What languages does Mac OSX support

Going through Apple's knowledge base I could not find a "complete" list of Leopards international languages.

Macintosh: Languages Available for Apple's Localized Keyboards

Mac OS X: Displaying menus and dialogs in different languages

About input methods for different languages

The languages I use on a daily basis for my job are Hebrew, Arabic, Swahili, Persian, Icelandic, Kalaallisut which is also known as Greenlandic, Yoruba, Hausa, Dholuo, Zarma and Oromo. Does it support even half of them if not its a no go because I need to be able to use them at any time.

OS X can support almost any language available in Unicode, but for some you might need to add a font or keyboard layout. See this page:

Making custom keyboards is easy with Ukelele:

PS For Yoruba and Hausa, see these notes:

PSS Note that MS Word for Mac cannot do RTL scripts like Arabic/Hebrew/Persian.

While those languages do appear in System Preferences/International/Languages, OS X does not come with support for all of them. Support requires an appropriate font and a keyboard layout, so that you can read and type text. Examples of languages for which these are missing (and therefore must be found elsewhere, if they are available) include:

115 Amharic
121 Assamese
122 Bengali
125 Oriya
127 Telugu
128 Kannada
129 Malayalam
130 Sinhalese
132 Lao
135 Burmese
136 Khmer

OS X can also support various languages not on the list in System Preferences, such as Coptic, Syriac, Tifinagh, Sumerian, Akkadian, Ogham, Runic, Gothic, and Etruscan, as long as they have been encoded in Unicode and a font/keyboard has been installed.
