Hi, I am a first time Mac user who has only had a Mac for about a week. I am getting everything set up at present and learning my way around. I have the trial version of Parallels installed and would like to buy the full product. I understand there is a new version of the Mac OS releasing in a few weeks. Is it likely that shortly after the new OS is released that Parallels will release a new version, that would require me to pay for an upgrade if I buy the current version? If so, it seems sensible to wait a few weeks and buy the new version when it drops. However, if that's not how their release cycles work, I may as well buy now. Hope that makes sense.
