Does the Library's computers have Microsoft Word? I am finishing up a book and my Mac doesn't offer that

If you would like, I'd be glad to help you put office (word, excel etc.) on your mac for you. There are also cloud alternatives for word processing

I don't think so. My friend needed it and there wasn't one on their laptops.

Very difficult to confirm. Only the concerned staff would be able to answer. Kindly ask them. Sorry for not knowing.
