Mac OS X Snow Leopard – Error CNQL2410_ClassicNotSeize.kext was installed improperly

Posted on


Does anyone know how to fix this problem?

The system extension CNQL2410_ClassicNotSeize.kext was installed improperly.

I’m not sure what is triggering the error.


Have a look at the Canon site.

They have uploaded some new Snow Leopard (10.6) compatible drivers as at 9 September 2009.

Seems to fix the problem for me.

It’s happening on my Mac too, I think it’s something to do with the Canon Scan Gear software and a PowerPC component that won’t run because the default installation of Snow Leopard doesn’t include Rosetta?

I haven’t tried this yet but either install Rosetta (a dialogue will ask you to do this is you launch a PPC app) or see if you can find a Snow Leopard compatible scanner driver on the Canon site.

fwiw, i just got the same error message while installing an updated Line6 driver and i do have Rosetta installed. i do also have a CanoScan LIDE scanner and what little turns up on Google suggests that this may the source of the problem. why installing a Line6 driver triggered for me, though, i do not know. possibly a freakish coincidence.

the same message appears after the installation of Vodafone Mobile Broadband GMC on my MacBook (and it don’t work with Snow Leopard …)
p.s. I also have a Canoscan LIDE 500 F
p.p.s. installing the old Vodafone Mobile Connect I obtained 5 (!!!) Kernel panic … so, do you know if exists an universal drive for Huawei E272 ?
