So I bit the bullet and went with a Macbook Air. Boy am I disappointed! I have a Hero4 Gopro and when editing a in the Gopro Editor I try to move my video to the conversion list and I get an error :Volume "Macintosh HD" is 249.80GB with a maximum file size of 9.223372036854776e+18, GOPR0097.mov requires 37066.66TB...
So I am not able to edit any of my videos because MAC can't handle the load? This is the 3rd work around I had to do with a MAC getting ANNOYED!! HELP!

As they say, don't bring a knife to a gun fight.

firstly don't expect to be able to edit 4k video with anything but the fastest laptop... Mac or Windows makes no difference.

secondly the error you have sounds like it could be a corrupt file. Not the macs fault. Have search on google for corrupt files And GoPro. it seems you should only use memory cards approved by GoPro.
