Openoffice is not officially supported Mohammed.
But this is not influeneced by Office software.
Are you using SMARTFORMS in OSX? I believe this only is supported with SAPGUI for Windows.
If you enter any transaction in SE93,and click "display",under GUI Status, this will show the supported GUI versions that are supported.
If this is not the case,can you upload a screenshot to the post for clarification?
