my i message doesn't work

Hi mpearson_,

Welcome to the Apple Community,

where some of us do our best to help each other troubleshoot.

Wondering if you are using Mac, PC, or another device,

and

Which operating system you have installed ...

and

if your software up-to-date.

and

if you have enough free space in Messages, for smooth operation of the app.

Also:

IF you have changed your Apple ID or Apple ID password recently,

you may need to update your sign-in info. on iMessage.

This article (link below) from Apple support may help

If you can't sign in to your iMessage account or FaceTime on Mac,

(Resetting NVRAM, (or turning off third-party apps) has worked for some who have experienced a similar issue)

There is a "Get Support" link to Apple at top right on this discussion page.

Hope something here is helpful :-)

Welcome to the Apple Community,

Wondering if you have enough memory / storage free (at least 50 Gb) for your Mac to operate smoothly.
