> I just want a full path in the header/title bar
Apart from the Path bar in the bottom, there is also an old school title bar method:
defaults write com.apple.finder _FXShowPosixPathInTitle -bool true
killall Finder
("false" for reversing it.)
It doesn’t work for great for tabs, though, because tabs are short and paths are long.
> Or let me copy the full path …
There are some alternative fun and old methods:
* If you're hovering over the title bar of a finder window there is a little folder icon, the so-called proxy icon which gives access to the current folder. One can drag and drop it and it moves the folder. Dragging a folder or the proxy icon on the Dock icon of Terminal or iTerm opens a new window with the working directory directly set to the folder. But dragged into a text field you're getting the text path. Right click gives you a dropdown for navigation in the current folders path.
The proxy icon was stable in Finder until recently, now you need to hover. But you can re-activate the permanent display of the proxy icon under System Settings → Accessibility → Display, I think.
* MacOS has, since the Next days, the concept of Services. Services are little actions which the System and (good) Apps can provide to do something with with something. Services are found in the context menu or the App menu. If you're right clicking on a folder (sadly not the proxy icon), there are Service Actions by Terminal and iTerm for opening a window or tab for a selected folder.
* AppleScript:
tell application "Finder"
if exists window 1 then
set currentDir to POSIX path of ((target of front Finder window) as text)
else
set currentDir to POSIX path of (path to desktop folder)
end if
set the clipboard to currentDir
end tell
It works in Script Editor at least. I'm not an AppleScript expert.
But you can use AppleScript everywhere in MacOS. The Script-Menu, as an own App, as an Automator action or a Shortcut, you can give those hotkeys, possible use them in Alfred or Raycast, etc.
Apart from the syntax it will be a sad day, if Apple retires the AppleScript architecture.
