When you try to send a message in macOS’ Messages app, you may occasionally encounter the following error:

“There was an error sending the previous message. Would you like to send it again?”

However, sometimes this error may pop up seemingly out of nowhere, including when you’ve just rebooted your Mac, or brought it out of a sleep state – scenarios where you know you didn’t recently try to send a message.

While you could just hit the ‘Ignore’ button, most of the time this error will reappear almost immediately, and hitting ‘Resend Message’ when you suspect this error isn’t related to a sending failure could result in you resending message(s) that have already been successfully received.

If you’re encountering this error and are convinced that it isn’t due to a message failing to send, then there’s a few possible fixes you can try:

1. Check whether Apple services are down
2. Check you’re logged in
3. Force Quit
4. Setup Text Forwarding
