What else should I install [on macOS] and how do I do this, what do you recommend?
I would also recommend to install Pixie, an Apple app to visualize at the single pixel level
what gets drawn to any desktop window. I get it from https://developer.apple.com/download/more/
in an item called "Additional tools for Xcode 12" which contains Pixie as well as several other
apps.
Using that web site requires an Apple account, possibly an Apple developer account.
The free version of that account is enough.
About integration between working with windows and with the Terminal :
- it's possible to drag a file or folder from any Finder window and drop it to the Terminal
to get its full path.
- in Terminal, command "open /usr/local" will open that otherwise hidden folder in
a standard Finder window.
- in a Finder window, keep the cursor a second at the left end of the folder name
present in the window title bar, the folder icon appears which you can drag and drop
to a Terminal window in order to put there that folder full path.
