Looks Good So Far
I purchased NeoOffice and downloaded it onto a 17” 2009 Mac Book Pro running on OS X El Capitan 10.11.16. So far my usage hasn’t been complex, but in any case NeoOffice is working fine for me, and had no installation issues. For my part, I needed an App that would operate seamlessly, and let me go about my business, as has happened.
