Frame skips on h264 after copy onto mac.

[jonnyginese]

Hey guys, has there been any other reports or solutions to this?  I've been working with my production team and it seems to only happen when its copied over to a mac.  I've never had the issue when copying to my PC whether I use USB2 or USB3 ports or any reader.  Its happening on 2 different 5d3's that are both running ML.  The footage plays back properly in camera but after copied to the Macbook Pro the footage has random frame skips/rips.

Any help would be greatful to make sure this doesn't keep happening.
