High Quality Content by WIKIPEDIA articles! NeoOffice is an office suite for Mac OS X. It is a fork of the free/open source OpenOffice.org that implements nearly all of the features of the corresponding OpenOffice.org version, including a word processor, spreadsheet, presentation program, and graphics program. It is ported by Planamesa Software, and uses Java technology to integrate OpenOffice.org — originally developed for Solaris and Linux — with the Aqua interface of Mac OS X.
