MacBook (OS X 10.6): how to change US English keyboard layout back to normal

Question

I'm using a MacBook with Snow Leopard. For some reason, I have accidentally enabled Japanese keyboard support (Kotoeri). Now, having disabled it, I face the following problem: My US English keyboard layout has changed.

The keyboard viewer displays some Japanese keys next to command, and in general the keyboard does not look like mine. In addition, some punctuation characters have moved to different keys, and some to inexistent keys.

Just to illustrate: The Yen sign appears now on the left of the Backspace, the underscore sign has moved to an inexistent key between Forward Slash and Right Shift keys. And there are more changes like that. The keyboard layout is set to US English.

I have tried Ukelele utility, but it only allows to remap existing keys, not to change them.

How can I roll back this layout to factory default?

Solution 1

Upgrading to MacOS 10.8 has solved the problem.

Solution 2

A solution that helped in my case: I installed KeyRemap4MacBook, and enabled 1 setting:

• Use US Keyboard layout

Now the keyboard works normally. The keyboard viewer, however, displays the Japanese keyboard until I click a key, then it shows a normal US keyboard.

Still it is a hack, and I will look for a solution that eliminates the problem completely.

So what's currently selected in System Preferences → Language & Text → Input Sources?

Enabled keyboards: US English, Russian, Keyboard and Character viewer.

As far as I read it, the OP has already changed the keyboard layout back to US English.

Thanks for the reply, but this does not revert the key mapping on the English keyboard back to English, it still stays Japanese-English, with the Yen sign on top and underscore sign on a non-existent key between Right Shift and Forward Slash keys

The keyboard layout in my case is same as here [link]superuser.com/questions/314783/…

[TimSparrow]

The solution suggested in that thread does not help

@Tim Did you try the solutions there?

[TimSparrow]

Yes, but neither helped. The layout is stuck to that pseudo-Japanese.

Switched to Australian kbd as a temporary fixup. This fixes most, but not all remappings.

Still does not work: there is no 'Change Keyboard Type' button on the Keyboard preference pane, and manual invocation of Keyboard setup assistant produced the following result: System/Library/CoreServices/KeyboardSetupAssistant.app/Conte‌​nts/MacOS/KeyboardSe‌​tupAssistant ; exit; 2012-03-02 17:53:46.409 KeyboardSetupAssistant[277:903] No unknown keyboard connected - terminating logout
