Hello, I just like to bring to Blackmagic's attention that the drivers on the archive section of Blackmagic's website produce an error when extracting: "Unable to unarchive Decklink_Macintosh_7.9.6.zip into (the folder i'm in) Error:1 operation not permitted.
This is not a problem with my folders as I have tried extracting it to many different folders and it is not a permission issue, stuffit expander produces the same error, I've managed however to extract the archive with a 7zip variant called 7zx. However I do believe there is some problem with the archive and I do not trust the installation. Besides, unarchiving should just work with Apple's own archive utility. I've downloaded many times the same file on different days and from different computers and it still produces the same error.
