System extension cannot be used, now no AirPort Card Installed?!?!?!?!

I have had my MBP for some time now and the other day it went into a kernel panic and after having to go through all the processes to recover it including restoring from the time capsule so that it doesn't take over 10 mins to start up an error message came up saying;
"*System extension cannot be used*"
"the system extension '/System/Library/Extensions/IO80211Family.kext/Contents/PlugIns/AppleAirPortBrc m4311.kext' was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update"
Now i cant use my airport card at all, it says that there is no airport card installed and I have spent hours on the phone to apple, done the option + command + r + p thing and had to restore my whole system off my TC with the backup disks and all.
Plz plz plz plz help, i just want it back the way it was, this is so annoying

I had the same problem. It happened to me after I updated to 10.5.6. I didn't notice the problem until I rebooted a few days later. I reinstalled the system from disk and then realized that even though it took almost an hour it didn't really install anything. So I deleted the whole /System/Library/Extensions/IO80211Family.kext and reinstalled the system again. This time it worked

Now what when i'm told: "System extension cannot be used"

I was installing Propellerheads Record ( package installation ) when this message pops up near the end of installation:
System extension cannot be used: The system extension "/System/Libraryu/Extensions/CmUSBMassStorage.kext" was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update.
And then the installer went on and said installation was a success giving it the green check mark.
I have no clue who the vendor was.
How do fix it?
Is it related somehow to my iMac 306 and it TB harddrive?

Sounds like a typo was made by the installer.
There is /System/Library/Extensions/ but no /System/Libraryu/Extensions/
The 'u' after Library may either indicate an accented symbol
The mass storage kernele extention for USB would be for devices that store data that are connected to your USB port. Now, I don't have a registration for their support website, however, they do have a Snow Leopard comaptibility statement if you do register. I would register, and see what it has to say, before you attempt any further installs.
Aside from my typing mistake i should have said that this was a demo version to give me a taste before i buy.
I've sent propellerheads a question thru their web page.

"System extension cannot be used". And now..?

This is not an HP question...
I recently reinstalled a mini with 10.5.8 and then Snow Leopard. After installing the HP driver for their ScanJet 3670 the installation proceeded to very near the end and then threw up the message:
"System extension cannot be used
The system extension “/System/Library/Extensions/hpPlugInInit.kext” was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update."
...and then the installation ending with "The installation was successful.", which it wasn't. Following others' advice, I deleted the 'hpPlugInInit.kext' entity and reinstalled the software. Same thing happened again.
I appreciate that this looks like HP's software failure, but would like some views on whether this is, perhaps, more related to the OS and its setup. I don't know what the source of the offending kext is or whether it might be Rosetta-related - the 3670 is not supported under Lion (why it's installed on a SL machine and not my Lion box) and wonder whether this is just old code that is playing up.
Any ideas or solutions, please?

That will happen if the kext is not owned by root and/or doesn't pass code signing verification. If an installer was interrupted then it probably didn't finish its job and you'll need to trash that bundle.

System extension cannot be used - on startup?

Recently, I had to repair permissions after a error cause me not to be able to login. I did a startup from the disc and got in, but now these error messages come up;
System extension cannot be used
"/System/Library/Extensions/SymIPS.kext" was installed improperly and cannont be used. Please reinstalling it, or contact the vendor for an update... and;
"/System/Library/Extensions/SymIInternetSecurity.kext" was installed improperly and cannont be used. Please reinstalling it, or contact the vendor for an update... and;

"/System/Library/Extensions/IO80211Family.kext" was installed improperly and cannont be used. Please reinstalling it, or contact the vendor for an update...
not to mention now it says I don't have airport card and the internet is running slower!
I have completed further repair disk permissions.
What can I do?
Thanks.

HI,

Is this the results of booting from your install disk and using Disk Utility to Verify the drive, or just repair permissions?

Modem: System Extension Cannot Be Used

I made an error attempting install the modem extension from my iMac into my iBook so I could connect at more than 28,800. Now I get the following message at startup: System Extension Cannot be Used. The system extension "/System/Library/Extensions/Applel2ModemFamily.Kext" was installed improperly and cannot be used. In Network Port Configurations, the modem is grayed out. I tried to reinstall OS 10.4.8, but problem remains.
Is there any way to reinstall just this one extension?
I saw mention of doing an Archive and reinstall of the OS in another post. If I do that, will I need to reinstall all other applications, such as Virtual PC. I don't want to risk making them all not work, but would like to get modem capacity back.
Currently I have dialup on my iMac being shared via Airport
iBookG4 Mac OS X (10.4.8) 1.42 Ghz, 1.5 Gig RAM

…will I need to reinstall all other applications, such as Virtual PC
No. See http://www.apple.com/support/tiger/install/ for details, especially the one about A&I.

System extension cannot be used --can anyone help ?

so i spotted that the system library as well as the home library had permissions blocked for the administrator, so i unlocked all enclosed items permissions.
i already had issues being brought to senior advisor attention over 1,5 years now, about hangs and freezes. mostly hangs.
no one so far has been able to fix them.
well now spotting these warnings, after i allowed all permissions inside both libraries, have warnings show up.
i gather these are not prepperly installed softwares, but i cant figure out what softwares they could be, so i can take care of it.
so 4 warnings shows up :
System extension cannot be used
The system extension “/System/Library/Extensions/System.kext/PlugIns/Unsupported.kext” was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update.

There isn't an "administrator" so who did you add and what permissions did you set.
In Get Info, they should be
system read & write
wheel read Only
everyone read only
The posix permissions, owner, and group should be
rwxr-xr-x root wheel
with ACE "group:everyone deny delete"
You may be able to recover by repairing permissions in Disk Utility, but you may have to reinstall the OS.

I have done permissions repair at least 10 times in a row and it still comes up with things to repair but is there another soloution?
Also, It says i have insufficient permissions to get onto my external HD now as well.
Anything will help...

I had the same problem. Then due to another unrelated problem I did a file system check in single user mode and this problem too went away. I am not sure if it will also work for you but no harm to try.
Shutdown, restart by pressing power button. As soon as you hear the chime, press cmd-s. After a while lot of text will roll down the screen, leave the keys. At the prompt, type fsck -fy. Note the space. then hit return. If at the end of the run you get something was repaired, then run it again till you get 'OK'. After that type reboot and you will boot into regular OS X. Then do whatever you did to get this message and see if it goes away.

What can I do?

You recently updated iTunes to v.11.4? This message has popped up on many a Mac screen when this version was first made available, because this kext was obviously faulty.
You should try to download iTunes 11.4 again from Apple's website: the new version bears the same name, but this kernel extension has been updated, and the issues it was causing are now a thing of the past.
Should solve your problem, too...

Changed Permission Settings: "System extension cannot be used"

I was having some weird problems with file sharing on my network recently, so I tried changing around some of the permissions on my drives to see if I could resolve it. For some reason I was getting messages saying I didn't have permission to copy files from one computer to another on my network. This seemed to come on randomly as we have been doing file transfers this way for quite some time now. I looked at our file sharing preferences in the System Preference's and added all 4 drives from my Mac Pro in there and made sure that my username had full read and write capabilities. I then tried logging into my Mac Pro from my iMac, just like I've done in the past, and I was still unable to copy the files. So I removed all the folders and turned off file sharing. I then clicked 'Get Info' for my main Macintosh HD and tried changing the permission settings there. I clicked the option to make my username the owner, and then I clicked 'Apply to enclosed items...' and this brought up a progress bar that I let go for about 10 minutes. Then I got a pop-up error message stating "System extension cannot be used" and had an extension path listed underneath, saying it was installed improperly and cannot be used. This happens an endless amount of times. It seems to be giving me this message for every single extension on the computer. If I hold down enter the pop-ups just keep coming with different extensions listed.
I hope someone with some insight on how permissions work in OS X Lion can give me some advice on how to resolve, and possible the correct way I should be setting up sharing if I've been doing wrong all this time. What strikes me as odd is that I never had any issues with sharing anything up until about a week or so ago, and I can't remember if there were any system updates that I installed that might have something to do with this.
Any help is much appreciated, thanks!

I had this problem recently in addition to my laptop getting stuck on the Apple logo and spinning icon. It took me a long to time to work through it so I thought I would share what I did to make it easier for others.
The best thing to do when having permission problems is to do a 'disk permissions repair'. You can do this using the disk utility app found in your applications/utilities folder. This will attempt to rewrite all the permissions that were incorrectly set. When it is doing this it is common to get a message saying 'ACL...found and not expected...' do not go and delete these files. Its normal for this correction process to take more than 30 minutes, for me it took an hour.
If this proccess doesnt work for you than you can also try a disk repair.
If you can't boot using the normal disk you can also access this program through the recovery boot (holding Command-R of Option at startup), through the safe mode (holding Shift on start up) or through a recovery CD. You can also boot in a terminal type mode but this is a last ditch effort as a misspelt command could do more damage. personally, because I do not know what the commands I am using actually mean, I would recommend talking to a person at apple then using this approach.
Hope this helps

"System extension cannot be used" after installing iTunes 11.4

Installing latest version of iTunes (11.4) today led to the following error message:
System extension cannot be used
The system extension “//System/Library/Extensions/AppleUSBEthernetHost.kext” was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update.
I'm able to use my USB drive for Time Machine, and that appears to be functioning ok. Why this error message? Anyone else had it? And what does it mean for the continued safe operation of my MacBook? Would be reassuring to know if this is happening for anybody else, and if anyone else has found it affecting them. (Other than the distraction of getting a worrying error message that I take time out to report?)
Thanks in advance.

the "//System/Library/Extensions/AppleUSBEthernetHost.kext can just be replaced to overcome the problem as indicated below. Mine was dated 2012 and after the latest iTunes update, stopped working. I noticed this as my personal hotspot connection between my MacBook Pro and my iPhone failed (I use the USB cable for this). To overcome the problem, first unlock the //System/Library/Extensions/AppleUSBEthernetHost.kext file, then drag it to the waste bin and empty the waste bin. Then download iTunes and reinstall-you don't have to remove anything-just reinstall. This will put back a newer //System/Library/Extensions/AppleUSBEthernetHost.kext file dated 2014. After this, restart your computer and it should now work. I checked the personal hotspot connection via my USB cable and this is what I'm using now writing and posting this. So Good luck. Hopefully Apple will fix this bug in the next update.

System Extension Cannot Be Used: Soundflower Error?

I've had this issue for a long time now and I never knew what started it, it just started happening one day.andomly get
Anyways, I randomly get this pop up message that says:
System extension cannot be used
The system extension "/System/Library/Extensions/Soundflower.kext" was installed improperly and cannot be used.
Please try reinstalling it, or contact the product's vendor for an update.
There's no reason or rhyme to when it happens. I think maybe the app Boom that boosts volumes sometimes triggers it, but its never 100%. Also I googled around and I've tried some things like that restart the computer and have it run the system check and it didnt fix it
If anyone can point me in the right direction on what this might be I'd be very appreciative.

Open the Script Editor in the /Applications/AppleScript/ folder and run the following:
do shell script "chown -R root:wheel /System/Library/Extensions/AppleUSBEthernetHost.kext" with administrator privileges
You may then need to restart the computer.

2questions: system extension cannot be used and reinstalling updates

My error message on start up says:
*System extension cannot be used*
*The system extension “/System/Library/Extensions/SeratoScratchDriver.kext” was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update*
It appeared after I was in the middle of downloading software updates and my wireless dropped out. I downloaded them again to see if the error message would disappear once they were installed and then I got the never ending loading screen. I tried restarting and now it just starts up as normal with the error message still appearing. I also tried reinstalling serato scratch live. Any advice??
If I archive and reinstall leopard..which seems to be the best solution for the blue screen, will I lose any files? Do you think this might get rid of my error message as well?

That will happen if the kext is not owned by root and/or doesn't pass code signing verification. If an installer was interrupted then it probably didn't finish its job and you'll need to trash that bundle.

"System Extension cannot be used" problem...

Okay, so I have a brand new MacBook Pro, running the latest OS. Now, for some reason, I keep getting this error notice: "System Extension cannot be used."
I've been through DISK UTILITY, verified and repaired all "disk permissions," as well even "verified disk" (although nothing wrong or damaged have been found). I have even gone as far as ERASING my entire disk and RE-installing everything. However, no luck.
The thing is, verifying and repairing the disk permissions DO help, but there are still a number of extensions that do NOT get repaired. I don't know if this is significant, but I've had this problem 4 times in a row now, and after repairing the disk permission, the SAME EXACT extensions keep popping up as errors:
"System Extension cannot be used"
/System/libraryextensions/BJUSBLoad.kext
/System/libraryextensions/EPSONUSBPrintClass
/System/libraryextensions/hpdesignjetseries
/System/libraryextensions/hpDeskjet_ioenabler

/System/libraryextensions/hppsa640_ioenabler
/System/libraryextensions/hpqc_ioenabler
FYI: my ipod touch doesn't synch with itunes after the above errors are displayed, and I have to re-download itunes.
What do I do? Why is this happening? Is there a way to fix these extensions? Is this happening possibly due to 3rd-party plug-ins being used (am using Spectrasonics Trillian and Omnisphere with Logic Pro 9 - although this is running perfectly on my iMac AND on another MacBook Pro)?
Any help would be GREATLY appreciated, as I've got no more hair to pull out due to frustration! Thank you in advance!

But worse : all my new machines have been infected by the same error, because I did copy the oleder machine when installing them. Apple does not seem to care about this problem.
The solution should probably be that apple should make a fix, looking for old and uncompatible extensions and delete them or get the new ones from all the makers.
Apple! Who is going to face the problem ?

System extension cannot be used? (AppleAirport2.kext)

I rebooted my computer yesterday because it had started acting kindof slow for some reason. I figured that since quitting Safari, which had been open for several days, didn't do it- a reboot ought to.
When I logged in after rebooting, I got this message:
"System extension cannot be used.
The system extension "/System/Library/Extensions/AppleAirPort2.kext" was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update."
I haven't installed or tinkered with my computer recently, and it's been rebooted several times since the last time I had, so I don't understand why it suddenly seemed to forget it had an Airport Extreme card.
I tried throwing the Airport Extreme updates on a USB drive and reinstalling it, but it didn't do the trick.
It's running OS X 10.4, I'm pretty sure it's the .6 release, but I don't have the machine in front of me at the moment to verify.
Does anyone have an idea as to why this may have happened, or how I can fix it? Thank you so much in advance!

It is, indeed, running 10.4.6.
It was 10.4.5's combo update that had the file.
I tried installing and replacing the version of AppleAirport2.kext and rebooting and it didn't give that message when I logged in anymore. It still wasn't seeing that there was an AirportExtreme card present, though.
I deleted the file, as well as the two cache files as I had seen to try doing before I posted here, rebooted, installed the file with Pacifist.
I was using my PowerBook to check my settings here while the G5 started up. iChat on the PowerBook logged off, and I heard it log in on the G5!
Thank you both so much!

System extension cannot be used, now no AirPort Card Installed?!?!?!?!
