For some time now, about ½ the messages I try to send on my desktop Mac, won't send. But when I try to send them on my iPhone, they go through perfectly. On the desktop it says "not delivered" in red and "message send failure."
Both units are signed into the same icloud account. I've logged out of it and logged back in, nothing seems to fix it.
Help!
Monterey 12.4

Normally, logging out and logging in with Messages on the Mac resolves this. Be sure that your are logged in first on your phone, then log in on your Mac both for your Apple ID in System Preferences, and then inside Messages Preferences.
Here is a checklist, it should work if this is all showing as correct after logging out and back in as indicated above:
iMessage checklist
iPhone and Mac both logged in to same Apple ID. Try logging off and logging on if necessary.
iPhone Settings => Messages shows iMessage as "on" (sometimes toggling this off and then on fixes some things)
iPhone Settings => Messages shows Send & Receive showing both phone number and email (Apple ID)
iPhone Settings => Messages shows Text Message Forwarding and your Mac is listed and shown as "on" there.
iPhone Settings => Messages shows Send as SMS "on" and MMS Messaging and Group Messaging both "on"
On the Mac: Messages => Preferences shows same and correct Apple ID and "You can be reached for messages at" indicates both phone number and Apple ID (email), and "start new conversations from" indicates the phone number.
* Don't see the Text Message Forwarding setting on your iPhone? Go to Settings > Messages, turn off iMessage, turn it back on, tap Send & Receive, tap Use Your Apple ID for iMessage, then sign in with the same Apple ID used on your other devices.

Why can't I send messages on my desktop but I can on my iPhone?
