Hello, I see the two options, one-time vs. annual subscription, and I read the fine print. BUT ... am I correct that the one-time license "in fact" expires every time that Appel releases the next version update of OS-X, for example 10.12 after 10.11, etc. ? Also, is this so regardless of whether the "new" version of parallels desktop just comes with the very same features than the last one ? In other words the one-time license can get more expensive than the annual subscription ? Could users who have owned (and or course upgraded) Parallels desktop for Mac for many years please advice ? Best Regards
