Hello

I get a error when I execute any code with P2D or P3D on my new mac studio. The console is laconic : “could not run the sketch"“. It seems to be a problem with the metal renderer. Here is my configuration :  
Max Studio M1 Max Tahoe 26.1  
Processing silicon 4.5.2  
Does anyone has a solution to share.  
Here is below an extract of the apple’s detailed report :

I have no answer for your question, but can confirm that there may be a problem with Tahoe and Apple silicone systems. I tried the following code on a new M4 with Tahoe 26.2 using both P3D and P2D renderers:

```processing
void setup(){
  size(600,600,P3D);
  rect(50,50,200,100);
}

```

The demo ran, but the **rectangle flickered rapidly**. The FX2D renderer worked as expected; no flicker. This was with Processing v4.5.2.

**Work around:**

Adding an empty _draw()_ will stop the flicker.

Hi @MickaelLafontaine777 and thank you for reporting this and including the logs. Sorry you’re running into this.

I haven’t seen that one reported before. Would you mind [opening an issue on GitHub](https://github.com/processing/processing4/issues/new/choose) so maintainers can have a look?

(Raphaël)

There is a short video here which shows the problem on MacOS M4 Tahoe 26.2:

**Addendum:**

This was reported as an issue and adding an **empty** _draw()_ was suggested as the workaround. However, if code is added to the _draw()_ whatever graphic was coded for in _setup()_ is not visible. For instance, the rectangle() in the above example does not display if a circle() is added to _draw()_.

Hello Svan Hello Raphaël  
Thanks a lot for your answers!  
I’ve created a github report : [P2D / P3D doesn't work on a M1 Mac Studio · Issue #1426 · processing/processing4 · GitHub](https://github.com/processing/processing4/issues/1426)  
As I said in the report the mac studio has a special configuration. Since it is used as a media server for an immersive room, it has 7 connected screens : 4Kx4 and Full HD x 3. I will do more tests (one screen only, another mac studio model). I keep you in touch.  
Best

I already turned it in for M4 because I didn’t think you were going to do it. Sorry. My issue is [#1422](https://github.com/processing/processing4/issues/1422). Yours could be a different issue however because it doesn’t run and my issue runs but has bad output.
