I have a problem writing in Arabic in my MacBook in Microsoft office in particular. What should I do?

What should I do?

1) You should be more specific as to the exact nature of the problem.

2) You should check if your computer is really running Mac OS 10.3 or lower because that's the forum to which you posted.

3) You should ask on a forum dealing with Microsoft software questions (probably on a Microsoft help forum). Make sure you say which version of Office you are using.
