How do I type in pyautgui on macOS?

If you press the key marked '[', '@' will be entered.On the other hand, if you press the key marked ']', '[' will be entered.

Judging from this phenomenon, it seems that macOS recognizes that the English (ANSI array) keyboard ('[' on the right side of 'P' is used, but the Japanese (JIS array) keyboard ('@' on the right side of 'P') is used.

You can use the Keyboard Settings Assistant (app) to change the keyboard settings in macOS, but there are three ways to launch it:

(1) Apple Mark - > System Settings - > Keyboard - > Change Keyboard Type
(2) Start the terminal and do the following

open/System/Library/CoreServices/KeyboardSetupAssistant.app

(3) Launch Finder, follow the path above, and open KeyboardSetupAssistant.app

When the "Keyboard Settings Assistant" is started, follow the instructions and the keyboard type will be selected appropriately at the end, so it will be "completed."

The "Keyboard Configuration Assistant" can be used at least in macOS 10.13 (High Sierra) or later.
