I’m attempting to run processing 3.5.3 on MacOS 10.14.3. When I click on the processing icon, Processing appears in the mac menu bar for moment, and then disappears. The splash screen never comes up. These are the errors I’m getting in my console.log. Any thoughts?

Searching for that error message:

…it looks like perhaps a Mohave bug, and updating to the latest beta worked for someone two days ago. Maybe try that?

On a whim, I tried installing Java 8. I know it’s not required for Processing, but that was the magic. I’m wondering if that might have handled a permissions issue. Anywho, thanks.

That is pretty darn mysterious – I thought that PDE uses its own Java internally, so changing the system Java shouldn’t affect it at all. You might want to report on this to Processing issues – in case others have similar problems.
