Manage safety settings in Messages
In the Messages app 
, you can send text messages in two different ways:
Over Wi-Fi or cellular service, using iMessage with others who also use iMessage on an iPhone, iPad, or Mac. Your iMessage texts appear in blue bubbles.
With SMS/MMS messages forwarded from your iPhone to other devices. Your SMS/MMS messages appear in green bubbles.
You can use iMessage to send messages, photos, or videos to another iPhone, iPad, or Mac over Wi-Fi or cellular networks. These messages are always encrypted and appear in blue text bubbles on your iPhone, iPad, and Mac.

on your Mac, choose Messages > Settings, then click iMessage.Click Settings, then deselect Enable Messages in iCloud.
Choose one of the following:

Disable This Device: Turns off Messages in iCloud on your Mac only. Messages on your Mac are no longer stored in iCloud; on any other device where Messages in iCloud is turned on, messages continue to be stored in iCloud.
Turn iMessage on and off
iMessage uses end-to-end encryption, protecting your messages across all of your devices so they can’t be accessed without your passcode by anyone, including Apple. Because iMessage conversations take place over Wi-Fi and cellular networks, information related to the person you message doesn’t appear on your phone bill. iMessages can be backed up, so that if your device is lost or stolen, you can still reproduce important message threads.
Important: For Messages to be saved to iCloud, you must have enabled backup. If you haven’t, your messages won’t be restored. See Set up iCloud for Messages on all your devices in the iCloud User Guide.
When iMessage is on
You can send an iMessage using a Wi-Fi connection when you don’t have access to cellular service. The Recently Deleted feature saves deleted messages for up to 30 days, so if you’re concerned someone may have deleted messages from your device, those messages may still be in this tab.
When iMessage is off
When iMessage is turned off, features like message editing, message unsend, and read receipts aren’t available. Messages are sent using SMS/MMS instead.
Important: When using SMS/MMS, records of these messages may appear in your phone bill and those message records may be released through the cellular provider to the account owner for that phone number.
On your iPhone or iPad: Go to Settings
> Messages, then turn iMessage on or off.On your Mac with macOS 13 or later: Open Messages
choose Messages > Settings, click iMessage, then click Sign out. Confirm you want to sign out, then click Sign out again.On your Mac with macOS 12 or earlier: Open Messages
choose Messages > Settings, click iMessage, then click Sign out. Confirm you want to sign out, then click Sign out again.
Turn read receipts on and off
iMessage read receipts let iMessage users know when their messages have been read. With read receipts on, the person who sent you the iMessage gets a Read indicator below the message after you’ve read it. With read receipts off, they see only that the message has been delivered.
You have the option to send read receipts for all conversations, or only for individual ones. If you’ve turned on read receipts for all conversations, you can still turn them off for individual ones—and vice versa.
Note: Read receipts aren’t supported with SMS messaging and with group texts.
