如何检查 Python 或终端中的 Retina 显示屏？

Question

I use the Python module pyautogui .
It has problems with Retina display's and i must check if the script runs on a computer with a retina display.

I found this code, but it's not working (anymore).

if subprocess.call("system_profiler SPDisplaysDataType | grep 'retina'", shell=True) == 0:
        IS_RETINA = True

Is there any other command to check if the computer has a retina display?
I use OSX Mojave 10.14.6

if subprocess.call("system_profiler SPDisplaysDataType | grep 'retina'", shell=True) == 0:
        IS_RETINA = True

to

if subprocess.call("system_profiler SPDisplaysDataType | grep -i 'retina'", shell=True) == 0:
        IS_RETINA = True

and it worked.

Try that
