Quoted from goldsmid:I have used a number of different brand cards and sizes. Class 10 is important and having a decent transfer rate, but most current SD/MicroSD cards have a good rate. The trick I have found to get them to work is using the correct image burning program. If you are using a Mac, you have to use the command line approach through the terminal. If not, then the code will freeze and videos will not play correctly.
This what i found. I used Etcher on Mac abd it works preet good but sometimes it will restart and is a bit glitchy with the up post and afew other things. How does the other command line work on mac
