    Yes, you can try Parallels for I think 15 days free.  Yes, you can migrate from one product's VM to another.  Go to their site and download the program if you want to try it.

    Why do you have to use Office for Windoz?  Office for Mac will read all Windoz files, and save as Windoz files.

    Thank you CSound and Swank for your answers,


    VMWare is using 4GB of RAM in my computer, that's right and that is the amount I assigned to that virtual machine. It is ok for me that the system is locking this memory for the need of the virtual machine. But I still should have 12GB for all other programs...

    Wrong, unless you have figured out a way to run VMWare with nothing else, not even OSX running.


    With VMWare running in OSX, no applications in OSX or VMWare you can expect 8 to 10G to be used, and you aren't doing anything yet.

    Reboot, start nothing except the VM, do not start anything in the VM. You should show 8 to 10G in use under these conditions.

    Is it possible with parallel to run 2 or 3 virtual machines at the same time?


    Is it possible to migrate from VMWare to Parallel

    Yes I can run more than one VM with Parallels, and this is with only 8GB RAM- Of course it starts to slow down with 3 and swapping.


    Definitely it is user friendly and seamless to migrate from VM to Parallels- fact is they offer a discount to migrate.

    I recognize this discussion has been dead for months, but I've been looking for a long time for fix to the same issue: I have 8gb RAM and no matter what I do, no matter what apps I run, within an hour all my memory is taken up.  I don't actually see a huge performance hit, but it does annoy me to see more than half my RAM taken up with inactive ram. 


    Recently, however, I've found 2 great ways to clear the inactive RAM:


    1-A free app called MemoryKeeper.  It's in the App Store.  You can run it, and it will clean up your RAM (pressumably the inactive RAM), and tell you exactly how much it cleaned up.  Plus, doubly exciting is you can choose to have it do so automatically for you, regularly throughout the day.  You can tune the automatic cleanup in the preferences. 


    2-open terminal, type "purge" and it'll take maybe 20 seconds to clean your RAM.  I read that it'll clear every last bit of inactive RAM, which can temporarilly hamper performance for programs currently running, but I don't really notice any performance difference.  And yes, I'll reiterate that all you do is open terminal and type the one-word command.  As simple as that.  I have heard that this function doesn't work on older OS X versions unless you download the "developer tools."  It runs on my machine perfectly (Mountain Lion) and I have not downloaded the "developer tools." 


    This article is a must-read: -memorykeeper/


    This is good too:


    Actually this is probably unneeded but I'd rather give too much than too little:

    inactive ram

    Inactive RAM consists almost entirely of Files you have recently Read in. It is turned into Free Memory on demand, in an Instant.


    All you are doing with Purge or that third-party software is eliminating any possible acceleration you could be getting from having those file segments already in RAM if you need to Read them again. But your Graph certainly is neater.


    If that has big appeal, I can sell you some fuel additives that make your gas mileage Go Down, or a bank account that will earn less interest because it does no compounding at all.

    I have the same problem or very similar one. I see it mostly when I use Adobe Lightroom or syncing something with Dropbox for a long time. I have 8GB of RAM and when I work on theese programs the memory is down to few MB. I know, I use MemoryKeeper but is there any way to do it automaticly? I mean I don't want to clean it all the time. When I finish and close either Lightroom or Dropbox the memory should be "released" or something but nothing happens. Still I have a few MB of RAM even if I close everything after my work.
