    I have 5 .kext files that pop up and say the same thing.


    Hey Apple, how about a little help here!

    It is possible that the respective kernel extensions are 32-bit and you're running a 64-bit kernel. See




    for instructions on how to deal with this.


    IMHO, the better option is to remove them and then update the software which installed them and depends on them. If the respective developer doesn't provide 64-bit kexts, chuck the software and get something different. Bugs and incompatibilities in kernel extensions have the potential of bringing down the OS. Unless I absolutely have no other choice, I do not install any software which requires a kext to operate.
