Processing (all versions) does not launch and remains stuck on startup window on Mac (Resolved)


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 :slight_smile:

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

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! :slight_smile:

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
