iMessage constantly OFFLINE

Sign in with 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.​

Use Messages with your Mac

Make sure that your devices are set up as follows:

• Each device is signed in to iCloud with the same Apple ID.
• On iPhone, go to Settings > Messages > Send & Receive. Make sure that the Apple ID at the top of the screen is the same Apple ID that you're using for iMessage on your other devices. Add a check to your phone number and email address, so that you can be reached by iMessage at both. Do the same on your iPad or iPod touch.
• On iPhone, go to Settings > Messages > Text Message Forwarding, then choose which devices to allow to send and receive text messages from this iPhone. If you're using two-factor authentication for your Apple ID, a verification code appears on each of your other devices: enter that code on your iPhone.
• On Mac, open Messages, then choose Messages > Preferences. Click Accounts, then select your iMessage account. Make sure that the Apple ID shown here is the same Apple ID that you're using on your other devices. Add a check to your phone number and email address.

Use Continuity to connect your Mac, iPhone, iPad, iPod touch, and Apple Watch

I have no idea how or why, but I was signed out of my Apple ID in Messages. If this is also your issue, here's the solution:

• Open Messages > Preferences > Accounts
• Select the muted Apple ID / iMessage account that you use with your iPhone/iPad
• Enter your password
• VOILA! You should be back online

I FULLY agree that these "idiosyncrasies" are annoying and frustrating 😠. I'm a lifelong Apple user (first computer was the Macintosh), and I've been reading about Android of late. Apple has left me disappointed more than happy since Steve Jobs passed.

Hope this helps someone! 😀

If you have an iPhone, try going to SETTINGS - MESSAGES - TEXT MESSAGE FORWARDING - and make sure your Mac is selected. This resolved my problem and added my phone number to my listed accounts. I don't know why it lost that ability after it had worked seamlessly for a long time. 😕

I've signed out of iMessage and signed back in. I still show to be offline. I have not been able to send or receive an iMessage since October. I have tried signing out and back in several times to no avail. iMessage is working fine on my iPhone. The offline issue is solely with my mid-2011 iMac.

I have exactly the same issue.

I can send/receive texts and they appear on both my mac and iPhone, but iMessage shows as offline and I can't change it to any of the other options.

I followed the suggestions above, but no go.

After having no issues with message forwarding, receiving or responding since I got my computer 3 months ago, yesterday it suddenly started doing this very thing. Continually shows I'm "offline". Will not let me switch to available. I have double checked all my settings, which never changed in the first place and I still am unable to send messages from my Mac.

Beyond frustrating.

I just googled this issue which bought me here . I too cannot change my status from "Offline" to "Available" on my MacBook Pro , and from what ive read , no body else seems to of found a solution as yet .

Nope, doesn't work

All 3 of my iMessage accounts are selected and the Apple ID showing is correct.

I was hopeful of this resolution, but alas, no. Oddly enough, when I first log into my Macbook iMessage does pick up my last message, but then goes "offline". Issues still persists after updating to Sierra 10.13.3.

i have a macbook and this is not working for me. Ive even tried the Flash> storage >Block setting as well and it also does not work. I can send a text, I can receieve from the person I just sent but I am always marked as offline no matter how many times I change it to any of the other options

After working with an Apple technician today, I have a solution for this issue. I'm not sure if it will fix every instance, but my iMessage on both my Mac and AppleWatch are now working perfectly once more.

1. Close out of all other programs, including iMessage.

2. Go to System Preferences > Date & Time.

3. Click the lock in order to make changes. Then uncheck "Set date and time automatically" before rechecking it.

4. I would restart your computer at this point and then reopen iMessage.

This is what fixed my issues and was told that there is something with the date and time that were interfering with the imessage server, keeping it stuck in time. My iMessage still shows as "Offline" but this has not affected any of my messages sending.

I also have the same issue.

I can send and receive messages. I see them on my MacBook and iPhone, but iMessage shows that I am in “offline” status and I can't change it.

I followed the suggestions above, but it doesn't helped.

Does not work - i have many apple devices. I have continuity etc all on. I've even used the suggested automatic time preference options and have not had success. It RANDOMLY does this. I notice when I am texting non-imessage phones and utilizing the message forwarding options via my phone. It tells me at random that I cannot send this message. This is beyond frustrating.
