What are system preference files on Mac OS X?
Your Mac's system preference files are files that store the rules (or parameters) that tell your apps how they should work. And you can find these preference files within each applications' contents.

Mac OS X & macOS names. As you can see from the list above, with the exception of the first OS X beta, all versions of the Mac operating system from 2001 to 2012 were all named after big cats. Recently my main dev machine is a MacBook running OS X, so it felt reasonable to fiddle with making system calls of that platform. By the way, a system call is a function of the kernel invoked by a userspace program and it can be something like writing to a file descriptor, or even exiting. Mac OS X can only be run on systems built by Apple, such as the Mac mini, iMac, etc. This means that if you want to run Mac OS X without hacking it and then running it illegally, you will have to buy an Apple computer, which are more expensive than normal PCs, and may break your bank. Also, Mac OS X is, like Windows, mainly closed-source.
And what about broken preferences?
Well, with time, these preference files can be corrupted (or broken) due to things like: an app crash, a sudden blackout, or even hard drive corruption.

System 7 (whose codename being 'Big Bang' reflects the considerable changes that came with the OS) refers to the Mac OS that superseded 'The System' or 'System 6' before 'Mac OS' came into official use. The name reflects the version number of the OS7.0, but the term is also used to apply to all the 7.x versions, both those labeled 'System' and those labeled 'Mac OS.' System 7.0 was released.
Now, to fix them, we must delete them — Clean up these Mac preference files makes the app create a new, default preference file. This can help your app(s) operate correctly again. So, today, we'll go over two ways on how to remove system preference files: the easy way (with a utility), and the hard way (manually).

How to find system preferences on a Mac? All preference files are stored in [Your Home Folder]/Library/Preferences. Usually they named in this manner:
com.[name of the software vendor].[name of the application].plist
com.[name of the software vendor].[name of the application].plist
Now, if you have an application that works incorrectly, you can find the corresponding preference file in the above-mentioned folder and remove it from there. On the next launch of the application, it will recreate a default version of that file and then begin working properly. However, if this doesn't happen, that it may be a good decision to put the broken preference file back — They can be a bit temperamental. It's highly advised that you make a copy of the preference file before you delete it, just in case something goes wrong.
So, to remove unnecessary system preferences (or preference files that are bugging your your application), check the:
/Library/Preferences
/Library/Preferences
…system folder. To do this, open a Finder window, press Cmd+Shift+G and type the above in. However, be aware that items stored in that location could be incredibly important to your system and how it functions, so you should be 100% sure about the files you're going to delete.
