• Microsoft Office 2008 for Mac : fails miserably on some rtl unicode hebrew chars outside of 0x05D0-0x05EA range ; total #fail...
  • Apple Pages '09 : handles beautifully all unicode hebraic chars and diacritics but fails justifying the last line of paragraphs... It always justifies it as if it were ltr and not rtl ! It's amazing to discover it can do vertical text and not correct rtl !
  • OpenOffice : no problem so far, everything woks beautifully, including the most complex diacritics, justification, bullets, the whole thing.

Conclusion: OOo is not only your friend to write rtl documents on a mac, it's almost your only friend (almost because I did not test other less known editors that handle rtl beautifully).
