fonts (other than those used by the system). Once you’re running in Safe Mode, you can disable startup items by using the Users & Groups preference pane.
After you disable startup items, use Font Book to validate your installed fonts. If any fonts come up with errors, use Font Book to disable the indicated fonts.
Go ahead and restart normally. If no kernel panic occurs, add one of the startup items back, then restart. Repeat and test each startup item until all have been restored.
Internal Hardware
Your Mac’s internal hardware, including RAM and storage drives, can be a source of kernel panics. You can use Apple diagnostic routines to test your Mac. You’ll find instructions for how to do this in the Rocket Yard Guide: How to Run and Interpret Your Mac’s Built-in Diagnostic Routines.

Reinstall the Mac OS
Because the OS can also be a source for kernel panics, usually due to corrupt system files, if you can’t resolve the panics, our last tip is to reinstall the OS. You can use the Recovery HD partition to perform the reinstall. Reinstalling the OS should replace any corrupt system files, while retaining user data and apps.
