Share an iCloud Drive Folder From Finder on Mac

Emailing versions of files back and forth is how documents grow names like final-v7-REALLY-final.docx. If the files live in iCloud Drive, share the whole folder instead: everyone sees the same contents, changes appear for all participants, and nobody attaches anything. Here's the full lifecycle — share, set permissions, manage people, stop cleanly.

Share the folder

1. In Finder, open iCloud Drive and find the folder. It must be in iCloud Drive — local-only folders and folders inside app containers can't be shared this way. (Drag a local folder into iCloud Drive first if needed; that moves it, so copy instead if you want a local original kept.)
2. Right-click it and choose Share.
3. In the share sheet, make sure the mode is Collaborate — not Send Copy. Send Copy mails a snapshot; Collaborate shares the living folder.
4. Click the options line beneath to set the two permissions that matter (next section).
5. Pick how to invite — Messages, Mail, or Copy Link — and send. Invitees click through, sign in with their Apple ID if required, and the folder is theirs to open.

The two permission choices

• Who can access: Only invited people means each participant signs in with their Apple ID, and forwarded links do nothing for outsiders. Anyone with the link turns the URL itself into the key — convenient, and exactly as leaky as it sounds.
• Permission: Can make changes lets participants add, edit, and delete files; View only lets them look and download. Deletions by an editor sync to everyone, so give edit rights the way you'd hand out house keys.

Defaults lean sensible — invited-only with editing — but check rather than assume, and prefer invited-only for anything you wouldn't pin to a noticeboard. Permissions are folder-wide: everyone you invite gets the same access to everything inside, subfolders included. If one document in the set deserves tighter rules, share that file separately with its own settings rather than fighting the folder.

Living with a shared folder

Participants who accept see the folder in their own iCloud Drive, marked with a shared-folder badge and people icon, and can also reach it from an iPhone or iPad via the Files app, or from a browser at iCloud.com — a Mac isn't required on their end. Changes sync to everyone continuously; there's no "publish" step. Two facts surprise people:

• Storage bills to the owner. The entire folder counts against the sharer's iCloud quota, not the participants' — sharing 40 GB of video costs your plan, and their quota is untouched.
• Deletion is deletion. When an editor deletes a file, it leaves the folder for everyone. As the owner you can usually fish it out of your Recently Deleted within 30 days; participants can't.

Manage people, change permissions, stop sharing

1. Right-click the shared folder and choose Manage Shared Folder.
2. From here you can add people, remove a participant, change an individual's permission between edit and view, or flip the who-can-access setting.
3. To end it entirely, click Stop Sharing. Participants lose access immediately; the folder and its contents remain intact in your iCloud Drive. Nothing of yours is deleted by stopping — undoing a share is exactly this safe, and you can re-share the same folder later if needed.

If a participant made local copies before you stopped sharing, those copies are theirs — stopping controls access to the live folder, not files people already downloaded. Share accordingly.

Sharing photos instead?

A shared folder works for image files, but Photos has purpose-built tools that handle it better — Shared Albums for casual sharing that costs no storage, or the Shared Photo Library for a household's whole collection.
