This could be a complicated problem to solve, as there are many possible causes for it. Test after taking each of the following steps that you haven't already tried. Back up all data before making any changes.

Before proceeding, test on another network, if possible. That could be a public Wi-Fi hotspot, if your computer is portable, or a cellular network if you have a mobile device that can share its Internet connection. If you find that iMessage works on the other network, the problem is in your network or at your ISP, not in your computer.

Step 1

Check the status of the service. If the service is down, wait for it to come back up. There may be a localized outage, even if the status indicator is green.

Step 2

Sign out of iMessage and FaceTime on all your Apple devices. Log out and log back in. Try again to sign in.

Step 3

Restart your router and your broadband device, if they're separate. You may have to skip this step if you don't control those devices.

Step 4

Follow these instructions to display the machine's serial number. If the number is missing or invalid according to this web form, take the machine to an Apple Store or other authorized service center to have the problem corrected.

Step 5

Take the steps suggested in this support article. If you don't understand some of the steps or can't carry them out, ask for guidance.

Step 6

From the menu bar, select

System Preferences... Network

If the preference pane is locked, click the lock icon in the lower left corner and enter your password to unlock it. Then click the Advanced button and select the Proxies tab. If the box marked SOCKS Proxy is checked, uncheck it. You don’t need to change any other settings in the window. Click OK and then Apply. Test.

The result may be that you can't connect to the Internet at all. Revert the change if that happens, or if iMessage still doesn't work. Remember that you must Apply any changes you make in the preference pane before they take effect.

Step 7

Select from the menu bar

 ▹ System Preferences… ▹ Flash Player Storage

and click

Block all sites from storing information on this computer

Close the preference pane.

Step 8

Make sure you know the ID and password you use with iMessage. Launch the Keychain Access application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad and start typing the name.

Use the search box in the toolbar of the Keychain Access window to find and delete all items with "iMessage" or "com.apple.idms" in the name. Log out and log back in.

Step 9

Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”

While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.

Test while logged in as Guest. After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.

*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.

If iMessage worked in the guest account, stop here and post your results.

Step 10

Start up in safe mode and log in to the account with the problem.

Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.

Safe mode is much slower to start and run than normal, with limited graphics performance, and some things won’t work at all, including sound outputand Wi-Fi on certain models. The next normal startup may also be somewhat slow.

The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.

Test while in safe mode. After testing, restart as usual (i.e., not in safe mode) and test again.

If iMessage worked in safe mode, but still doesn't work when you restart in "normal" mode, stop here and post your results.

Step 11

Triple-click anywhere in the line below on this page to select it:

/Library/Preferences/com.apple.apsd.plist

Right-click or control-click the highlighted line and select

Services Reveal in Finder (or just Reveal)

from the contextual menu.* A folder should open with an item selected. Move the selected item to the Trash. You may be prompted for your administrator login password. Restart the computer and empty the Trash.

*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select

Go Go to Folder...

from the menu bar and paste into the box that opens by pressing command-V. You may not see what you pasted because a line break is included. Press return.

Step 12

Reset theNVRAM.

Step 13

Reset the System Management Controller (SMC).

Step 14

Reinstall OS X.

Step 15

If none of the above steps resolves the issue, make a "Genius" appointment at an Apple Store, or contact Apple Support. When you set up a support call, select "Apple ID" as the product you need help with, not the hardware model. That way, if you're not under AppleCare, you may be able to talk your way out of being charged for the call.

Launch the Console application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad and start typing the name.

The title of the Console window should be All Messages. If it isn't, select

SYSTEM LOG QUERIES ▹ All Messages

from the log list on the left. If you don't see that list, select

View ▹ Show Log List

from the menu bar at the top of the screen.

Click the Clear Display icon in the toolbar. Then take an action that isn't working the way you expect. Select any lines that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.

The log contains a vast amount of information, almost all of which is irrelevant to solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.

Please don't indiscriminately dump thousands of lines from the log into this discussion.

Please don't post screenshots of log messages—post the text.

Some private information, such as your name or email address, may appear in the log. Anonymize before posting.

When you post the log extract, you might see an error message on the web page: "You have included content in your post that is not permitted," or "The message contains invalid characters." That's a bug in the forum software. Please post the text on Pastebin, then post a link here to the page you created.

This procedure is a diagnostic test. It makes no changes to your data.

Please triple-click anywhere in the line below on this page to select it:

launchctl print system | grep apsd | pbcopy

Copy the selected text to the Clipboard by pressing the key combination command-C.

Launch the built-in Terminal application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad and start typing the name.

Paste into the Terminal window by pressing the key combination command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.

Wait for a new line ending in a dollar sign ($) to appear below what you entered.

The output of the command will be automatically copied to the Clipboard. If the command produced no output, the Clipboard will be empty. Paste into a reply to this message.

The Terminal window doesn't show the output. Please don't copy anything from there.

If any personal information appears in the output, anonymize before posting, but don’t remove the context.

Some info: That may help

I am connect via Thunderbolt adapter to Ethernet cable directly to router/modem. (ethernet card stopped working) This has worked for the past year or more..

I tried adjusting my network locations, switching to wi-fi and that didn't change anything.

just a few moments ago. I added a new network location via Thunderbolt/Ethernet and it signed on for split second and booted me right off.

Step 2: logged out both iPad and iPhone out as well as iMac. Re-signed in on Mac only. Same error.

Step 9: I was able to log in as a guest user on iMac And sign into iMessage.

when I switch user back to my own, it automatically logs out of iMessage and I cannot sign in.

on the computer only. I can sign into iMessage on iPad and iPhone no problem

Sep 30, 2015 1:40 PM in response to Josh Komorowski

Back up all data.

Quit Messages if it’s running. Force quit if necessary. After each of the following steps, restart the computer and test. If the problem isn't resolved, quit again and go on to the next step.

Step 1

If you sync Contacts with a service such as iCloud or Google, disable the synchronization in the iCloud or Internet Accounts pane of System Preferences. When prompted to confirm, choose to delete the contacts from the Mac. They'll still be on the servers and on your other devices. Leave the preference pane open.

If Messages works now, re-enable Contacts synchronization, wait for the network contacts to reappear, and see what happens.

Step 2

Launch the Keychain Access application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad and start typing the name.

From the menu bar, select

Keychain Access Keychain First Aid

from the menu bar and repair the keychain.

Make sure you know the ID and password you use with iMessage.

From the Category list in the lower left corner of the window, select

All Items

Select the entire line below on this page and copy it to the Clipboard (command-C):

com.apple.idms

Paste (command-V) into the search box in the upper right corner of the Keychain Access window. Delete any items that appear in the search results.

Repeat with each of these lines:

iMessage ids:

Select

Keychain Access Preferences... Certificates

There are three menus in the window. Change the selection in the top two to Best attempt, and in the bottom one to CRL.

Quit Keychain Access. Log out and log back in.

Step 3

Hold down the option key and select

Go Library

from the Finder menu bar. Move the following items from the Library folder to the Trash (some may not exist):

Containers/com.apple.corerecents.recentsd

Caches/com.apple.Messages

Caches/com.apple.imfoundation.IMRemoteURLConnectionAgent

Containers/com.apple.iChat/Data/Library/Caches

Containers/com.apple.soagent

IdentityServices

Leave the Library folder open.

Step 4

Go back to the Finder and move the following item from the open Library folder to the Desktop:

Messages

Note: you are not moving the Messages application. You’re moving a folder named “Messages.”

If Messages now works, delete the Messages folder on the Desktop. Otherwise, quit Messages again. Put back the folder you moved, overwriting the newer one that may have been created in its place.

Step 5

In the Preferences subfolder, there may be several files having names that begin with any of the following strings:

com.apple.iChat

com.apple.ids

com.apple.imdsmsrecordstore

com.apple.imessage

com.apple.imservice

Move them all to the Desktop. There may also be a file with the name "com.apple.imagent.plist". Move that to the Trash.

Also in the Preferences folder, there's a subfolder named "ByHost". Open it and do the same thing.

Log out and log back in. Test again. This time Messages should perform normally, but your settings will be lost. You may be able to put back some of the files you moved to the Desktop in this step. Relaunch and test after each one. Eventually you should find one or more that causes Messages to malfunction. Delete those files and recreate whatever settings they contained.

If the issue is still not resolved, quit Messages again and put all the items you moved to the Desktop back where they were. You don’t need to replace the items you moved to the Trash. Stop here and post your results.

If you later decide that you don’t like the results of Steps 3 and 4, you can undo them completely by quitting Messages and restoring the items you deleted in those steps from your backup.

The only step 1-5. I could do was (1) sign out of iCloud. Now I cannot sign back in.

The files that you are referring to do not exist on my computer.


com.apple.idms

iMessage ids:

Containers/com.apple.corerecents.recentsd

Caches/com.apple.Messages

Caches/com.apple.imfoundation.IMRemoteURLConnectionAgent

Containers/com.apple.iChat/Data/Library/Caches

Containers/com.apple.soagent

IdentityServices

com.apple.iChat

com.apple.ids

com.apple.imdsmsrecordstore

com.apple.imessage

com.apple.imservice

This procedure is a diagnostic test. It makes no changes to your data.

Please triple-click anywhere in the line below on this page to select it:

ls -@Oaen L*/Cont* | pbcopy

Copy the selected text to the Clipboard by pressing the key combination command-C.

Launch the built-in Terminal application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad and start typing the name.

Paste into the Terminal window by pressing the key combination command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.

Wait for a new line ending in a dollar sign ($) to appear below what you entered.

The output of the command will be automatically copied to the Clipboard. If the command produced no output, the Clipboard will be empty. Paste into a reply to this message.

The Terminal window doesn't show the output. Please don't copy anything from there.

Could not sign in to iMessage an error occurred during activation. Try again
