Hi, There are a couple things going on here. The update released today is not available on 10.10.5 (min. requirement for 19.0 is 10.11) so you aren't seeing that as an option at all. Second, you have 18.1.1 currently installed, and the option to install 18.1 is a downgrade. The messaging is meant to make sure you want to downgrade from 18.1.1 to 18.1, and shouldn't have any impact on the major versions (thus no option to remove major version). Hopefully that makes sense. regards, steve
