There is already a confirmation MessageBox when you try to remove all plugins.
It works on my mac just now. If your mac skips it, then that is a bug in Qt 6.5.2 that is fixed in Qt 6.5.3

void PluginWidget::removeAllPlugins()
{
    PluginDB *pdb = PluginDB::instance();
    QMessageBox msgBox;

    msgBox.setIcon(QMessageBox::Warning);
    msgBox.setWindowFlags(Qt::Window | Qt::WindowStaysOnTopHint);
    msgBox.setWindowTitle(tr("Remove All Plugins"));
    msgBox.setText(tr("Are you sure sure you want to remove all of your plugins?"));
    QPushButton *yesButton = msgBox.addButton(QMessageBox::Yes);
    QPushButton *noButton  = msgBox.addButton(QMessageBox::No);
    msgBox.setDefaultButton(noButton);
    msgBox.exec();
    if (msgBox.clickedButton() == yesButton) {
        ui.pluginTable->setSortingEnabled(false);
        while (ui.pluginTable->rowCount() > 0) {
            ui.pluginTable->removeRow(0);
        }
        pdb->remove_all_plugins();
        ui.pluginTable->resizeColumnsToContents();
        ui.pluginTable->setSortingEnabled(true);
    }
    foreach(QComboBox* cb, m_qlcbxs) {
        cb->clear();
        cb->setCurrentIndex(-1);
    }
}
