I started from the examples in
https://doc.qt.io/qt-5/stylesheet-examples.html#customizing-qtabwidget-and-qtabbar
and with the help of
https://doc.qt.io/qt-5/stylesheet-reference.html
I arrived at the example below, which reproduces quite well the
default style on Mac, while also fixing the display of the text in the
tabs.

Thanks for your help!
Best wishes.

Example:

from PyQt5.QtCore import Qt
from PyQt5.QtWidgets import (QMainWindow, QVBoxLayout, QWidget,
QApplication, QTabBar)
from PyQt5.QtGui import QIcon

qApp = QApplication([])
win = QMainWindow()

win.tabBar = QTabBar(win)
win.tabBar.setExpanding(False)
win.tabBar.setElideMode(Qt.ElideNone)
win.tabBar.setTabsClosable(True)
win.tabBar.addTab(QIcon('text-plain.svg'), 'Untitled')
win.tabBar.addTab(QIcon('text-plain.svg'), 'Untitled 2')
win.tabBar.addTab(QIcon('text-plain.svg'), 'Untitled 3')
win.tabBar.addTab(QIcon('text-plain.svg'), 'Untitled 4')
win.tabBar.addTab(QIcon('text-plain.svg'), 'Untitled 5')

style = """
QTabBar::tab {
    background: white;
    border-style: solid;
    border-width: 1px 0px;
    border-color: #ACACAC;
    min-width: 8ex;
    padding: 2px 4px 2px 2px;
}

QTabBar::tab:selected:active {
    border-color: #045FFF;
    background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1,
                                stop: 0 #69B1FA, stop: 1 #0C80FF);
    color: white;
}

QTabBar::tab:selected:!active {
    border-color: #ACACAC;
    background: #E5E5E5;
}

QTabBar::tab:first {
    border-left-width: 1px;
    border-top-left-radius: 4px;
    border-bottom-left-radius: 4px;
}

QTabBar::tab:!first:!selected:!previous-selected {
    border-left-color: #E5E5E5;
    border-left-width: 1px;
}

QTabBar::tab:last {
    border-right-width: 1px;
    border-top-right-radius: 4px;
    border-bottom-right-radius: 4px;
}
"""

win.tabBar.setStyleSheet(style)

layout = QVBoxLayout()
layout.addWidget(win.tabBar)

mainwidget = QWidget()
win.setCentralWidget(mainwidget)
mainwidget.setLayout(layout)

win.show()
qApp.exec_()
