iMessage Not Working on Mac?

How to Fix iMessage Not Working on macOS?

iMessage usually works great, but sometimes issues can occur that prevent the app from working on macOS. Regular text messages need a cellular network to send messages, while iMessage requires an internet connection for the message to be sent.

iMessage not working on Mac

If you're having a Message sync problem, first, check if your Mac is connected to the internet. It can be wi-fi, ethernet, or personal hotspot. If everything is fine with your internet connection, see if all email addresses you want to use with iMessage are active. If not, check iMessage settings for both your Mac and iPhone or iPad and ensure the same number and email addresses are active.

Suppose your Mac doesn't receive messages while your other devices try sending a message from your Mac. Some users have reported that all past text messages appear after sending a message from their Apple computer. If you're experiencing other problems or the solutions above didn't help, look at the troubleshooting steps below.

3. Simultaneously, press the Command+Shift+G key to bring up the “Go To Folder” window.

Toggle iCloud Sign-In

Newer versions of macOS sync messages with iCloud, and sometimes it can cause problems to occur. The best-proven fix is signing out of iCloud completely, restart Mac, and then signing in to iCloud again. This usually helps Mac to reacquaint itself with the messaging server.

Before performing these steps, make sure all your iCloud files are backed up. Suppose you have Desktop and Document Sync enabled. In that case, I recommend downloading your documents and desktop files from iCloud and disabling that sync as your files can get a bit lost.

1. Click on the Apple logo in the menu bar.
2. Select “System Preferences”.

Mac System Preferences

3. Click on the “Apple ID” button.

Go to Apple ID

4. Select “Overview”.
5. And finally, click on the “Sign Out” button.

iCloud Sign Out

6. Restart Mac.
7. Sign in to iCloud again.

1. Click on the Apple logo in the menu bar.
2. Select “System Preferences”.

Message Forwarding Enabled on iPhone

If you’re trying to send a message from your iPhone to your Mac and the iMessage issue is that your text message does not show up on your Mac, make sure that you’ve enabled SMS text message forwarding and relay for iPhone and Mac. That way, Mac can relay SMS text messages to and from iPhone through Messages. If that feature is disabled, you will not send SMS text messages from your Mac to Android users.

Check If iMessage Works on iPhone/iPad

If you have other Apple devices such as an iPhone or an iPad, check that iMessage works on different devices. If other devices are also experiencing the same issue or showing “Waiting for activation error” or similar, there may be an issue with Apple iMessage servers being down.
