ITunes For Mac :: System Extension Cannot Be Used After Installing 11.4
Sep 10, 2014
Installing latest version of iTunes (11.4) today led to the following error message: System extension cannot be usedThe 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. And what does it mean for the continued safe operation of my MacBook?(Other than the distraction of getting a worrying error message that I take time out to report?)
Info:
MacBook Pro, OS X Mavericks (10.9.4)

I responded to the upgrade of iTunes today - to version 11.4. I did this in short succession on a Macbook Pro and iMac, both running Mavericks. On both machines I got an error message immediately after the upgrade as per the attached image...

When I try to install iTunes 9 I get the following message: "System extension cannot be used. The system extention "/system/library/extensions/CDSDAudioCaptureSupport.kext" was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update". ITunes installs anyway - even if I leave the message there without clicking "OK". I have verified my disk and repaired the permissions - yet still pops up.

I have a problem with Norton AntiVirus and have spent hours on-line with three levels of Norton Engineeers. Norton will not perform an idle-scan and loses its license on restart, requiring re-entry of the product key.
When removing Norton files for a re-install an alert pops up System extension cannot be used The system extension "/System/Library/Extensions/SymInternetSecurity.kext" was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update. As noted, I have spent many hours on the phone and LiveChat with Norton engineers. The last one has suggested I contact Apple Support for assistance. They will call back on Monday. I am running a 15" MacBook Pro (Early-2011), 2.3 GHz Intel i7, 8 GB 1333 MHz DDR3, OS X Lion 10.7.3, 512 GB Solid State SATA (Crucial)

That's the message I got when adding a new printer driver. The reference was system/library/extension/cnqe202-classicnotseize.kext. Or close to that. I think I got that message also when upgrading to 10.6.1. As I recall there was also a note about updating this extension but no info on how to do it. Searching for .kext brought up a long list from last August having to do with crash reports with skype, real player, fire fox and a couple more; but nothing permanent and everything is working fine. Anyone have any thoughts about this? I'm using an iMac, 20".

As I understand it the MDP from the 5770/5870's have audio support. So does the cable from the new 27" LED display. Do MDP extension cables that can also carry the audio exist (e.g., is Atlona AT13032-2 such a cable)?

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 had a MacBook a while back and it broke. I managed to salvage the HD and the RAM. Soon, I am going to buy another MacBook (new white plastic, nvidia series) and I was wondering if I could just remove the HD of that machine and put in the old HD from my last MacBook? Would it still work like the last one did, or would there be differences because of new hardware? Not sure about this at the moment.

So I bought the $29 single user version. When installing it didn't ask for a serial code or anything. Can this disc be used to upgrade other systems?

I was wondering if anyone is uncomfortable with the future of doing all OS X updates in the App Store? I've always downloaded the combo updaters from Apple's website and installed from my hard drive. When I installed Lion I downloaded it from the App Store and then burned it onto a bootable DVD and installed Lion after booting off the DVD. And even before that I check the hard drive with disc utility and repair permissions before and after installation. Also shut down my mac and unplug all peripherals and then start back up. I've never seen apple suggest these things. So I wonder is Apple just a little too confident in OS X? Is OS X even more reliable than ever? Or am I just superstitious with the Mac voodoo?

I am trying to install a full Lion system on a USB key. I am not talking about a Cracker Jack installer and disk utility thing. I am talking about a full useable system. Why would I want to do this? Let's see, I have a 3 month old MacBook Air with a failing SSD, a brand new Mac Pro with NO THUNDERBOLT jack, an over-designed FireWire to Thunderbolt dongle that Apple took 2 YEARS to develop and still has yet to bring to market (which may or may not support Target Disk Mode on FireWire Macs... like my brand new tower) and NO way to run Carbon Copy Cloner on a booted system that can see the failing SSD as a local disk. I'm sure I don't need to mention the kick in the pants that is Spotlight trying to index a failing drive, corrupting data as it does so. Sorry but I don't have access to a THIRD mac with Thunderbolt. Just these two very new machines. If there is no way to get the MacBook Air mounted in Target Disk Mode on another mac, I need to boot it from a System that is not corrupting files like crazy due to media failure. I can't use the brilliant new "Recovery Partition" thing they created because, well, that's also on the failing disk.
When I run the 10.7 installer on the MacBook it says this is an unsupported system. Years ago it was possible to install OSX to a disk other than the boot disk without rebooting the machine. Not any more. When I clone Mac OS Install ESD to a thumb drive and try to boot from it, I get the big X. When I try to make the USB key on the tower, after needlessly rebooting it, of course, using ANOTHER USB key with the ESD image, my target USB key (which is 64gb) is greyed out, and hence not selectable as a target volume for the installation.

I have a 13" mid 2009 MBP and due to issues with the superdrive I decided to buy the OWC data doubler kit and install it with a 120GB SSD from them. I also upgraded to 8GB RAM at the time but I do not believe that has anything to do with this. After I did this, my original HD freaked out and wouldn't even show up in target disk mode. Eventually I made a clone of the Snow Leopard install disks onto a USB stick using a friend's laptop and installed OSX fresh onto the SSD. Luckily I had a backup of everything so I have not lost anything. Even with the fresh install, however, I am having a lot of issues with the OS. When I try to boot the machine, it often takes 3, 4 or even 5 times to boot normally. As far as I remember, booting into safe mode works right away but that is obviously not a solution. Usually it starts by hanging at a blue screen once or twice, then I can get to the login screen but it is either kind of grayed out or it just freezes and I can't even move the mouse to type in my password. When I do safe mode it boots up without this issue, but even after that I often see the computer freeze up during use, which happened the first time I wrote this post. This problem also occurs when waking up from sleep. If the laptop goes to sleep by itself or I close it, I have to power cycle it to return to use. The keyboard will light up, but the screen never comes on so there is no way for me to log in. These issues are extremely frustrating and make me feel dumb for doing this in the first place, considering that everything worked ok before(minus the superdrive). Has anyone seen these issues before? Resetting PRAM and booting into single user mode are not helpful, I have tried them many, many times and I see the same issues. I saw somewhere else that I should try to remove the fonts, startup items, and loginwindow.plist files/folders and put them on the desktop, but even after doing that the issues persist.

I'm a former windows user and I'm still learning about OS X. I hate installing programs that leave behind all kinds of files though, especially when they slow your system down like in windows. I'm wondering, when you download, install, and then uninstall widgets, do files get left behind afterwards?
