To find the Library folder on your Mac, you can follow the following steps: 1. Open the Finder window; 2. Click "Go" in the top menu bar; 3. Press and hold the Option (?) key to make the "Library" option appear; 4. Click to enter the Library folder. This folder contains subfolders such as application support files, caches, preferences, logs, and keychains, and is suitable for debugging applications, clearing caches, or managing extensions. If you need frequent access, you can run the "chflags nohidden ~/Library/" command through the terminal to make it permanently displayed. If you hide it again, use "chflags hidden ~/Library/".
If you're trying to find the Library folder on your Mac, you're probably looking for system files, app support folders, or preference files — things like cache data, logs, or settings that aren't meant to be front and center. Apple hides the Library folder by default in newer macOS versions to keep users from messing with important system files accidentally.
But don't worry — accessing it isn't hard once you know how.
How to Find the Library Folder in Finder
The main Library folder exists in two places: one for your user account and another for the entire system. Most of the time, you'll want the User Library , which contains personal settings, caches, and app-specific files.
To access your User Library:
- Open a Finder window
- Click the "Go" menu at the top
- Hold down the Option (?) key — this will make the "Library" option appears
- Click it, and the Library folder opens
This is especially useful if you're troubleshooting apps, managing extensions, or deleting leftover files after uninstalling software.
What's Inside the Library Folder?
Inside your Library folder, there are several subfolders you might recognize or need to interact with:
- Application Support – stores data used by specific apps
- Caches – temporary files that apps create (safe to delete occasionally)
- Preferences –
.plist
files that store app settings - Logs – diagnostic info from apps and system processes
- Keychains – security-related files (don't mess with these unless you know what you're doing)
You might end up here when resetting an app, clearing cache, or copying over saved game files. Just be careful not to delete anything you're unsure about.
Accessing Library Without Hiding It
If you find yourself needing frequently access to the Library folder, you can make it visible permanently in Finder:
- Open Terminal (
Applications > Utilities > Terminal
) - Paste this command:
chflags nohidden ~/Library/
- Press Enter — the Library folder now appears in Finder normally
It won't show up in the sidebar automatically, but it will appear in your home directory like any other folder. If you ever want to hide it again, just run:
chflags hidden ~/Library/
That's basically how you get to the Library folder and why you might need it. Not something most people use daily, but handy when you're deep into customization, debugging, or cleaning up after apps.

There are three ways to enable NTFS hard disk write permission on macOS: 1.

To use the iPad as a Mac sub-screen, you can use the Sidecar function. The steps are as follows: First, make sure the device meets the requirements (Mac will run macOSCatalina and above after 2016, and iPad requires iPadOS13 or above); then go to "System Settings" > "Display" on the Mac, click "Add Monitor" and select iPad to connect; if it is unable to connect, you need to check whether Wi-Fi and Bluetooth are on, and make sure the two devices are in the same network environment. In terms of connection mode, wireless is suitable for daily office work but may have delays, while wired is more stable and supports charging. The display mode is divided into two types: extension and mirroring. It is recommended to use extension mode to improve work efficiency. In addition, it can also be achieved through preferences

To share files between two Macs on the same network, first make sure that the two devices are connected to the same LAN, then enable file sharing on the host, set shared folders and access permissions, and then connect from another Mac through the access sidebar or manually enter the SMB address, and finally you can browse, copy or transfer files. Common problems include waiting or restarting the network when the device cannot be discovered. If the permissions are incorrect, you need to check the username, password and sharing settings. If the connection fails, you can try the SMB address. If the firewall blocks, you can temporarily close the test.
