egui 0.33.3 crashes on macOS Sequoia 15.7.3 when closing the application

[nczyw]

CPU: 2.8 GHz Quad-Core Intel Core i7
GPU: Intel Iris Plus Graphics 655 1536 MB
When closing the application, it crashes. During debugging, the program gets stuck at this line of code:
unsafe { msg_send![receiver, sel $ (, $ a)*] }
The debugger shows:
EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)
Test code as follows:

[package]
name = "eguitest"
version = "0.1.0"
edition = "2024"

[dependencies]
eframe =  "0.33.3"

use eframe::egui;

fn main() -> eframe::Result<()> {
    let native_options = eframe::NativeOptions {
        viewport: egui::ViewportBuilder::default()
            .with_inner_size([400.0, 300.0]),
        ..Default::default()
    };

    eframe::run_native(
        "macOS test",
        native_options,
        Box::new(|_cc| {
            Ok(Box::new(MinimalApp))
        }),
    )
}

struct MinimalApp;

impl eframe::App for MinimalApp {
    fn update(&mut self, ctx: &egui::Context, _frame: &mut eframe::Frame) {
        egui::CentralPanel::default().show(ctx, |ui| {
            ui.heading("test");
            ui.label("test");
            
            if ui.button("close").clicked() {
                ctx.send_viewport_cmd(egui::ViewportCommand::Close);
            }
        });
    }
}

The program works fine on Windows. I’m not sure if macOS is different in how it’s used. I hope my program can run on multiple platforms.

From the error message, it seems that the issue is caused by a conflict related to the Touch Bar. I don’t understand why egui would be interacting with the Touch Bar at all.

[connorslade]

I found that setting persist_window in NativeOptions to false stops this crash. I don't use the persistence feature so this is enough of a fix for me.

[nczyw]

I'm using this solution too. egui has a close event, so I handle persistence there.
