Where Is Library Directory On Mac

The Library directories are where the system and your code store all of their related data and resources. In macOS, this directory can contain many different subdirectories, most of which are created automatically by the system. In iOS, the app installer creates only a few subdirectories in ~/Library (such as Caches and Preferences) and your app is responsible for creating all others.

Table A-1 lists some of the common subdirectories you might find in a Library directory in macOS along with the types of files that belong there. You should always use these directories for their intended purposes. For information about the directories your app should be using the most, see The Library Directory Stores App-Specific Files.

May 01, 2019  There are actually three library folders on a Mac. The library folder in the root directory of your system drive (usually called Macintosh HD) contains data accessible to all users, but only. I am trying to install the wire library. Do I copy the whole folder named 'wire' into the default location under the Arduino sketphad location? Or, do I take out the wire.h file from the folder, and copy it in to the sketchpad library directory that sits alone by itself? It's weird, but it took ages to even find where the libraries are for the Mac. Dec 12, 2016 Because the users /Library folder contains important data and files for Mac user accounts and apps to function, it’s generally a good idea to leave the directory and its contents alone unless you have ea specific reason to dig around, and know exactly what you’re doing. Casual users have no business in the /Library directory.

May 30, 2019 Despite the fact that Apple keeps the Mac Library folder hidden from users, it’s good to learn how to show the Library folder on Mac. You may need to access the Library folder when you need to clear cache, remove the app’s leftovers, edit preference files manually, etc.

Table A-1 Subdirectories of the Library directory

Subdirectory

Directory contents

Application Support

Contains all app-specific data and support files. These are the files that your app creates and manages on behalf of the user and can include files that contain user data.

By convention, all of these items should be put in a subdirectory whose name matches the bundle identifier of the app. For example, if your app is named MyApp and has the bundle identifier com.example.MyApp, you would put your app’s user-specific data files and resources in the ~/Library/Application Support/com.example.MyApp/ directory. Your app is responsible for creating this directory as needed.

Resources required by the app to run must be placed inside the app bundle itself.

Assistants

Contains programs that assist users in configuration or other tasks.

Audio

Contains audio plug-ins, loops, and device drivers.

Autosave Information

Contains app-specific autosave data.

Caches

Contains cached data that can be regenerated as needed. Apps should never rely on the existence of cache files. Cache files should be placed in a directory whose name matches the bundle identifier of the app.

By convention, apps should store cache files in a subdirectory whose name matches the bundle identifier of the app. For example, if your app is named MyApp and has the bundle identifier com.example.MyApp, you would put user-specific cache files in the ~/Library/Caches/com.example.MyApp/ directory.

ColorPickers

Contains resources for picking colors according to a certain model, such as the HLS (Hue Angle, Saturation, Lightness) picker or RGB picker.

ColorSync

Contains ColorSync profiles and scripts.

Logs

Contains log files for the console and specific system services. Users can also view these logs using the Console app.

Mail

Contains the user’s mailboxes. (Available in the user domain only.)

PreferencePanes

Contains plug-ins for the System Preferences app. Developers should install their custom preference panes in the local domain.

Preferences

Apple photos. Feb 21, 2020  If your Photos library is automatically updated with iCloud Photos, the entire contents of the library will re-updates with iCloud when the repair process completes. Bonus Tip: Create a new Photos Library. The other alternative way to repair corrupted Photos Library is to create a new Photos Library on Mac.

Contains the user’s preferences. You should never create files in this directory yourself. To get or set preference values, you should always use the NSUserDefaults class or an equivalent system-provided interface.

Printers

In the system and local domains, this directory contains print drivers, PPD plug-ins, and libraries needed to configure printers. In the user domain, this directory contains the user’s available printer configurations.

QuickLook

Contains QuickLook plug-ins. If your app defines a QuickLook plug-in for viewing custom document types, install it in this directory (user or local domains only).

QuickTime

Contains QuickTime components and extensions.

Screen Savers

Contains screen saver definitions. See Screen Saver Framework Reference for a description of the interfaces used to create screen saver plug-ins.

Scripting Additions

Contains scripts and scripting resources that extend the capabilities of AppleScript.

Where Is Library Directory On Mac Drive

The Library directory is a special directory used to store application-specific and system-specific resources. Each file-system domain has its own copy of the Library directory, with access levels to match the domain type. (See File-System Domains for a discussion of domains.) Although an application can use this directory to store internal data or temporary files, it is not intended for storage of the application bundle itself or for user data files. Application bundles belong in an appropriate /Applications directory, while user data belongs in the user’s home directory.

Important: You should not store user data files in the Library directory or any of its subdirectories. If your application stores the user’s data automatically—that is, without prompting the user for a location—you should choose a more appropriate location (usually the Documents directory) inside the user’s home directory. For the list of user directories, see The User Domain.

The Library directory contains many standard subdirectories. System routines expect many of the standard subdirectories to exist, so it is never a good idea to delete subdirectories of Library. However, applications can create new subdirectories as needed to store application-specific data.

Table 1 lists some of the directories that can appear in a Library directory. You should use this table to determine where to put files needed to support your software. This list is not complete, but it lists some of the most relevant directories for developers. Directories that do not appear in all domains are noted appropriately.

Table 1 Subdirectories of the Library directory

Subdirectory

Directory contents

Application Support

Contains application-specific data and support files such as third-party plug-ins, helper applications, templates, and extra resources that are used by the application but not required for it to operate. This directory should never contain any kind of user data. By convention, all of these items should be put in a subdirectory named after the application. For example, third-party resources for the application MyApp would go in Application Support/MyApp/. Note that required resources should go inside the application bundle itself.

Assistants

Contains programs that assist users in configuration or other tasks.

Audio

Contains audio plug-ins and device drivers.

Caches

Contains cached data that can be regenerated as needed. Applications should never rely on the existence of cache files. Cache files should be placed in a directory whose name matches the bundle identifier of the application. Cache data should further be subdivided into user or session-specific subdirectories as needed. (See Multiple User Environment Programming Topics in Mac OS X Documentation for user-specific guidelines.)

ColorPickers

Contains resources for picking colors according to a certain model, such as the HLS (Hue Angle, Saturation, Lightness) picker or RGB picker.
