[Bug]: Plot window not shown in Mac OS with backend set to default MacOSX #26869
Description
Bug summary

Code for reproduction
import matplotlib
import matplotlib.pyplot as plt
import numpy as np
from matplotlib import cm
# matplotlib.use(backend="TkAgg")
plt.style.use("_mpl-gallery")
# Make data
X = np.arange(-5, 5, 0.25)
Y = np.arange(-5, 5, 0.25)
X, Y = np.meshgrid(X, Y)
R = np.sqrt(X**2 + Y**2)
Z = np.sin(R)
# Plot the surface
fig, ax = plt.subplots(subplot_kw={"projection": "3d"})
ax.plot_surface(X, Y, Z, vmin=Z.min() * 2, cmap=cm.Blues)
ax.set(xticklabels=[], yticklabels=[], zticklabels=[])
plt.show(block=False)
input("Hit [return] to end")
plt.close("all")Actual outcome
No plot is generated.
Expected outcome
Additional information
If the code line
matplotlib.use(backend="TkAgg")
is uncommented the code will work as expected.
