The report shows that the carbon black extension is still loaded and active.

Perhaps it is being loaded from a different directory than you expect, but there it is in the report, as the first listed "loaded kext"

Like many so-called anti-Virus apps. when it finds something it does not like, it causes a reference to an illegal memory address which causes the indicated, kernel panic, page fault, and the Kernel-Task (that it modified) takes the blame.

since you did the last update with anti-virus software in place, it is possible that all the components did not get installed properly -- your anti-Virus might have been "protecting" you.

You can re-install MacOS in-place, right over the same version. By design, this does not eliminate any User files or added Applications. But it is always prudent to have a backup before you begin any operation that will re-write over 350,000 files.

How to reinstall macOS from macOS Recovery - Apple Support

Hi,

Page Fault tends to be RAM related issue. Try to run Apple Diagnostics if it's caused by hardware related issue.

 menu > About This Mac > (system Report) > ...

Scroll down the sidebar.

under "Software" in the sidebar, find the heading "Extensions".

Click on it and wait up to several minutes for it to produce its report.

Stretch the window wide enough to read the "Obtained from" heading, and click on it to sort by "obtained from" in down order:

select the 'not-obtained from Apple' extension in question.

look in the list below for the heading: Location, about eighth item down in the text for that extension.

That is the directory/name on your Mac where the extension resides.

in my example, the directory is /Library/Extensions and the filename is 'hp_io_enabler_compound'

Copy the directory EXCEPT the last part, after the last / which is the filename

Finder > Go Menu > go to Folder ...

... paste the string and press return to get directly to the directory where the extension is located.

Drag the extension to the Trash (you can not Empty trash yet, it is still part of running MacOS)

Restart your Mac. [when it starts up, the Trashed extension will not become part of MacOS, and the Trash can be emptied.]

The Catalina Upgrade to 10.15.4 was enormous. Many Users run anti-Virus software, and many users are now having issue with the upgrade. So far only a correlation, and not a proven cause-and-effect.

You can assure yourself that your MacOS is "pure" by doing a re-install-in-place, right over your existing version. This is a common debugging technique, and if you contact support as suggested, this will be one of the first things they will ask you to do.

Hi,

kexts are located at /Library/Extensions/.

In Finder Go menu, Go to ... type /Library/Extensions/ then click Go.

Delete third party kexts and see if still kernel panic occurs.

while you are up, you should also move Norton and Symantec to the Trash. SymIPS is a Symantec extension that does not belong here.. acsock is a Cisco add-on, and finding it here is also dodgy.

Most of the rest are Drivers for Apple-Approved hardware that you could add. that is what is supposed to be in this folder.

When you Restart, the ones you moved to the Trash will not be included in MacOS. They will also no longer be marked as "in-use" and the Trash can be emptied after that.

If you remove (and do not put back) all graphics extensions, basic screen-drawing will still work, but you get no graphics acceleration. Screen drawing may be slow, and things may appear to be drawn and then re-drawn slightly differently. This is exactly the conditions that are forced by invoking "Safe Mode".

MacOS kernel does not panic in this fashion.

But you are not running MacOS kernel, as you have modified it with this invasive extension:

loaded kexts:

com.carbonblack.defense.kext 3.3.4fc6

this is not something that should be running on your already well-protected Macintosh computer. If you want to reduce the panics, remove it and leave it out permanently.

One trouble is, when you have a panic with third-party extension present, it gives Apple the excuse to say, "not me, its that third-party extension!".

The bad news is that now that extension is gone, you do indeed have a kernel panic in the graphics drivers with NO third-party extensions present.

I have a MacBok Pro (15" inch, 2017) and have been getting panic errors at night and the computer reboots.

I worked with the Apple tech and we created a new partition with nothing in it, but it still crashes. No icloud, software, only base image. It has already been in the shop 4 times now. Twice motherboard and recently battery. The panics have only been happening the last few weeks or so. Computer has never been as fast as a expected. In fact my old 2012 Macbook with Core 2 Duo and reg HD is faster. :(

Here is the latest panic error. I have a fresh image and reset SMC, etc.
