Group albums in folders in Photos on Mac
You can create folders to group your albums. For example, you could create a folder named “Vacations” and put all the albums of your vacations into it. You can also create folders inside other folders.
Create a folder
In the Photos app on your Mac, click My Albums in the sidebar.
Choose File > New Folder.
Type a name for the folder.
Drag albums into the folder.
Tip: To quickly create a folder, Option-drag one or more albums onto another album. Photos places all the albums in a new folder. You can also drag other albums into the new folder.
You can’t move shared albums into a folder.
Remove or rearrange albums in folders
In the Photos app on your Mac, do any of the following:
Reorder albums within a folder: Drag the items up or down in the sidebar.
Move an album to another folder: Drag the album to a different folder in the sidebar.
Remove an album from a folder: Control-click the album in the sidebar, then choose Move Album Out Of [folder name].
Delete a folder from the sidebar
In the Photos app on your Mac, click My Albums in the sidebar.
Control-click the folder, choose Delete Folder, then click Delete.
The folder and the albums within it are removed from the library and from iCloud, but the items remain in your photo library. If you accidentally remove a folder, choose Edit > Undo Delete Folder to restore it.
