• That is strange - Uncaught undefined, Execution Interrupted sort of implies that there's some code running on there for some reason.

    Do you ever see the:

    logo? Does it say the correct version number on it?

    The WiFi really shouldn't be able to cause your Mac to freeze though, I'd imagine that would be due to USB communications issues. Can you try with another Micro USB cable? It's truly amazing how many of them have data wires that are broken or which break.

    Maybe after a new cable, make sure you restart the IDE as @allObjects says, then try reflashing with 1v99 and check that it does get all the way through successfully. On Espruino WiFi the act of updating the firmware blows away any saved code, so hopefully when it succeeds the device should be 'as new'.
