Microsoft has MS Word as a word processor for Windows.
What does Apple have for macOS? I'd like same feature rich application MS Word offers.
Unless I’m missing something, Microsoft Word is also available for macOS. For more information, visit Welcome to the new Office for Mac!.
If you’re looking for Apple's main word processor then Pages has most of the commonly used features of MS Word. It's free from the Mac App Store. For more information on Pages generally, visit Create and collaborate on documents that are beautiful beyond words.
As an aside, if you’re interested in a bit of history, Microsoft Word was originally available for the Mac before it was available for Windows. More specifically, it was available for Mac in 1985, four years prior to the release of the Windows version in 1989.
If your boss or professor (or other person grading your work) uses Word, then using Word yourself can help avoid grief from possible compatibility issues that can arise when other apps export to Word format.
There is Nisus Writer Express for light to medium use, and Nisus Writer Pro, if you are a professional writer, scholar, etc. at Nisus.com. Same engine, saves to RTF by default and both are very fast.
WPS Office for Mac, it's still in beta but good to use. ANd it is free. You can download it here: http://www.wps.cn/product/wpsmac/
Apple has (for free) the programs Pages, Numbers, and Keynote. They are essentially Apple's take on Word (word processing), Excel (spreadsheets), and PowerPoint (presentations). They can be found in the App Store and Pages is very feature rich and inter operates well with Word documents, rtf files and has online collaborative and web editing as well as iCloud document syncing integrated.
Word / Office 2016 is available for macOS as well, which can be purchased from Microsoft or many other sites.
