Hi Moe CBF,
First of all welcome to mac world..I hope you'll enjoy it..
Secondly, your problem is typing in Arabic.. Don't worry it's not a problem..
before anything you should know that mac has three arrangement styles to type in Arabic:
1- Arabic-PC the keyboard is the same as windows
2- Mac style many letters has been changed to be in better places
3- Arabic-QWERTY totally different from windows style
* Now how you can write in Arabic.
1- go to system preference
2- choose International
3- choose Input Menu
4- from there check mark the languages that you want from the list.
you can choose one of the Arabic styles or two or all of them.
That's it
but one more thing to swich between languages that you have chosen you can find an Icon next to the clock.
or you can use command+space to switch between the last two languages you have used before...
I hope it's clear..I know it's long but I wanted to make shore that you can understand easily...
anyway if there is anything you didn't uderstand let me know, I'll explain it again..
your sincerely,
albarq
