Might want to try
LibreOffice. It's a fork of
OpenOffice (originally StarOffice).
Most of the OpenOffice developers went to LibreOffice after Oracle acquired OpenOffice and ran it into the ground. Consequently, LibreOffice is much more actively developed.
Another fork for Macs from StarOffice/OpenOffice is
NeoOffice. Again, NeoOffice is not as actively developed as LibreOffice.
