Mac Tags: Check Messages Without Encrypting

This guide shows you how to inspect the tags (metadata labels) attached to your macOS messages and files without turning on encryption. You’ll learn to view tags in Finder, Mail, and Notes, and how to verify that your messages remain unencrypted while still using tags for organization. No special tools are needed—just a Mac running a recent version of macOS.

What You’ll Need

• A Mac with macOS Catalina (10.15) or later
• Access to Finder, Mail, or Notes (depending on where your messages are)
• Messages or files that already have tags applied (or you can create new ones)

Step-by-Step

1. Check tags in Finder (for files and folders):
   1. Open a Finder window and navigate to the file or folder you want to check.
   2. Right-click (or Control-click) the item and select Get Info from the context menu.
   3. In the Info window, look for the Tags section near the top. You’ll see any colored dots or tag names applied to the item.
   4. To see tags without opening Get Info, switch Finder to List view (View > as List) and click the Tags column header if it’s visible. If not, right-click the column header row and check Tags.
2. Check tags in Mail (for email messages):
   1. Open the Mail app and select one or more messages in your inbox or a folder.
   2. Look at the top of the message list—you’ll see small colored dots next to messages that have tags. The tag name appears when you hover over the dot.
   3. To see all tags at a glance, click the View menu, choose Columns, and enable Tags. This adds a Tags column to the message list.
   4. To check a specific message’s tags, select it and press Command+I (or right-click and choose View > Message Info). The Info panel shows the tags applied.
3. Check tags in Notes (for notes):
   1. Open the Notes app and select a note from the sidebar or list.
   2. Look at the bottom of the note window—you’ll see any tags displayed as small labels (e.g., #work, #ideas).
   3. To see all notes with a specific tag, click the tag name in the sidebar under Tags. This filters your notes without changing their encryption status.
4. Verify that messages are not encrypted:
   1. In Mail, if you’re using an account that supports encryption (like iCloud Mail), check the message header. Encrypted messages show a lock icon next to the sender or in the header area.
   2. In Notes, encrypted notes are locked and show a padlock icon in the note list. If you don’t see a padlock, the note is not encrypted.
   3. For files in Finder, encryption is not applied at the file level by default—it’s usually whole-disk encryption (FileVault). To check if FileVault is on, go to System Settings > Privacy & Security > FileVault. If it’s off, your files are not encrypted at rest.
5. Add or remove tags without encrypting:
   1. In Finder, select a file and press Command+I, then click the Tags field and type a new tag or select an existing one. This does not encrypt the file.
   2. In Mail, right-click a message and choose Color Tags to assign a color tag. This only adds metadata—it does not encrypt the email.
   3. In Notes, type a hashtag (e.g., #project) anywhere in the note to tag it. The note remains unencrypted unless you explicitly lock it.

Common Mistakes

• Confusing tags with encryption: Tags are just labels—they don’t protect content. Many users assume a colored dot means the message is secure. It isn’t.
• Looking in the wrong place: Tags in Mail are not in the same spot as in Finder. In Mail, they’re in the message list or Info panel, not in the message body.
• Expecting tags to show in the message body: Tags are metadata, so they appear in the interface, not inside the text of the email or note.
• Assuming Notes tags are encrypted: A tag in Notes is just a label. If you want encryption, you must lock the note separately (File > Lock Note).

Tips

• Use consistent tag names (e.g., #work, #personal) to make filtering easier.
• In Finder, you can create smart folders that group items by tag, making it easy to find all tagged files without affecting their encryption status.
• In Mail, you can set up rules to automatically apply tags to incoming messages based on sender or subject—again, this doesn’t encrypt them.
• If you need to send an encrypted email, use the built-in Encrypt button in Mail (available for iCloud Mail with an Apple ID). Tags will still be visible to you, but the content is protected.

Troubleshooting

• Tags not showing in Finder column: Right-click the column header row in List view and ensure Tags is checked. If you’re in Icon view, you won’t see columns—switch to List view.
• Mail doesn’t show a Tags column: Go to View > Columns > Tags to enable it. If you still don’t see it, restart Mail.
• Notes tags not appearing in sidebar: Make sure you’re using iCloud Notes. Tags only work with iCloud accounts. Go to Notes > Preferences and check your account settings.
• Can’t see tags on a message you received: Tags are local to your Mac—they don’t travel with the message. You can only see tags you’ve applied yourself, not ones sent by others.
• Encryption icon appears unexpectedly: If you see a lock icon in Mail, it might be because the sender used S/MIME or your account has encryption enabled. This is separate from tags. To disable encryption for outgoing messages, go to Mail > Preferences > Accounts, select your account, and uncheck Use for encrypted messages.

Frequently Asked Questions

1. Do tags encrypt my messages? No, tags are just labels. They don’t provide any security or encryption.
2. Can I see tags on messages I receive? Only if you’ve applied tags to them yourself. Tags are local metadata, not part of the message content.
3. Will tags slow down my Mac? No, tags are lightweight metadata and have no noticeable performance impact.
4. Can I use tags to search for messages? Yes, in Mail you can search for a tag by typing tag:work in the search field. In Finder, use the search bar and select Tags as the search criteria.
5. Do tags sync across devices? Yes, if you use iCloud Drive for files and iCloud for Mail and Notes, tags sync across your Mac, iPhone, and iPad.
6. How do I remove a tag without deleting the message? Right-click the item, choose Get Info (Finder) or View > Message Info (Mail), and delete the tag name. In Notes, just delete the hashtag text.
