You can by MS Office for Mac as a standalone product, no subscription needed. If you need to install on one than more machine, it will get way too expensive to go that route, but you do have a choice.I know we all hate M$, right? Still I have to say that MS has made significant improvements in attitude and approach since Ballmer left. The only bad thing is that they are going subscription based for everything which is a non starter for me and that they are playing catch up in many if not most areas. If it weren't for the subscription issue, I might have actually given them another look.
I went subscription with Office for my home use because it would be too much money to buy standalone for my Mac, Macbook, my wife's Windows Desktop and her laptop. Using 365, I not only save a lot of money, I also can install on my iPhone and iPad. They all work together really well on my Apple Products.
