If you’ve just bought a Mac computer and you find yourself needing a document editor, spreadsheet and presentation software that is compatible with the MS Office software then you’re in luck. You can actually download, install and use on your Mac for free (as in free beer) an alternative to the expensive MS Office software.
It’s called LibreOffice. It offers the same document editing, spreadsheet, presentation and even drawing and database features you’d normally need. Besides being free, the good thing about it is that you can save files in MS Office formats to allow MS Office users to edit and read the files you created.
