Update to iTunes 9.0.3 (15)

Question

Update to iTunes 9.0.3 (15)

Ran this update and when it had completed, before the usual OK button could be clicked, this warning came up:

*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.

The updated iTunes runs and operates as expected.

If this is an 'HP' item can anyone explain the possible link to iTunes or why the warning message popped up at this time?
I rarely print but would like to know if this will raise issues with my HP PhotoSmart 5160?

Thanks for your help and input.

Mac Pro v Early 2008, Mac OS X (10.6.1), Best regards, FROG

Hello,
I also got this rather enigmatic warning while installing the iTunes 9.0.3 update via Software Update. A little investigation determined that it was related to my HP scanner (Scanjet 4670) which I had already confirmed was still functioning properly under 10.6.2. Other users have seen this warning prior to this, so its appearance seems to be somewhat arbitrary. The best way to determine if your printer is affected by this would be to try printing something.

Have a look at these two links:

http://discussions.apple.com/message.jspa?messageID=10266257
they may be more closely related to your circumstance.

I would guess that you could try moving the hpPlugInInit.kext to the desktop, reboot and try printing. If all is as it should be, you can probably trash it, as others have suggested, but test things first.

You might have to log in as root in order to move or trash this item, as kernel extensions normally don't like to be messed with by the user. Also, make sure your printer drivers are up to date; they should be available from the HP website, as well as from Apple.

Hope this helps, or at least points you in the right directions.

Thanks for the information P.G.Shaw, I did a search for the full warning message and then for some of the keywords to no avail, and there are masses of 'iTunes 9.0.3...' posts.

Fortunately my Printer is on the list of Apple Drivers. If the recently discovered issue is down to hpPlugInInit.kext hopefully it will be relatively easy to resolve. If not I feel a different brand of Printer coming on.

I also forgot my old HP Scanner 7490c, which although used even less than the Printer should also be checked. It is not on the Apple list but hopefully VueScan will save the day. HP are pretty dire at supplying support for this Scanner in UK. Bought in UK but only supported in North America! Switching from 'Windoze' (yes it often dozed) to Mac I was forced to get a contact in Canada to purchase the needed disc and send it on to me. I certainly will never purchase anything HP again.

Thanks again for your help.

Hi everyone!

I set a mod for iTunes to change appearance. it worked on iTunes 9.0.2 but no longer with 9.0.3 and it's very frustrating!
I was just wondering wether going back to 9.0.2 is possible or not!

Thanks!
