    It's not that I don't believe you that it's a good idea to work on a clean state (I completely agree with that), I just would like to understand your concerns about installing Parallels in this situation.

    Because you the more you add to the problem the more difficult it is to get to the root solution. I suspect your issue is you install Virtual Box (possibly and outdated version but what can you expect from freeware), then you installed Fusion and now your're trying to install Parallels. OS X isn't like MS Windows (thanks heavens) in that you have to install the OS when you begin having issues, it's much more stable. However when you begin having issues with apps, paticularly KP related issues the place to start is by following the developers instructions for uninstalling then check to see if the verison of the app is compatible with OS X verison you have installed. If it is safe then download the most up to date version. It's a pretty simple concept but most people are lazy and just don't follow the fundamentals.

    Installing I unmatched RAM is a common cause if rAM related failures. I would recommend buying matched pairs from reputable resellers such as OWC ( or Crucial.

  • ViolentA79 Calculating status...

    I wondered if any of you could help me.  I have 2 identical boxes at the front desk of our office and both keep crashing with the same exact WINDOWSERVER error.  Both are mid 2011 21.5 2.5GHZ i5 iMacs with 20GB RAM.  See my log below...

    Please create your own thread, what you are doing is called thread jacking and is considered pretty rude which I'm sure is not your intent. Once you do either myself or another will be happy to help you.

    no prob.  no harm intended.  I liked your replies and hoped you could look at my logs.  I'll create a new thread right now.
