    Just updated to 10.12.5 with the latest patch and now the kext's I had working are A: not 1.5.1 versions nor are they B: working, but throwing up a signature validation error code -67030

    Anyone else having the same problem...?

    I knew I should have just left things alone :)

    Thanks in advance if anyone can help and get me back to normal.
