Assamese Phonetic Keyboard for Mac OS

** First make sure your Mac has Unicode enabled Assamese font. I have used fonts from Ekushe, which somewhat satisfies the requirements but they have issues with showing up juktakhars containing Assamese "ra". Test your Mac's unicode capability by visiting www.xobdo.org or www.xophura.org to check that the Assamese contents are being displayed correctly. 
** Once you have a working font for Assamese set up in your Mac, proceed installing this Keyboard.

STEP1: Download the Assamese-Xobdo.keylayout file. It contains a keyboard Layout file and a Icon file. Unzip the file and extract both these files.

STEP2: You need to place the both the keylayout and Icon files in the "Library/Keyboard Layouts" folder. If you want to use it only for your user account, place it under your user home (~/Library/Keyboard Layouts). If you want to make it available to anybody working in your Mac then place it under system home (/Library/Keyboard Layouts ).

STEP3: Log off the computer or restart it. And log in back to your Mac
STEP4: Setup Input:
a. Open your Mac's "System Preferences" then go to "Language & Text" (for older mac it might be named as "International").

b. Click the Input Menu tab.

c. Scroll down until you find the name "Assamese-Xobdo" (or you may type Assamese in the search box).

d. Select the checkbox against "Assamese-Xobdo". The layout is now ready to use.

: To access the key layout, click on the flag at the top right corner of your screen. Select the keyboard layout from the list.
