I believe libreoffice also works on Mac, so you should just be able to install it and your documents will work fine.Thanks. Now only need transfer all to the mac mini after i got it set up. Only need to figure out how to use my libreoffice calc documents in IOS. The rest is not a problem.
Mac also has an office suite with numbers, pages and Keynote which are very good and versatile programs also, but if you are used to libreoffice then just download the Mac OS version and you will be good to go.
