Mitz Pettel has released The Hebrew Spelling Service for Mac OS X.
Offered as freeware under the GNU General Public License (GPL), the Hebrew Spelling Service adds a Hebrew dictionary to Mac OS X’s built-in spell checker. The software is based on Hspell, an open-source Hebrew spell checker.
Once the Hebrew Spelling Service is installed, it’s accessible from any Mac OS X application that has a Spelling submenu in its Edit menu, including Apple’s TextEdit and Mail applications and Mellel, the multilingual word processor from RedleX that supports right-to-left languages.
The Hebrew Spelling Service provides strict compliance with the niqqud-less spelling rules published by the Academy of the Hebrew Language, according to its developer. It recognizes acronyms and gimatria, sports a vocabulary of 394,833 words (when including kinuyim on verbs) based on 7462 nouns, 1533 adjectives, 5060 verb stems, and 1819 other words.
