hello! I have recently bought a hero 7 black and bought it because I’ll be taking it to Bali in December. So, I thought of testing it at my friends bachelorette weekend getaway. I was able to record quite a few videos. However, when I got home, I connected the microsd connector to my laptop and download all the content saved. I only saw a handful were able to be seen via QuickTime and the rest could not be read/opened. The files are .MP4. I have a MacBook Air that I bought either 2011 or 2013. I am hoping to see if anyone had this issue and how I can fix it. I would appreciate the help greatly! Thank you!
