You can find the Home Folder by pressing Command + Shift + H in Finder, and you can then press Command + Shift + Full Stop to access the hidden files on your Mac.

You can also find the Library Folder by clicking on Finder, selecting Go in the Menu Bar, typing ~/Library into the textbox, and then clicking Go.

You can then close the hidden files by exiting Finder when you are finished.

There is a second Library Folder that is referred to as the Macintosh HD Folder, but it might not be called that on your Mac.

To access it, click on Finder and then select Preferences. On the Sidebar, find Locations, and then tick the box next to your Mac.

Once you have done this, the hidden files will be located as a disk under Locations in the Finder. To show the hidden files, you will need to select Command + Shift + Full Stop.

There is a third Library Folder that can be found in System. This folder contains macOS files and the third Library Folder can be found in the Macintosh HD Folder that is mentioned above.

It is important to make sure that you do not delete any of these files unless you have consulted a professional.

This will make the files visible to you, and then when you want to get rid of them again, just simply press Command + Shift + Full Stop again to hide the files.

If you want to be able to easily access the hidden files, you can drag the Hidden Library folder from the Finder Window to the Finder Sidebar. 

This will keep the hidden files visible after you have closed Finder. If you do not drag the file, the files will be closed down when you close Finder.
