How to show hidden files on mac using mouse (without Terminal or Keyboard shortcuts) I want to see the hidden files in all the directories of mac. Also, I want to change this setting so that even after restarting mac I should be able to see these hidden files/folders
If you use the 'old-style' Terminal command, the view ought to stick through reboots.

The simple Terminal command is

defaults write com.apple.finder AppleShowAllFiles TRUE; killall Finder


However, as you want to do this by mouse only, you will need to wrap this into an Applescript, saved as an application.

From my own answer at How to set ⌘ + H to enable show hidden files if you use the following script, saved as an application, you can invert the hidden flag by simply double-clicking the app.

set newHiddenVisiblesState to "YES"
try
    set oldHiddenVisiblesState to do shell script "defaults read com.apple.finder AppleShowAllFiles"
    if oldHiddenVisiblesState is in {"1", "YES"} then
        set newHiddenVisiblesState to "NO"
    end if
end try
do shell script "defaults write com.apple.finder AppleShowAllFiles " &amp; newHiddenVisiblesState &amp; "; killall Finder"
