Hi,
Brand new Arduino UNO WiFi R4.
When I plug it into my Mac, the LED matrix displays prettily and ends up as a nice heart.
The yellow LED labelled "L" flashes crisply.
When I press the reset button it all repeats as if I have just turned it on.
If I double-click the reset button the yellow LED fades in and out.
In the IDE, I open the Blink example. It compiles just fine, but will not download.
This is a printout from my serial window:
