Stephen, We have PC's at the office, and I have a mac at home. I also use an ipad, a macbook air (older) and macbook pro. I have tried both parallels and and VM Fusion. The problem I had with the macbook air is that it only had 4g memory. That wasn't sufficient. On my new macbook pro I have 12g memory, and I still run bootcamp because I dread installing all of the software and having the same problem, though I suspected it would run much better until I saw that your machines have 16g! I just couldn't get P or VMF to work at the speed I needed it to on the 4g memory machine. With P or VMF, they split the memory between the PC and Mac side when they are running. Bootcamp utilizes all of the memory for which ever operating system you are logged in to - so it works much better. I have considered purchasing autocad for mac so that I can run multiple programs at one time...but that would be expensive! Plus our IT service company doesn't handle mac's. Sorry, I have not found a fix to the issue...only had a similar experience. Apple does have a business division that not many people know about - they usually have a representative in their store. Perhaps they can help as their interest is in pushing apple products for use in corporate settings. Best of luck! ------------------------------------------- Michael Maturo AIA President Dyami Architecture, PC Chestnut Rdg NY -------------------------------------------

I have used macs for a while (1987), but not really familiar with parallels nor boot camp. I noticed that you referred to Apple for help but what did parallels' support say to try about the restriction. Though I use boot camp with Lion with an older intel mac using a separate drive for the PC applications. I only have 8MB total ram. I'll check my memory usage after starting boot camp.

Stephen, I don't know as it's been awhile since I've used a Mac Mini to run Windows-based CAD programs.
The only thing I can suggest is have you installed the latest Parallels version and service packs? Also, have you manually configured the RAM allowances for running your Parallels virtual machines? Parallels does allow some configuration of how much hardware resources are split between the Mac OS and any Parallels VMs. By default, I believe it splits the RAM between the two, so you might not be getting more than half of your RAM allocated to Parallels.
I didn't like running CAD virtually through Parallels versus natively on a Windows workstation. Sometimes the cursor just wouldn't go exactly where I wanted it to go to make a selection. There were a couple of other small things that over time made me a little nuts.

Our office just changed over to IMac's with
Lion OS
2g Graphics Cards
16g Memory
We have both VmFusion 4 or Parallels 7 installed for Windows applications (Autodesk Products)
Each machine has 16g of memory and its all used up by either the end of the day or the next morning.
The Stations start posting warnings that MAC OS has run out of memory and you must close applications or it just locks up.
Even after closing applications memory is not reclaimed.
The purge command works to reclaim memory
Have installed IClean Memory and set it to reclaim at minimal memory level to get some some of it back but it take just as long or longer to reclaim memory as just doing reboot.
Have
Disconnected the machines from our LAN (Memory Leak Persists)
Removed all VMachine Software (Leak Persists)
Restored machine to out of box state (Leak Persists)
Replaced all third party Memory with all Apple Memory (Leak Persists)
Made multiple Apple suggested tweaks (Leak Persists)
Returned one station to Apple store and they could find nothing wrong nor could they duplicate the issues. (They say it not a Lion OS issue)
Stopped all power saving (Leak Persists)
Made suggested adjustments in VM settings (Leak Persists)
Note
The one Snow Leopard Station exhibits NO memory leaks!!!!!
Any thoughts? Suggestions? (Other than boot the macs to the curb go back to PCs)
