How can I show full file path in Finder on Mac?

And again, you HAVE been given the answer to your request - TWICE.

Open Terminal in the Utilities folder. Run this command:

defaults write com.apple.finder _FXShowPosixPathInTitle -bool YES

Then this one:

killall Finder

Close Terminal.

Before running the commands, a Finder window only shows the name of the folder you're in:

After, it shows the entire path:

Had you actually followed the advice given, you'd already have what you wanted. Instead, you only seem to want to needlessly complain.

Finder > View > Show Path Bar. This will display a path bar at the bottom of the Finder window.

Also, in a Finder window's toolbar you'll find this icon to display the path to the displayed files/folders.

Trying to force an entirely different OS to mimic another OS is usually a lesson in frustration. But, Tesserax already gave you the answer:

If you want the full path to be visible in the title bar at the top of the window—so it’s more like Windows’ Explorer—go to Finder → Settings → Advanced, and enable Show all filename extensions (optional for clarity), then open Terminal and run:

• defaults write com.apple.finder _FXShowPosixPathInTitle -bool YES
• killall Finder

After this, the Finder title bar will show the full UNIX path for whatever folder you’re in.

You can also download OnyX and turn this ability on in its settings. It's actually the same as the command above. It's just that OnyX runs these Terminal/UNIX commands in the background.

Choose Show Path Bar from the View menu.

If you need this for a Terminal command:

drag and drop the file into Terminal window at the Terminal command prompt, and it will auto-insert a complete file reference there.

example:

type the Terminal command and a space

drag and drop the file to create a path reference in line

press return

> My question was perfectly on point.

Your question may have been valid. The point is that what you are asking for is NOT SUPPORTED.

The answers you received tried to tell you this.

MacOS Finder is not Windows File Explorer. Despite some similarities in function, there are just some differences that can not be bridged, and displaying full path names in the column list is one of them.

> The answer diverted to workflow

The responses gave you pointers to where you could get closer to what you want, at least to the point where you could see the path of selected items, but given that what you want CAN NOT BE DONE, there is no way anyone could offer more.

Use the macOS Finder as it is intended, not what you think it should do based on Microsoft's File Explorer. That dog won't hunt on macOS…

You can only see a Path Bar at the bottom of a Finder Window when either a folder from the Favorites listing is selected, or a specific file or folder in the current Window view is selected.

There is no need to visit Finder Settings > Advanced > Show all filename extensions. That is asking for useless clutter. The defaults write syntax that you were given above will work without the preceding sentence, but only show the enclosing folder of a selected file in the Finder WIndow title. There is a reason I never use this. The Show Path bar at the bottom of the open Finder Window will still display the path to the file.

Juvenile reply. Clearly many people want to display filepaths as there are add ins which can do this. But I don't want add ins for obvious reasons.

What part of, “macOS does not do what you want” do you not understand?

No, the reasons aren’t obvious. If you want something the OS doesn’t do natively you’re going to have to resort to some replacement or add-in if that exists.

Nobody here can make it happen and it’s not going to magically happen for you because you keep complaining.

Just ignore the overage and get on with solving your problems, and count your blessings that someone was willing to make suggestions that MIGHT be helpful, even if the answer was "too much" or “way off base”.

If important parts of your question did not get answered, just ask a more pointed question and Readers will try again.

While some individuals visit these forums seeking technical solutions to specific Apple-related issues, there are also those who seek recognition or fame through their contributions. 

Bitting the hands that feed the recipient will usually leave them hungry for technical advise

You should always use what suits you best. Perhaps you should return to Windows if macOS is not up to your expectations. Why continue to use a platform you consider not up to the task.
