The network library, /Network/Library would store settings shared by all computers in a network domain - if a network domain admin set one up, which nobody does anymore; The system library, /System/Library, stores the base settings, resources, etc that come with OS X. In theory, you shouldn't change anything in here. /Library/ vs /System/Library vs /User/Library/ - Mac Applications & Software. Two, a Mac application can not read preferences from two files from two diferent libraries, 'interpolating' data or whatever you are trying to say. It will read from a.single. file with the most. Note: On OS X, files in /Library are not loaded at boot time when booting into Safe Mode. Location and 'blessed' folders. The System Folder is normally located directly below the root directory in the filesystem hierarchy, but does not need to be. The Mac OS identifies the 'System Folder' by undocumented characteristics that are independent of its name (it has different names in non-English. Nov 09, 2018 System Photo Library vs Other Library. When you run Photos app on your Mac first time this will ask you to create a new or use an old library. That default Photo library became the system library automatically.

The Libraries of Mac OS X: /Library
As I explained earlier in this chapter, this folder stores files that are available to all local users and that can be modified by an administrative user. Inside this folder, you will find the following folders.
Figure 4.10 The /Library folder.
Application Support
This folder contains accessory software for various applications, such as the StuffIt Engine.cfm file, used by StuffIt compression software.
ColorSync
The profiles you create via the ColorSync System Preferences window are stored here.
Contextual Menu Items
Third-party software that adds items to Mac OS X's contextual-menu feature (accessed when you Control-click an item) is stored here.
Desktop Pictures
The background pictures that you can select via the Desktop System Preferences window are stored here.
Documentation
Some programs that provide Read Me files and other documentation, accessed via commands within the application (such as Help), store their documentation files here.
Fonts
This folder is similar in function to the Fonts folder in /System/Library, except that these fonts are not considered to be essential. As an administrator, you can add fonts to or remove fonts from this folder.
SEE
'Take Note: Multiple Folders of the Same Name in Multiple Library Folders,' earlier in this chapter.
Internet Plug-Ins
Plug-ins used with your browser, such as the QuickTime and Shockwave plug-ins, are stored here.
Modem Scripts
This folder is the location of the modem scripts that you can choose from the Modem pop-up menu. You specify these scripts in the Modem tab for the Internal Modem protocol in the Network System Preferences window. (Whew—that was a mouthful of terminology!)
SEE
'Take Note: Modem Scripts,' in Chapter 8, for related information.
Create hidden folder mac. Sep 27, 2016 As you can see, the icon for the Library folder is faded, which means the folder itself is still hidden. Unhide the Library Folder Permanently. If you don’t want to open “Go To Folder” every time you want to access the Library, you can unhide the folder for good. To do this, open Finder, and head to your Home folder.
Preferences
A few systemwide preferences (.plist) files are stored here, such as those for loginwindow. In general, you will have little reason to modify preferences files in this folder.
SEE
- 'Take Note: Preferences Files in Mac OS X,' in Chapter 3, for more information on .plist files.
- Chapter 5 for more information on loginwindow.
Printers
This folder is where you will find support software for printers, in addition to the LaserWriter support files located in System/Library/Printers. In particular, drivers for Epson, Hewlett-Packard, and Lexmark printers are stored here.
SEE
Chapter 7 for more information on printing, including details on PPD and PDE files.
Receipts
Every time you install a Mac OS X update, a receipt .pkg file for the update is stored in this folder. In certain situations, as discussed in Chapter 2, the OS (especially Software Update) uses these files as a means of knowing that a given update has been installed.
StartupItems
This folder is the equivalent of the StartupItems folder in /System/Library. The main difference is that this folder is used for third-party software, as opposed to the preinstalled Mac OS X items stored in the /System/Library folder. If you install Timbuktu Pro, it will install a Startup Item in this folder. This item is needed for the Timbuktu software to be active at startup, no matter which user logs in. The actual Timbuktu application is located elsewhere, most likely in your Applications folder. Similarly, the Retrospect backup software also installs an folder, called RetroRunHelper, in the Startup Items folder.

There are multiple ways to look at Mac OS X and take it apart. Each way makes its own contribution to your understanding of the OS. In this sample chapter, Ted Landau looks at the major ways to 'take apart' Mac OS X.

There is more than one way to think about dividing up a pizza. First, there is the familiar method of dividing it into slices. Alternatively, you could divide it into layers: topping, cheese, sauce, crust. Theoretically, you could also divide it into its basic ingredients: flour, water, tomatoes, garlic, milk. Each method makes a different contribution to your enjoyment of the pizza. The first method (slices) is best when you're getting ready to eat the pizza; the second is best when you are deciding what to order (such as pepperoni with extra cheese); the third is best if you are concerned about nutrition (needing to know the exact ingredients to calculate calories).
The same is true for Mac OS X. There are multiple ways to look at it and take it apart. Each way makes its own contribution to your understanding of the OS. In this chapter, I look at the major ways to 'take apart' Mac OS X. Having at least a minimal knowledge of Mac OS 9 will help, as I occasionally make comparisons between the two OS versions. But even if you've never used Mac OS 9, you'll be able to follow along.

The Layers of Mac OS X: Aqua
Mac System Library Vs Library Of America
Aqua is the name given to what most users think of when they think of Mac OS X: the user interface, the Finder, the Dock, the windows, the translucent buttons, the high-resolution icons, the menus, and all the rest. Many users may never explore Mac OS X beyond its Aqua layer.
Mac Library Folder
From this perspective, a user upgrading from Mac OS 9 will feel quite at home, at least initially. Much still works the same way. You still double-click icons in the Finder to launch them; you still choose the Save command from an application's File menu to save a document; you still open a folder icon to see its contents.
But you will soon notice some significant differences: a new column view, a very different Apple menu, the Dock. I discussed the basics in Chapter 3, when I presented an overview of Mac OS X.
