Kernel extensions show as directories

I was looking at the AMD and the Nvidia kernel extensions in /System/Library/Extensions to see if there was any info on the supported graphics cards in the Mavericks version of these files and I noticed something odd.
About 2/3 of the .kext files are presenting as directories.
For the few .kext files I did look at all I did was right click on the file and select "show package contents". Nothing was edited, or even opened in an editor. I do understand that .kes\xt files are basicly directories that are packaged up in a specific way.
Here is a snipet of what I am seeing...
I don't thing I even looked at any of the .kext files that are now showing as directories. I'm not sure if this will cause a problem on reboot or not.
Has anyone seen this issue before? Is this a finder problem?
Thanks,
James "Zeke" Dehnert

Everything in that folder should be a bundle -- that is, a folder that looks like a file in the Finder. If some of the items have lost that attribute, then your installation is corrupt and you should reinstall. You should also get rid of any third-party "utilities" that could have caused the damage.
Your screenshot doesn't show anything abnormal.

How to remove Kernel extensions, Slow Restart 10.7.5, Should I really upgrade to 10.9?

Hello everyone, after spending a few days reading various posts about similar topics, here is a breakdown of my question:
(I made a Time Machine backup on an external HD, even though EtreCheck says "Not Configured")
1: I used EtreCheck to diagnose my laptop, and I do not know how to locate the Kernel Extensions in the computer to eliminate them, or "solve" them. Can I find them with Finder? If so, do I just delete the files? How else can I pinpoint the issues EtreCheck shows me?
2: I am experiencing the "15 second waiting period" with the gray spining wheel when I restart, which only started happening about three weeks ago.
3: After multiple attempts, it seems that Mavericks 10.9 is finally downloading from the App Store, but I would rather not upgrade if I don't need to, since 10.7.5 has been working well until now.
MAINLY, this is important to me since I am using Abelton Live 9 with a new 64-bit Saffire Pro-14 firewire audio interface, and it has started clicking during playback, which cannot be solved with buffering/latency fixes. This is the main reason I got this laptop (for audio production) and I want to make sure it continues to function at the highest level for that purpose.
To be clear, I have not experienced a "kernel panic" that requires me to shut down... I am simply trying to maintain my system for optimal performance by deleting problem files.
Thanks to anyone who can give me some basic daemon/kernel hunting instructions.
Here is the EtreCheck report:

OS X upgrades don't cause problems, they reveal them. Every OS X upgrade since at least Jaguar has elicited complaints ranging from crashes, slowdowns, reduced battery life, everything short of an outbreak of hives. Most problems reported on this site are directly attributable to incompatible system modifications and poorly written or otherwise ill-conceived utilities. They exist in roughly the same proportion that have existed with every OS X upgrade since Jaguar, at least. Apple has no way to fix problems caused by software they did not develop and cannot control.
In your case, one definitely problematic system modification is the PACE anti-piracy app that does not appear to have been updated since Snow Leopard. I do not know what software you have that may require it, but it should either be updated or uninstalled before upgrading to Mavericks.
There are others that could be a concern including a launch daemon curiously named "com.hidden.deamon.plist". Well-written software should not be attempting to hide anything, but perhaps that was just an unfortunately chosen name. (Edit to add: read http://hiddenapp.com/support/installation/how-uninstall/ - it doesn't appear to have been updated for Mavericks either.)
If your boot time is excessive then an impending hard disk failure may be the cause. You must have a backup strategy, and rule out hardware failure as the possible cause of that symptom. If you have a backup strategy, then upgrading to Mavericks carries no risk whatsoever. If you don't like Mavericks, you can always restore your system from its backup. Merely having a backup often seems to preclude the need for it.
I upgraded many portable and desktop Macs of various ages and configurations. In every case not only was the upgrade completely uneventful, every Mac enjoyed quantifiable performance improvements. None of them have the notoriously problematic software or incompatible hardware modifications that seem to have caused others misery though. In broad terms those can be categorized as third party "anti-virus" or "security" junk, "cleaning" or "optimizing" utilities, any number of invasive Google services including Chrome, and similarly ill-conceived system hacks.
In your case the only potential concern with which I am familiar is PACE. Since I have no way of knowing what software you use I can only speculate what may require it, but I seem to recall PACE is or was used by Avid Pro Tools. Does that help?

How do I remove an unnecessary kernel extension?

I ran an Etre Check this morning and found I have a kernel extension that I do not need. It has likely been on my computer since I bought it new and had my old Windows files migrated to my iMac by the Apple Store. I do not now, nor have I ever had, a Kodak printer, so I think this just got loaded with Kodak Gallery when I had a Kodak camera. All my photos were migrated to iPhoto and Kodak Gallery does not exist on my mac. It shows up as a kernel extension on the Etre Check report but is listed as an (unloaded) Application in my System files. I tried to drag it from the System files to Trash but that resulted in everything listed below it being highlighted which I certainly didn't want. It does not show up under Applications in Finder. Here is how it shows up in the report, which was otherwise normal. Thanks for any help with this.
Kernel Extensions: ℹ️

Thanks for your response. I couldn't delete it in the Systems files that way. I finally found it under Applications Support in Finder and was able to drag it to Trash.

Unable to install the Novell File Upload extension to upload directories

Using Firefox 9.0.1 on Windows 7 I'm unable to install the Novell File
Upload extension to upload directories.
As per the pop-up help page, I've added
extensions.install.requireBuiltInCerts in about:config and set it to
false but that has made no difference, even after restarting the browser.
I've also tried this with Firefox 9.0.1 on Mac OS X Snow Leopard
(10.6.8) - unsupported I know - with the same result.
Do I really have to use Internet Explorer? Urgh!

So, with Firefox, first hitting http://<server>/zenworks/ after install
displays
--begin--
This Connection is Untrusted
You have asked Firefox to connect securely to <server>, but we can't
confirm that your connection is secure.
Normally, when you try to connect securely, sites will present trusted
identification to prove that you are going to the right place. However,
this site's identity can't be verified.
What Should I Do?
If you usually connect to this site without problems, this error could
mean that someone is trying to impersonate the site, and you shouldn't
continue.
[Get me out of here!]
> Technical Details
> I Understand the Risks
---end---
so I click "I Understand the Risks", [Add Exception...] then [Confirm
Security Exception] at which point http://<server>/zenworks/ correctly
displays and I can log in. Checking Tools | Options | [View
Certificates] shows an (Unknown) server certificate for <server> with a
Permanent lifetime.
Is that what you mean by trusting the ZCM CA?
Perhaps this is why Firefox 9.x is not a supported browser though I
thought that was more to do with Mozilla treating major version numbers
as minor ones? Gee if only Firefox hadn't automatically upgraded itself
from 8.x to 9.x!
Thanks.

Kernel extension problem after upgrade form 10.5.8 to 10.7

Dear Experts,
I was trying to prepare t show my students in the next term building MAC OS X "kernrl modules"
next to Linux kernel modules in the same way via compiling directly form source
While using MAC OS 10.5.8 then evereything in the
http://unixjunkie.blogspot.com/2006/12/kernel-extension-by-hand.html
worked well
But was to buy 10.6.3 in the last available MAC BOX Set in our conutry yesterday Using this Ibundlw I was to upgrade to the MAC OS X 10.7 Lion. Then I was not able to insert this kerne; extenion and I was unable to find any source about it except that since 10.6 there were changes in the system of producing kernel extension with no details.
My outputs
sudo kextload -verbose 6 ./MojKext.kext/
Password:
Kext user-space log filter changed from 0xff2 to 0xfff.
Kext kernel-space log filter changed from 0xff2 to 0xfff.

/Users/peto/Documents/kext2/MojKext.kext failed to load - (libkern/kext) link error; check the system/kernel logs for errors or try kextutil(8).
sudo kextutil -nt MojKext.kext
No kernel file specified; using running kernel for linking.
kxld[com.apple.filesystems.MojKext]: The Mach-O filetype 0x1 is not supported on the target architecture.
Link failed (error code 5).
Check library declarations for your kext with kextlibs(8).
sudo kextlibs MojKext.kext -all-symbols
For all architectures:
No libraries found.
For x86_64:
0 symbol found in one library kext each.
This is beacuse I was removed printf from the source.
Is there anybody who is able to get me some informations/documentation, how to build kernel extensions,please?
Thank you for any help
I look forward hearing from you
Yours faitfully
Peter Fodrek

I think at a minimum you'll need to get Xcode 4.1 for use with Lion. It's free from the App Store.
And Kappy is right, the developer forums are more likely to be of help.

Kernel extension did NOT load

After reformatting my hard drive and reinstalling 9.2.2 and all necessary upgrades to reach 10.4.11, I can no longer see my Aurora Igniter capture card (which worked fine before the reformat). When I reboot using 9.2.2, the card IS seen and works flawlessly. But when I restart in 10.4.11, it's gone. When I open Ignition in System Preferences, I get the message: "The kernel extension igniter.kext did not load!" and it says no driver was installed. I see a driver in my OS 9 System folder extensions folder, but a search of my hard drive shows no such .kext file exists anywhere. Any ideas? I know Aurora is no longer in business but I'm trying not to have to replace my capture card and breakout box. Also, I'm using the latest driver for the card.
Thanks!

Everything is the same as before, except that I installed FCP Studio to replace 4.5 Otherwise, it's the same OS, same QT... unfortunately, although I backed up most things, I failed to back up my OS 9 system folder. I do, however, have a copy of the original installation log of the Aurora card back in 2002, for what it's worth. This is, of course, the install under 9.2.2, which is still working.

The first thing to do would be to boot from the Install & Restore disc that came with your machine by:
1. Inserting the disc, pressing the power button, and immediately after the startup chime, press and hold the C key until you see the spinning gear icon appear on the grey splash screen.
2. After the machine has booted, pick your language, and when the Installer window appears, do not press Continue, but go to the Utilities menu in the menubar and open Disk Utility.
3. In Disk Utility, choose your normal startup volume in the pane on the left and then click Repair Disk. If any errors show in the window, run Repair Disk again until you see 'The volume appears to be OK' in green.
4. Quit Disk Utility, quit the installer and attempt to restart into your regular startup volume.

Refurbished MacBook Air won't boot up. First time turning on and I'm met with Kernel Extension problems. Help?

I turn on the power button, and then it tells me a load of data. I cannot load up my MacBook, to even get to a set up page. I have only had it put of the box 10 minutes and turned it on once haha.
It shows the apple logo, an then brings up the data, where it says things like
"Panic(cpu 0 caller -loads of numbers-) "pthread Kernel extension not loaded (function table is NULL)
BSD process name corresponding to current thread: kernel_task
Mac OS Version:
Not set yet
Darwin Kernel version 13.0.0
What could this be? Apple support is unavailable to call until Tuesday apparently
Please help. I just want to use my new MacBook

Felix, there is nothing you should do about this other than to return it to Apple for a refund, and purchase another. I wouldn't think twice about it.

Adobe extension show in the Extension Manager and are enabled but do not appear at all in Photoshop CC 2014.

Adobe extensions show in the Extension Manager and are enabled but do not appear at all in Photoshop CC 2014. Third party extensions do show up and can be used. All extensions are available in and can be used Photoshop CC. I have reinstalled CC and Extension Manager to the most recent releases and the Adobe extensions are still not available in Photoshop CC 2014. What should I do now?

Flash based extensions are not supported by PS CC 2014 anymore. Please refer to http://blogs.adobe.com/photoshopdotcom/2014/04/photoshop-spring-cleaning.html, http://blogs.adobe.com/jkost/2014/06/installing-the-2014-release-of-creative-cloud.html
And http://blogs.adobe.com/crawlspace/2014/06/2014-release-of-photoshop-cc-faq.html#plugins (scroll down to "Why don’t my 3rd Panels show up in the 2014 release of Photoshop CC? What happened to Oil Paint, Mini-Bridge & Kuler?”)
There is a new Kuler HTML5 panel available on Add Ons: http://adobe.ly/UgxQSN
Adobe is working on HTML based version of Adobe Watermark, eMailer, etc.
If some extensions are must have for you, you have to continue to use PS CC until HTML based counterparts become available.

Is it possible to use C++ in a Kernel Extension?

In the "Kernel Extension Programming Topics" document there are two examples of kernel extensions - HelloKernel and Hello I/O Kit.
The Hello IO Kit is created as an I/O Kit Driver project and HelloKernel as a kext project.
Hello I/0 Kit has C++ classes in it whereas HelloKernel is just C.
Is it possible to use C++ in a kext project? If so what header files or bundles must be included to make it possible?
My aim is to develop an NKE (which I presume has to be created as a kext project) and I would rather implement it it using classes than using just C.

hotcheese wrote:
Was it pre-Snow Leopard?
Yes
I've just seen this following text from the Kernel release notes for Snow Leopard, would this make a difference? ( I notice it mentions I/O however, why is C++ allowed in I/O kexts but not in others?)
*Mixed C/C++ Kexts*
Mac OS X Snow Leopard features support for kexts that use both C and C++ code. On prior
releases of Mac OS X, making use of Libkern C++ classes in a generic (C-based) kext was a
risky proposition, since the I/O Kit auto-unloading mechanism destroyed any kext
referencing such classes if there were no instances of them. Apart from that, even if non-
Libkern C++ was used, the stub routine invoked at unload called the kext’s static C++
destructors before the kext’s stop routine, and when the kext was auto-unloaded the stop
routine wasn’t invoked at all.
Snow Leopard corrects these issues by:
Marking only kexts that define subclasses of IOService for auto-unload. Non-I/O Kit
kexts loaded on Snow Leopard can safely use and subclass Libkern C++ classes.
Altering the stub unload routine to call the kext’s stop routine first, then the kext’s
static C++ destructors. Important: To gain this behavior you must build your kext to
be targeted against Snow Leopard, as the stub routine is built into the kext.
Always unloading a kext by calling both the stop routine and then the C++ static
destructors, regardless of kext type (generic or I/O Kit).
That is very interesting. I suggest you post your question on Apple's Darwin kernel mailing list. I have seen postings there that both echo what I told you and claim that you can make C++ work fine. It is highly likely that I just need more experience writing kernel code (and a better project idea). I would like to know the answer to this question myself. It doesn't seem as cut and dried anymore.

After Loading Lion I now get 5 windows w/ a graphic of a Red Stop sign with an ! mark and the following text message: "DAVE Networking Dave kernel extensions could not be loaded! Error 71 - Too many levels of remote in path."

After Loading Lion I now get 5 windows w/ a graphic of a Red Stop sign with an ! mark and the following text message:
"DAVE Networking
Dave kernel extensions could not be loaded! Error
71 - Too many levels of remote in path."
I have uninstalled DAVE and used Clean App to remove trace elements of program, however I still get the message and am unable to eliminate the error messages. When I click OK the message goes away briefly and then comes back up.
Any solutions would be great.

Dave,
Thanks....What I did was load the free eval version of Dave 9.0 and then used the uninstaller which must have deleted the kernel giving me the problem.
Thanks for the response.

You have the MacBookPro6,2—the Edsel of Macs. It may have the logic-board defect that was covered by this recall.
Make a "Genius" appointment at an Apple Store, or go to another authorized service provider, to have the machine tested. The routine hardware diagnostics used by service providers do not detect the fault. There is a specific test for this issue that Apple calls "VST" (for "Video Switching Test.") Ask for it. A "Failed" result means that the fault is present. However, according to reports, some units may pass the test, and yet still be deemed eligible for repair under the program. Your experience may vary.
Print the first page of the panic report, if any, and the support page linked above, and bring them with you.
Note that the recall only applies within three years of purchase. After that, Apple may refuse the service. In that case, you may be quoted a price of about $300 (in the U.S.) for a "depot repair," which involves shipping the unit to a central repair facility and takes about two weeks. For that flat fee, anything found wrong with it should be fixed, not just the logic board.
The model was discontinued on February 24, 2011, so the recall has nominally ended. Some units may have been sold after that date by Apple as refurbished, or by resellers as new, and they might still be covered.
Some owners report that their unit was repaired under the program after the deadline had passed. Others report that the repair was covered by the extended warranty from a credit-card issuer. Again, your experience may vary.
Sometimes the replacement part is also defective, so be prepared for that possibility. If you decide to pay for a new logic board, test thoroughly during the 90-day warranty period on the repair. Some owners have reported that they went through as many as three replacement boards before getting one that worked.
If it's too late for your unit to be repaired free of charge, and you don't want to pay for the service, you may (or may not) be able to stop the panics by disabling automatic graphics switching. To use the discrete graphics processor, you'll need a third-party utility to switch to it manually.
Often the problems start after an OS upgrade. If the upgrade was recent, and you have backups, then you can revert to a previous OS X version.
If you're dissatisfied with Apple's response, please keep in mind that no one here represents the company or can help with customer-service issues.
Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
*An SSD doesn't need to be zeroed.

Confused about kernel extensions

I've learned two things about kernel extensions from Google searches:
1. Kernel extensions are stored in System/Library/Extensions
2. You can list all Apple extensions with the Terminal command kextstat and all third party extensions with the command kextstat | grep -v com.apple.
But something doesn't add up: the files listed by the kextstat command all begin with "com.apple". No files in System/Library/Extensions begin with "com.apple". In fact, none of the kernel extensions listed by the kextstat command seem to reside in System/Library/Extensions. So where are they?

I have the following result with the terminal command kextstat
Index Refs Address            Size       Wired      Name (Version) <Linked Against>
111    0 0xffffff7f80b71000 0x5000     0x5000     com.Cycling74.driver.Soundflower (1.6.6) <101 5 4 3>

I found the Soundflower driver in /System/Library/Extensions/
But ccould not find the other one BRESINKx86Monitoring anywhere .
where is it hidden?

How do I uninstall a kernel extension

I recvently installed the drivers for a USB graphics tablet.
But it didn't work as well as I'd like so I no loner use the device.
There are no un-install instructions with the device, and no un-install instructions on the manufacturers website.
When I email them they just say they don't support Mac OS X despite the driver being in the box!!!
Now that I've unplugged the device, my system log is full of dozens and dozens of these messages....
Jan 13 12:53:48 localhost kernel[0]: IOUSBInterface: family specific matching fails
Jan 13 12:53:48 localhost kernel[0]: IOUSBInterface: family specific matching fails
Jan 13 12:53:48 localhost kernel[0]: IOUSBInterface: family specific matching fails
Everytime I boot I see dozens of these messages repeated over and over.
So how can I un-install the driver for this device?

Without knowing exactly what was installed...
Kernel extensions can be found in /System/Library/Extensions
There should be a .kext bundle corresponding to the driver you installed. Delete that to uninstall it. Be very careful not to delete the wrong one though!

How to get rid of kernel extension under maverick

Hello,
this kernel extension (com.globaldelight.driver.BoomDevice (1.1 - SDK 10.5)) seems to be causing kernel panic and shuts down my computer randomly. Could you please explain how to unsintall it
Thank you in advance

Any third-party software that doesn't install by drag-and-drop into the Applications folder, and uninstall by drag-and-drop to the Trash, is a system modification.
Whenever you remove system modifications, they must be removed completely, and the only way to do that is to use the uninstallation tool, if any, provided by the developers, or to follow their instructions. If the software has been incompletely removed, you may have to re-download or even reinstall it in order to finish the job.
I never install system modifications myself, and (unless otherwise specified in this comment) I don't know how to uninstall them. You'll have to do your own research to find that information.
Here are some general guidelines to get you started. Suppose you want to remove something called “BrickMyMac” (a hypothetical example.) First, consult the product's Help menu, if there is one, for instructions. Finding none there, look on the developer's website, say www.brickmymac.com. (That may not be the actual name of the site; if necessary, search the Web for the product name.) If you don’t find anything on the website or in your search, contact the developer. While you're waiting for a response, download BrickMyMac.dmg and open it. There may be an application in there such as “Uninstall BrickMyMac.” If not, open “BrickMyMac.pkg” and look for an Uninstall button. The uninstaller might also be accessed by clicking the Customize button, if there is one.
Back up all data before making any changes.
You will generally have to reboot in order to complete an uninstallation. Until you do that, the uninstallation may have no effect, or unpredictable effects.
If you can’t remove software in any other way, you’ll have to erase and install OS X. Never install any third-party software unless you're sure you know how to uninstall it; otherwise you may create problems that are very hard to solve.
WARNING: Trying to remove complex system modifications by hunting for files by name often will not work and may make the problem worse. The same goes for "utilities" such as "AppCleaner" and the like that purport to remove software.
