I am a newbie at flying and using forums such as this. Downloaded rc7 and rc8 from apple on July 23, Using an AeroflyRC flight controller, have had little luck setting up both of them. I could really use someone to walk me through the process if anyone available to help me. Efforts at following instruction online from Apple, manufacturer, and other online forums haven't seemed to work for me. If anyone available to help, I can supply more in information if anyone willing to help. Computer is Mac mini (late 2014), mac OS Mojave Version 10.14.6, 8 GB memory, Intel Iris 1536 MB Graphics, Serial number CO7QJ473G1HW. Please be gentle, I'm embarrassed enough not being able to figure this out myself .
