You may need a "Windows Explorer" method to process all the hidden folders and files, that is, to display all the files (folders ).ProgramIn "open", drag and drop, and other more intuitive operations, please open terminal.
Terminal is similar to CMD and powershell in windows. If you are not a "Commander" in Windows, you may have to adapt to the use of command line style in Linux/Unix/MAC, because it will make your work faster and waste less time, you will like it! Terminal is a "black box" with "> _" in the upper left corner of the dock, located under application/utilities. Okay, run it!
(PS. In the next blog, I will tell new Mac beginners to open programs or files faster)
In terminal, copy or enter the following command (case sensitive ):
Defaults write com. Apple. Finder appleshowallfiles Yes
Then press Enter.
Restart the Finder by holding down the option key and clicking the finder icon on the dock. A menu will appear on the finder icon in about 2 seconds.
