My sms service are working now 🙂 but if i read in the manual, it should be possible sending group sms. Just write the name of the group as an address, but i can't make it working??? anybody there can help?

This is just one of many problems I am having with Yosemite. In any event, I had two devices setup for Text Message Forwarding (this one and my MacBook Air). They both worked for a while, but neither one will work now. I just get the error “[phone number] is not registered with iMessage”. I unselected both devices, and reselected just this one. I re-entered the new code, and then tried to send the message again. Still no luck. I think Yosemite is the buggiest version of OS X I have ever seen.

😕

Mac mini (Mid 2011), Intel i7, 16 GB RAM, Yosemite 10.10.1

iPhone 6+, iOS 8.1.2

Actually, I have to clarify something here. I can still send SMS messages to friends (without an iPhone) who I've previously communicated with on iMessage. However, if I try to add a new cell number (non-iPhone), I get the error “[phone number] is not registered with iMessage”.

Hi,

There do seem to be some quirks about starting new SMS conversations as there is no way to tell the App that it needs to look at SMS as an option.

If you use the Name in the "to" spot as a Drop down the SMS ones are indicated as Text Messages as opposed to the normal blue iMessages indicator.

Numbers that have not been connected to tend to be unmarked with the blue indicator but list 'iMessages " as an option (my Land Line shows up like this).

I have yet to find a "Fix"

If you're still looking for a solution:

Check your messages setting on your iphone, where it says "Text Message Forwarding" , turn it on and then you'll have to enter a code that generates on your computer. Once you do that you may have to shut down and restart messages on computer, but you should be good send to everyone at that point.

Hey Mike... You are a Genius!! That was my problem... It's working now... after all the frustrations mentioned above... THANKS

I set this up back when I first upgraded to Yosemite and it worked great! Now all of a sudden, it gives me the " Not Registered With iMessage". Forwarding is on all my devices. Can't seem to figure out why it randomly stops working.

I have been getting it to work for short periods of time by logging out of messages, quitting and re-signing in... but this seems to only fix it for a few hours before it stops working again. Anyone know how I can avoid logging in and out several times a day? Thanks!

Hi,

It seems that some people are experiencing issues with Logging in fully to the iMessages Servers from their Mac.

There is one Error Messages that is seen that is known to be very similar.

This Error can only be fixed by Contacting Support.

What is does prove though is the The Apple ID in use can be rejected on a Device by device basis, i.e. it will work on a iOS device or even another Mac but not on one particular one.

Sometimes deleting the Keychain item for the iMessages Login can help (then Restarting the app)

It is called IDS: yourApple ID- Auth Token

If deleting this does not work try repairing the Keychain.

After that I would contact Apple Support. You may have to speak to a Level 2 person as Level 1 people try to fit everyone into Software or hardware issues and charge for Out of time Apple Care.

Fixing and Apple ID/Account is free.

This fixed my issue between my rMBP (10.10.2) and iPhone 6+ (8.1.3). Thanks!

Perfect - thank you!

This worked for me pwmmike. Even though my macbook was already selected, cycling it off and back on seems to have fixed the problem. Thanks!

pwmmike's good suggestion worked for me. THANKS!
