It's a common problem for anyone trying to roll out SharePoint to a community that has Apple users. SharePoint is only semi functional for Safari users. If you ask "the Soft" himself he'll tell you that almost any browser from OS 9/10 is a "Level 2" browser and will have limited support for interacting with Lists and Administrative context menus.
Probably the most difficult pill to swallow though is that the stock HTML editor barely works at all from Safari. Even if the editor did work well, its still a pretty terrible user experience even for users who are running browsers that are supported. Common tasks like uploading documents, images and managing them from a text entry screen are not supported even from IE or Firefox.

Here's a Screen Shot of the stock editor.
And this is what it looks like with the RadEditor Lite:

Either way it's a step in the right direction and it's always hard to criticize free add ons too strenuoulsly.
Take if for a spin and let me know what you think.
