I’ve tried 3 different micro usb cables and none of them have had the Mac ask for a port for the Mayfly

Then I followed the steps above and am s…[Read more]

thanks again!

I’m using Arduino 1.8.19.

I’ve tried uploading a sketch (various ones) and get a not in sync error message that repeats 10x.  Entire error message below…

the port reads as follows (on my MacBook) p…[Read more]
