    I'm getting this error while trying to install my certificate from Program portal. "Certificate cannot be used, unrecognized critical extension"

    Theres abosulely nil info on this via googling.

    Does it refer to the keychain app version? maybe its not updated enuff?

    Cuz i'm using 10.5.1. and havent updated... its going on now..!

    In xcode a similar error pops in something to do with unrecognized extension.?

    any help is appreciated?

    i think you are correct with your assumptions that you need to update to make it work properly.
