I can't send messages from my phone number on iMessage on OSX Mavericks

Hi,

Can I ask if you upgraded from something before OS X 10.8.2 ?

After this point you need the Serial Number to be present on the Logic/motherboard and readable by the System

Use the Apple Menu > About this Mac.

Then click twice on the Line that read the Current OS X version.

It will change to the Build number and then the Serial Number should be shown.

(Don't post it or a picture of it)

 MacBookPro 2Gb (Snow Leopard 10.6.8)
 Mac OS X (10.6.8),
 Couple of iPhones and an iPad

I did this and looked at the serial number. What is supposed to happen after I look at the serial number?

I don't recall what OS I upgraded from... I just do upgrades when they come available... not trying to be difficult!

HI,

If the Serial Number shows up then this is not your issue.

You can update to Mavericks from Lion and from Mountain Lion.

In Mountain Lion this means you could be anywhere between OS X 10.8(.0) and OS X 10.8.5

Messages was changed at the OS X 10.8.2 update to require that the Serial Number was present to use in the Auth Token that shows in the Keychain.

From earlier you posted:

I have switched to my gmail, @me, and icloud, and none can send or receive.

Is this your actual Apple ID and the @me.com iCloud link email you got followed by the @iCloud variant ?

Messages does treat these as Separate Apple IDs.

If my suggestion is correct which is being used on the iPhone at the moment ?

my phone has all these accounts on it, set to receive... and starting new conversations comes from my phone number.

Hi,

I would cut down the options on the iPhone possibly removing any Apple ID altogether (then placing in Airplane mode for Five Mins) before re-adding back just the Apple ID used on the Mac.

I had this exact problem after updating to Mavericks. My phone number was missing as an option in iMessage settings on my computer.

From the replies I figured out that my problem was that on my phone, I had my phone number enabled and checked, but I didn't have my apple id account enabled ( i was not signed in ). Once I signed into this account on my phone, I then went to my computer and logged back into iMessage and my phone number appeared.

I prefer to only use my phone number for iMessage on both devices, so at this point, I went into settings of both and unchecked the apple id email account as an option. Seems to be working now.

Thanks for the help!

This really helped me. I was really befuddled knowing that I'd see the phone number in there. Then you point me in the right direction to focus on the phone to get it going again. After turning iMessage on and off twice, the number popped back into iMessage on the iMac. Thanks ever so much.

I had this problem also. To cure it, I had to sign out of my Apple ID on all places on my phone, on my mac in FaceTime, Messages AND ICLOUD IN SYSTEM PREFERENCES. Quit Messages and FaceTime on my Mac, sign in again on the phone, then in System Preferences on my Mac and the phone number showed up in FaceTime & Messages.

Thank you so, so, so much. I spent more than an hour trying to solve this before I found your wonderful reply. Jan

You're welcome.

I had the same issue with my iPad.

They resolution I found was that the settings on the iPad were fine, when I checked on my phone it was set to send an receive from my number but it hadn't signed in with my Apple ID. When I signed it in on my phone it came up on my iPad asking if I wanted to add it.

My iPad was already signed in, but the number wasn't linked so it was pulling through.

worked like magic! thank you.

You're welcome too.
