Whenever I try and launch processing, it does not load beyond this screen (see image attached). I have removed and reinstalled it, tried restarting my laptop too, but nothing works. I also tried downloading and testing older versions of processing but the same issue occurred. I am using a Mac (M2 Silicon, Sequoia 15.2).

I seem to have resolved the issue, it was related to the version of Java compatible with Processing not matching up with what was on my laptop for some reason.

Hi @nadine and welcome to the forum!

That’s interesting, could you share more details about how you solved the issue? This will be helpful for others facing a similar issue, and potentially help us address this in the Processing codebase itself! Thanks 🙂

Hi @sableraph, thank you!

After really digging and not finding any solutions I resorted to asking chat GPT to see if that would result in anything – turns out it did!

Essentially the recommendation was to download the latest Java version from this link: [https://www.oracle.com/java/technologies/downloads/?er=221886](https://www.oracle.com/java/technologies/downloads/?er=221886)

After doing that, it said to run this command in the terminal: java -version

Finally, it recommended redownloading Processing and opening it up either directly or from the terminal using this command: ./Processing

Also make sure to shift Processing from the downloads folder into the Applications folder.

Please note these instructions are specifically for a Mac.

I hope this helps! 🙂

Thanks for sharing! That’s unexpected though. Processing includes its own version of Java, so installing a separate JDK shouldn’t be necessary.

Which version of Processing were you using, and did you download the Apple Silicon build?

yup, I did use the Apple Silicon build and have Processing version 4.3.2

Processing is acting up again and the issue has come back. Not sure what to do this time.

Resolved using this command in the terminal: cd /Applications/Processing.app/Contents/MacOS  
./Processing --verbose
