Hi: I am attempting to run the Blink sketch on my Arduino with IDE 1.8.7. I seem to be stuck on compiling at the following point:

Normally, I can work this out, but, I am really stuck on this one. It appears to have something to do with Java; I have the latest Java installed. Can anyone help?

The following solved my issue; its not obvious:

Apple no longer include the Command Line Tools package in upgrades to the OS. These are required to run Arduino and incidentally some Python editors.

Do the following:

  1. Go to https://developer.apple.com/download/more/

  2. Sign in. Don't worry, just sign in with your Apple ID. You don't have to be a developer.

  3. In the list that follows search for the Command_Line_Tools package that corresponds to your Mac upgrade. In my case it was for 10.14.

  4. Download and install that package. It may take a while to open this before it begins to install the package.

  5. After that Arduino should run normally.
