TL;DR
Select a message in its conversation and press Delete to remove that message.
- To remove a whole conversation, select it in the sidebar, Control-click it and choose Delete. Review the confirmation before accepting it.
- With Messages in iCloud enabled, deletion syncs across your devices, but not to the recipient’s copy.
- Save attachments first. Recently Deleted keeps messages up to 30 days unless you permanently delete them sooner.
You meant to clear one photo or an old thread, and the confirmation says it will be deleted from all your devices. Pause there if you may need it later.
Apple keeps deleted messages in Recently Deleted for up to 30 days, but permanent deletion can happen sooner, and Messages in iCloud syncs the change.
Here is how to remove just what you intend and check recovery first.
Before you delete: save what matters
Deleting a message only changes your copy. If you sent an iMessage by mistake, Undo Send may remove it from recipients’ devices when they use macOS 13, iOS 16, iPadOS 16.1, visionOS 1, or later.
You have up to two minutes. If a recipient uses macOS 12, iOS 15.6, iPadOS 15.6, or earlier, the original remains in their conversation and Messages notifies you that they may still see it.
Undo Send does not work for SMS, MMS, or RCS texts.
If a photo, video, or file matters, save it outside Messages before deleting. Apple’s current Messages guide shows how to find shared attachments.
Open the conversation, click the person or group name at the top, find the attachment under its category, and save or drag a copy to Photos or Finder.
Open that saved copy to confirm it works. A synced Messages library is not a separate archive, and a regular iCloud device backup does not include messages that are syncing through Messages in iCloud.
Also check the retention setting. In current macOS, choose Messages > Settings > General and look at Keep messages.
If it is set to 30 days or 1 year, conversations and attachments can be removed automatically after that period. Choose Forever if you want Messages to retain them. Older macOS versions call Settings “Preferences.”
Delete one message or attachment
In Messages, open the conversation and select the specific bubble, photo, video, file, link, or audio message in the transcript. Press Delete and confirm. You can select more than one item before pressing Delete.
This removes those selected items while leaving the conversation itself in your sidebar.
For a batch of attachments of the same type, open the conversation details by clicking the contact or group at the top.
Under a category such as Photos, choose Show more, select the items, Control-click the selection, and choose Delete. Review the selection before confirming.
Delete a whole conversation
To remove the entire thread, select it in the Messages sidebar, Control-click, and choose Delete. You can select several sidebar conversations and delete them together.
On a trackpad or Magic Mouse, Apple also documents swiping left with two fingers on a conversation and clicking the delete control.
The exact confirmation can differ with your macOS version and sync settings, so read it before proceeding.
Deleting a conversation removes its messages and attachments from your Messages view. It does not delete the recipient’s copy.
If Messages in iCloud is enabled, the deletion is applied to your other devices where Messages in iCloud is on.
Recover a message before it is gone for good
Open Messages and choose View > Recently Deleted. Select the conversation and click Recover. Apple’s current guide says items can be recovered for up to 30 days.
If they do not appear there, they may have aged out, been permanently deleted, or never synced to this device.
You can also remove an item from Recently Deleted before the 30 days end: select it there, choose Delete, and confirm. That is the irreversible step in the normal Messages interface.
Deleted items are removed from devices after 30 days and permanently deleted from iCloud after 40 days, according to Apple.
Do not treat that outer window as a promise that every message remains recoverable for the full period. Manual permanent deletion can end recovery sooner.
What a backup can and cannot do
Time Machine is useful for keeping older Mac files, but Apple’s general backup guide does not promise that a particular Messages conversation can be restored from every backup.
Do not erase Messages database files in Finder or run Terminal cleanup commands as a routine shortcut. They bypass the app’s recovery controls and can damage more data than the conversation you meant to remove.
Apple’s iCloud Backup guide says messages are included in iCloud Backup when Messages in iCloud is off.
When Messages in iCloud is on, messages sync separately and are not included in the daily iCloud device backup.
That means an older iPhone or iPad backup is not a dependable second copy for messages that were syncing through Messages in iCloud.
For important material, save individual attachments or preserve the information in another readable form before deletion, then open the saved copy to verify it.
Frequently asked questions
Can I delete one message without deleting the whole conversation?
Yes. Open the conversation, select the message or attachment in the transcript, press Delete, then confirm. The rest of the conversation stays.
To remove the whole thread, select it in the sidebar and choose Delete.
Does deleting a message on my Mac delete it from my iPhone?
If Messages in iCloud is on for both devices, deleting a message or conversation on one removes it from your other devices using the feature.
It affects your copies, not the recipient’s. If syncing is off or a device is offline, check its state before assuming the change has reached it.
Can I get a deleted message back on a Mac?
Open Messages and choose View > Recently Deleted. Select the conversation and choose Recover. Eligible items can remain recoverable for up to 30 days.
Deleting an item from Recently Deleted permanently removes it and cannot be undone. Check that you no longer need it before choosing Delete.
How do I permanently delete messages before 30 days?
In Messages, choose View > Recently Deleted, select the conversation and click Delete. Confirm only after checking that you no longer need that conversation.
Why did my messages disappear after I changed Keep Messages?
In Messages, open Messages > Settings > General and check Keep messages.
Choosing 30 days or 1 year allows older conversations and their attachments to be removed automatically.
Set it to Forever if you want to keep them in Messages, then recover eligible items in Recently Deleted if they are still there.
Will an iCloud backup restore messages deleted from Messages in iCloud?
Apple says messages that sync through Messages in iCloud are not included in the daily iCloud device backup.
A device backup therefore is not a reliable way to restore those synced messages.
If the messages matter, check Recently Deleted and make a separate copy of important attachments before deleting. Do not assume a backup contains a second copy.
