How to Access the Library Folder in macOS? (User & System)

macOS隐藏用户库（~/Library）和系统库（/Library）文件夹，需按Option键点击Go菜单或用Go to Folder输入路径访问；可将用户库拖入侧边栏常驻。

To access the Library folder in macOS, you need to know that it’s hidden by default—both the user-level and system-level Library folders aren’t visible in Finder without extra steps.

User Library Folder

This is the one most people need: ~/Library, stored inside your home directory. It holds app preferences, caches, saved emails, fonts, scripts, and more.

• Open Finder, then click Go in the menu bar → hold the Option (⌥) key → Library appears in the dropdown. Click it.
• Or use Go → Go to Folder… (⇧⌘G), type ~/Library, and press Return.
• You can also drag the Library folder icon from the sidebar into your Favorites for quicker access later.

System Library Folder

This is /Library (root level), separate from your user folder. It contains system-wide resources like fonts, startup items, and network preferences.

• In Finder, choose Go → Go to Folder… (⇧⌘G), type /Library, and press Return.
• Note: You’ll need administrator privileges to modify most items here—and macOS may ask for your password before allowing changes.
• Unlike ~/Library, /Library doesn’t appear in the Go menu even with Option held down, so the Go to Folder method is the most reliable.

Make User Library Always Visible (Optional)

If you visit ~/Library often, you can show it permanently in the Finder sidebar:

• Open ~/Library using one of the methods above.
• Drag its window icon (the folder icon in the title bar) directly into the Favorites section of the Finder sidebar.
• It’ll stay there—even after restarts—so you can click it anytime without keyboard shortcuts.

Basically, it’s not complicated—just a matter of knowing where to look and how to reveal what’s hidden by design. No third-party tools needed.
