Just starting out the 16th Chapter of “Processing: A Programming Handbook for Visual Designers and Artists” and I ran into an error of sorts on the first example.

I am getting some red warnings and the program won’t run - except once I click the red exit icon on the window it will load very briefly before closing. See screenshots.

I am using Processing 3.5.4 on a 2015 MacBook Pro running OSX 11.5.1

Tried the usual tricks of restart, no external monitors, etc. Same result.

Ran the example “[box](https://processing.org/reference/box_.html)” code from the reference as well and same problem.

I know the textbook is based off of the 2.0+ distro but the reference page has the same result as noted above. I get the same problem for every example in the chapter.

Here is the error:

```auto
||0 AppKit 0x00007fff22c38261 -[NSWindow(NSWindow_Theme) _postWindowNeedsToResetDragMarginsUnlessPostingDisabled] + 352|

```

Any ideas on how to rectify this?

Thank you!

For what it’s worth this did not happen in Processing 4

Hello,

Take a look at this topic:

> [@Big Sur and new Macs](https://discourse.processing.org/t/big-sur-and-new-macs/25374/5):
>
> A blank screen while using processing on Big Sur happens on older machines as well, not just M1. For myself it affected P3D programs. A user on the Github site has indicated that including frameRate will let the screen display normally. I have tested this with several P3D examples myself.

Thank you for the reply.

That trick of including frameRate(30); in the sketch did allow it to run though the error was still present in the console.

Good to keep this in mind!
