How to Configure the Spring-Loaded Folders Delay
The setting for spring-loaded folders can be found in the System Preferences menu on the Macintosh.
1. System Preferences can be accessed by double-clicking its Dock icon or by selecting Apple in the menu bar and then System Preferences from the drop-down menu.
2. In the System Preferences window, select Accessibility from the drop-down menu.
3. Select Pointer Control from the left-hand pane by scrolling down. When using an older version of macOS, you should select Mouse & Trackpad instead.
4. Select the checkbox next to Spring-loading delay and drag the slider to the desired position to control how long the cursor remains over a folder before it is automatically opened.
5. Confirm that the System Preferences window has been closed successfully.
