I have a permanent license for V6 (Mac and iOS). What I think I understand about V7 is that it will be required if I upgrade Mac OS to Catalina, and only if I want to use the Safari extension. In other words, none of the functionality of V6 will change in Catalina other than what I am able to do when I click on the icon in the Safari menu bar. Rather than using the extension, I can open the program, choose a login or identity, which will result in a page in Safari being loaded and filled in. Is this correct?
Regardless, I do recognize the need to upgrade software as OSs change. My understanding about V7 is that I can purchase a single license (not a membership) for all my devices that will suffice until V7 is somehow unusable, i.e., what I currently have with V6 (I think). However, I have been unable to find out the cost for the V7 license. I have no 1PW account because of my permanent V6 license. I have downloaded the upgrade from the web site but am leery of installing it at this point. Will it overwrite or otherwise disable V6? At what point will I be asked to pay for the upgrade?
