If you have an older Mac OS or iOS device, it may be nice to know that Apple has made their iWork productivity suite, iMovie, and GarageBand apps free to download for all users. These apps come free with new hardware, but users with old hardware had to pay $5 to $20 for each individual app. For example, a family member is still using my Mac Mini from 2009 just fine. Visit the Mac or iOS App store to download.
iWork competes with Microsoft Office. Pages is a word processor app like Microsoft Word. Numbers is a spreadsheet app like Microsoft Excel. And Keynote is a presentation app like Microsoft PowerPoint. iMovie edits video and GarageBand edits music.
