Hold down the option KEY in the finder and under "Go" section in the menu, you'll see the option to show the "Library folder", which does not usually show, because it's important that it is not deleted or changed unless you know exactly what you are doing. There's another Library connected with the System -operating system, which you can show by holding down "Shift -Command - Period". Best to hide that folder because you definitely do not want to change anything there, so click one more time the same key combination to hide it once again. There are actually three different libraries, but the one that shows in the finder under the go menu is it one you might want to remove orphan files associated with applications you decide you do not want. That's a good time to use the well-known app Find Any File, and hold the option key down before hitting the "Find" key. You'll have to enter your computer's password, and the Find will change to "Find All". This allows Find Any File to search your start up drive at all levels. When it's finished the upper left display option will show every instance of the word that you are searching, and the one next to it will show you the pathway to that file. Holding down the option key will allow to show that file in the finder, among a number of other options. I believe they finally put it in the App Store, but charge $8. Go to Thomas Templeton website and you can use it as long as you want, fully functional, but you'll get an occasional reminder for a donation. You can purchase it there for $6.
No need to purchase until you decide it is very functional for you. Been using it for about 10 years and think I donated twice, as it is one of my essential "go to apps" to find orphan files that might be slowing down your Mac, or associated malware files. Cheers. Seth
