Input source language keeps changing on Mac OS X 10.9.4

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.

Create a new account in the Users & Groups preference pane, 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, 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.

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

~/Library/Preferences/com.apple.HIToolbox.plist

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

Services ▹ Show Info in Finder (or just Show Info)

from the contextual menu.* An Info dialog should open.

☞ Does the dialog show "You can read and write" in the Sharing & Permissions section?

☞ In the General section, is the box labeled Locked checked?

☞ What is the Modified date?

If you don't have read and write access to the item, change the settings as directed here. Note, however, that if one file has wrong access settings, most likely others do as well. If the item is locked, unlock it.

*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. Open a TextEdit window and paste into it (command-V). Select the line you just pasted and continue as above.

Hi.

I do have the same problem as gaeluirbeach with Mavericks 10.9.4 on my MacBookPro : each time we come to the starting window (the one where we choose among the users accounts for opening a session), the language is by default French of France instead of French Canadian (CSA).

As you probably know, the keyboard in Canada is a QWERTY one, which isn't the case in France. So we have to change the keyboard attribution before logging.
This bug never happened with previous versions of Mavericks, nor with previous systems; it doesn't happen neither on my iMac (with Mavericks 10.9.4).
For sure, we made localizations on each account through the System Preferences -> Keyboard -> Advanced, to have Canada measurements, etc. as environment.

Bizarrely, this wrong by default choice of keyboard at starting up does not occur when starting with alt-key ; the logging is then interpreted correctly as being coded on by a CSA keyboard (because it works) and after opening the safety Mavericks partition, the CSA icon keyboard appears in the menu bar (along with the USA keyboard as the other favorite one). I chose Utility Disk and made disk and permissions reparations, but the bug still remains when I restart the MacBookPro (without alt-key).

So I followed the steps described above by Linc Davis (mainly suppressing items activated when opening a session) but the bug still remains.

Thanks for reading and help.

Well, I actually resolved this problem in the following way.

First, this problem of language when booting didn't occur on my two other iMacs (both running 9.4), only on my MacBookPro.
Second, MacBookPro had a problem when Mavericks was updated from 9.3 to 9.4 : on one of the accounts, some Apple apps were no more activable (Preview, iPhoto, iTunes). Strange, isn't it? So I had to create a new account with the personal folders...
All this to point out there had been problems when installing 9.4 on MacBookPro.

How I finally resolved ?
I re-installed 9.4 (alt-R on restart) and now, 10 hours later, everything seems OK : good localization when booting and switching accounts, all the apps seems to run fine everywhere...

' Hope it will work for you too !

You think mine is also a bug?

It's certainly a bug, though in just what is not clear.

There is an apple place up the road from me that do repairs and the like, think my best bet is just to bring it in?

I'd be surprised if that availed anything.

Hi guys, I've got the same problem.

I've tried reinstalling (twice), and for one or two weeks it looked like it was finally fixed, but now it started to do it again.

That means that every time I turn on my MacBook (mid 2009, Mavericks) I have to reinstall the 5 input sources I regularly use.

I had to reinstall twice, because the first reinstall didn't solve the problem. The second one lasted, as I said, about two weeks.

Also, on my second reinstall I selected the input sources right during Mac Os X install, so even before the Os was actually installed.

I was hoping that it was fixed once and for all, but now I see that the problem persists. I really hope Apple fixes it, it's becoming annoying.

In short, reinstalling didn't really fix it for me, except for a short time only.

Hi, GMC.

I'm sorry these re-installations didn't work for you.

My re-installation of Mavericks 9.4 three weeks ago still works well; and what about you, Gaeluirbeach?

But, GMC, do we talk of the same problem? What do you mean by « I have to reinstall the 5 input sources I regularly use » ?

Gaeluirbeach and I were concerned about the keyboard being proposed by MacOS when starting a new session;
do you really mean you need to use 5 different localized keyboards?

Yes, I do. I do use five input languages: Italian (which is the original language of the MacBook keyboard), Hebrew, Arabic, Greek polytonic and U.S. extended which has different diacritical signs I use for other languages written in the latin alphabet such as German and Polish.

Everything used to work perfectly in Leopard and Snow Leopard, but since I upgraded to Mavericks, every now and then the system only presents the U.S. (not even extended) input source, and that's when I have to reinstall all of them again, and remove the default, non-extended one.

It's a small annoyance but an annoyance nonetheless.

I usually have my MacBook connected with an external mouse, keyboard and monitor.

The only thing that changed in the last weeks is that yesterday i used my computer alone, disconnected from all external peripherals, and today I had this problem again, after weeks.

Maybe it's just a coincidence, but disconnecting the external keyboard is the only thing I did recently that could be vaguely related to input sources, and something I never did while the whole thing was working fine.

Correlation doesn't imply causation, but I'm out of ideas right now. Reinstalling didn't work, and neither did other solutions I found on the Internet.
