“I just got a new 2017 MacBook Pro. I ran into an issue when I attempt to open an MKV file. I prevents it and says it is a unverified app and I need to go into System Pref to Security to allow OS X to open it. It does this for all MKV files. Why is it treating them like an app instead of a file and is there a way to fix this. My 2009 Macbook Pro never had this issue.”
