In my case it was even more difficult because the OS X partition became a 'read-only' partition (because of too many emergency shutdowns I did while desperately trying to boot OS X with a failed GPU) so I had to remove a hard drive from MacBook Pro and (using a USB to SATA 2.5' adapter taken from my portable HDD) attached it to a computer with. I didn’t have an issue on my older laptop and when I started using a newer laptop (MacBook Pro running Catalina – 10.15.4) this issue of not sending standard text messages started. I have gone through all of the steps backwards and forward and it doesn’t help.

1. The Messages app on my Macbook Pro (running High Sierra) suddenly stopped sending text messages to Android devices. I can still send texts to Android users from my iPhone without a problem, but when sending texts from the Messages app on my Macbook Pro it will not send to Android devices. It just started doing this out of the blue yesterday.
2. Sorry Dan, altering the date via terminal was a lost of time. It didn't work for me. What did work was using a bootable usb. In a friend's Mac, download the desired OS installer (High Sierra in my case for my MacBook Pro Late 2011 - google 'How to Download a Full macOS High Sierra Installer App') and create the bootable USB, HDD or even SSD with Disk Creator (2 steps very friendly freeware.
3. Keychain Access can occasionally bug out and create issues. This happens especially when you upgrade your macOS or switch to a new Mac. While the Migration Assistant is an amazing tool, we’ve seen that if you chose to defer dealing with Keychain Access, the Messages app sometimes stops working correctly.

Hi,

Why Wont My Messages Download On My Macbook Pro 2020

You need to replace the ~/Library/Messages info before proceeding.

That only holds the Chat.db items that in effect hold the record of the iMessages conversations.

If these are missing some chats/conversations will be blank and also no 'History' will be shown if you connect to someone you previously chatted with.

Saved Chats are in ~/Library/Containers/com.apple.iChat/Data/Library/Messages which does the same things for non iMessages chats. Both types are stored there but the History part works for non iMessages ones.

Check this.

On the iPhone > Settings > Messages > Send and Receive is the iPhone Number active ?

It should be greyed out but ticked.

Despite it being unchangeable by the User I have twice seen the number Unticked and found it does not sync properly.

If this is the case Removes the Apple ID.

Deselect Messages being ON and active.

Then place the iPhone in Airplane mode for a few minutes.

Then go back to the Messages Settings and Enable the app.

Wait for it to verify the iPhone Number.

Check it will send an iMessages to the Apple ID (Mac)

Reply from the Mac.

If this works add the Apple ID back to the settings on the iPhone.

Accept the pop up on the Mac when it appears about the Info the iPhone is Using.

Reset Text Forwarding if required.

With Messages for Mac, you can send unlimited messages to any Mac, iPhone, iPad, or iPod touch that uses iMessage, Apple's secure-messaging service. iPhone owners can use it for SMS and MMS messages, too.

Set up iMessage

iMessage is the Apple messaging service you get automatically with your Apple ID.If Messages asks you to sign in, use the same Apple ID that you use with Messages on your iPhone and other devices. It's usually the same Apple ID that you use for iCloud, the iTunes Store, the App Store, and the account you created when you first set up your Mac.

Learn what to do if you get an error when trying to sign in to iMessage.

Have a conversation

1. Click the New Message button at the top of the Messages window.
   
2. Type the recipient's name, email address, or phone number, or click and choose a recipient. If they're in your Contacts app, Messages finds them as you type. To start a group conversation, just add more recipients.
   
3. Type your message in the field at the bottom of the window, then press Return to send it.
   • To include emoji, click .
   • To include an image or other file, just drag or paste it into the message field.

   • To add other items, such as Memoji stickers, GIFs, and message effects, click the apps button .
4. After starting a conversation, click the Information button (or Details) in the upper-right corner of the window to take actions such as these:
   • Use FaceTime to start an audio call or video call .

New in macOS Big Sur

macOS Big Sur introduces new features to improve conversations:

• Pin a conversation to the top of the conversation list so that you can quickly get to it. Just Control-click the conversation to open a shortcut menu, then choose Pin.
• Help bring your message to the attention of a group member: Either click their name after you type it, or include the @ symbol before their name: “@Jocelyn, see you then!” When you mention someone, their name is highlighted in the message, and they will receive a notification letting them know they’ve been mentioned.

Add a tapback to a message

A Tapback is a quick response that expresses what you think about a message, such as that you like it or think it's funny. Your Tapback is visible to everyone in the conversation who is using iMessage.
