Mac Book Pro 2.4 Ghz with VMWare fusion

Hello All,

I am very new to Mac. I dont know much about its "How to use".

My MacBook has 2.4 ghz Core 2 duo processor and 4 GB ram. 250 GB HDD.

As I know I cannot install Microsoft Office 2007, VS.NET 2010 and other applications those I were using on my Windows 7 PC. So I am thinking about installation of vmWare fusion on it.

If I install vmware fusion on my MacBook, will it degrade the performance of Mac computer (there I want to do some Object C programming) and virtual machine (windows 7, where I would like to use my .NEt stuff and other applications like MS Office).

What you experts recommend?

Thanks in advance.

Running Fusion on the Mac should not noticeably degraded the performance except to the extend that it uses RAM. For instance, if you allocate 1 Gig of RAM to the VMWare Fusion virtual machine, that is less RAM usable by OS X.

Another alternative is to install your Windows applications using Boot Camp. The advantage to doing this is that if you are booted in OS X, then Windows is not running at all and vice versa. The disadvantage is that you have to reboot to switch operating systems and can't use both at the same time.

You can in fact install WIndows in a BootCamp partition and still run it in VMWare fusion. That we way you have the choice of whether to operate each operating system separately or together.

Second what Strung has said. I have used Fusion for a couple of years now and go back and forth between it and Parallels. For the moment, I am using Parallels. I was having some serious performance issues with Fusion on two separate Macs configured differently. I ultimately found an issue with an expanding VM "hard disk space" that I could not identify why it was expanding. Shrinking the one seemed to really help VM performance, but on the second Mac I still see some issues.  So far Parallels is working better.  But I've had the opposite opinion in the past so we'll see.  

If I have intensive things to do on Windows, I usually use the stand-alone boot camp approach. The downside is that you don't have both Windows and OS X running together, but Windows does have full access to the hardware.  

If you are a big Office user, you might want to invest in Office for the Mac 2011.  I just installed it and it seems very nice and quick.
I use Fusion myself, but comparison tests of the latest versions of Fusion and Parallels show Parallels to be significantly faster.

Actually I want to use both at one so I was thinking about vmWare fusion. Will Max OS run on 1 GB with objective -c programming and 3 gb to vmware, will that work?
Fusion and Parallels are similar programs that allow Windows to run on OS X.  I can't speak to the object c programming as to how much memory it needs. Best way to tell is really to install and tweak memory settings until the proper mix is found. If you have info about requirements for each of your apps, this will also help you to determine a good mix.
For running Windows, Parallels is much faster than Fusion.  Also, I think Parallels has recommendations about the amount of memory to allocate to the virtual machine -- allocating more memory does not always help, and may hurt.  If you allocate 3GB to Parallels, it may run slower *and* you will definitely start paging (as MacOS + apps won't really run with 1GB) and you wiil learn how slow a computer can go.
I presume you are talking about running XCode on the Mac for your Objective-C programming - you should check the memory requirements that Apple suggests for that.  

I would suggest that you install the maximum amount of memory possible in your machine; 4GB may be enough, but I found that running XCode + Parallels + other Mac apps on a MacBook Pro Core-2 with 3GB was incredibly painful.  Now I have a 8GB i7 with 200GB SSD drive, and it never pages.


what is meaning of "Parallels"?


the net helps those who help themselves.
I find that using VirtualBox,  free VM software, works well and does not take up a lot of processing power:

I have run multiple virtual machines simultaneously with VM Fusion on a 13 inch MacBook Pro 2.26 GHz with 4 GB RAM and have not noticed any performance problems.
