    Tried running AJA System Test today on my startup now fails. Only thing I can think of is that it can't write the test file to the startup drive because it's Read Only now.

    I try to create a folder at the root and it asks for password.

    Just passing this on.

    Permissions on the / (root folder) have changed in Lion so that only root can write there. Can you create files in sub-folders, like /Applications or your home folder?
