Show ALL files starting with a dot in Finder This answer from 2011 doesn't work for me:
defaults write com.apple.finder AppleShowAllFiles true
killall Finder

I still can't see .DS_Store for example, .localized, ._. etc
cmd shift . also doesn't work.
I can see other dotfiles after I use cmd shift ., just not ._.*, .DS_Store, .localized so far.

Once you are in the desired directory you can type ls -la to see a list of all the files and folders included the hidden ones that start with a &quot;.&quot; You can open the files using the open command followed by the file name. You can also go inside the hidden directory by using the same cd command from before followed by the directory name.
