there is a convenient pashto input method on windows. but the pashto keyboard layout shipped with osx is different with it.

this one is very same with windows one.

How to use

1. download "Pashto For Mac.keylayout"
2. copy the file to one of the following locations:

    /Library/Keyboard Layouts/
    ~/Library/Keyboard Layouts/

3. Open International
4. check "Pashto For Mac" in Input Menu
5. restart osx

Limit

some special key functions will not be used in some application, just switch to other keyboard layout to use them

Editor

recommend "Text Edit", it support RTL very well, and both MS Office 08 and IWork 08 do not support RTL
