All Messages Conversations Suddenly Blank

Hi,

Does the "history" fill in if you send a new iMessage ?

What did you clean the Drive with and what was removed ?

Please read this whole message before doing anything.

This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.

Step 1

The purpose of this step is to determine whether the problem is localized to your user account.

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 documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; 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. Same problem?

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.

Step 2

The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.

Please take this step regardless of the results of Step 1.

Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.

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 software RAID, you can’t do this. Ask for further instructions.

Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and 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. Same problem?

After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

Hi,

Did you have any luck with the Tests that Linc suggested ?

Whilst opening Messages app and setting up with the same Apple ID in a guest of different Mac User account will tell us if the app works it will not show you the "missing" iMessages as they are sent once and cannot be retrieved again by the same device.

Using the Safe Mode to boot into will allow you to use your regular Mac User account which might give us more info.

Having said that the Different Users method may catch up on the very latest ones where time limits have not been exceeded.

This may "prove" that you have lost the ability to Write to the file that stores the iMessages you have received and displays them when the app is opened (if they have not been Dismissed or gives you the "history" when talking to a person again.

If the tests that Linc suggests do provide some insight and you can see some of the older iMessages then check the following:-

Navigate to ~/Library/Messages (Use the Finder > Go Menu whilst holding the ALT key down and then selecting the Library that appears.)

There are three db items in this Messages folder that you are interested in.

Right Click chat.db and then Select Get Info.

In the Info Panel scroll to the bottom where the Ownership an Permissions are listed.

Highlight your own shortname (Same name as on the Little House Icon folder).

This should list you have Read and Write Permissions.

At the same time you can now click the little Cogwheel type icon under the List.

If you Own it the wording should be greyed out and it should read "Make Name (Me) the Owner"

Repeat for the other two .db items (not the older incompatible ones you may have or the Attachments Folder)

Let us know of the situation up to this point.
