问题 What terminal command can I use to terminate the cursor/mouse process on a MacOSX?

问题 I'd like to be able to obtain a list of strings of all the window titles on macOS from a Python script. On Windows, there's a win32 api (the enumWindows() function) that can do this; I'd like the macOS equivalent. Is this possible?

问题 I'm following https://ninenines.eu/docs/en/cowboy/2.0/guide/getting_started/ which requires make. When I run the install scripts, the prompt tells me to use make 4.1 . I run brew install erlang git homebrew/dupes/make then brew unlink make && brew link make but which make is still /usr/bin and make -v is 3.8. How do I link to the correct, updated make?
