Fixed Arabic - PC keyboard layout for OS X
For some reason, the "Arabic - PC" keyboard layout in Mac OS X 10.4 and above is missing the letter thal ( ذ ) and the diacritic shadda ( ّ ). On standard Arabic PC keyboard layouts these are assigned to the tilde key to the left of the number 1, but OS X replaced the key with a comma.
Install this keyboard layout to restore the missing thal and shadda.
- Copy both
- Go to System Preferences > Language & Text > Input Sources.
- At the bottom of the list of keyboard layouts you should see one titled "العربي".
- Select it and type away!
