I have TT2018 Home and Business on a Mac (or had). 12 tech calls and about 9 hours of phone time.All techs are very polite but not helpful. One told me to call Apple on how to uninstall the program. I found another way to do it but now am listed as having Free TT and cannot call anyone without paying. I have used TT products since 1987. I refuse to buy another TT product based on this year and the time that I have wasted. It kept requiring a 20 minute update and then, would go back to beginning. I finally bought a Windows based computer but will never buy TT products again.
