    Hello everyone!

    I am a PhD student in physics. I want to purchase a 27 inch iMac with an SSD. However I am confused about which configuration to buy. Underneath I have listed my uses and needs:

    • Running windows 10 on a virtual machine (VMware fusion). Inside the windows on the virtual machine, I will install and run Matlab and Matlab related executables.
    • Majority of the time, I would not use the virtual machine. During these times, I will use the Mac OS for document editing and web programming.

    Could someone please suggest what would be the right RAM, GPU and processor configuration for my needs.

    To be save, 16 GB RAM and SSD.. If in long term 27 inchi.

    VMWARE + maybe some apps = 6 GB vm = 2 GB windows 4 GB ->APPS
    at least
    VM in osx = 2 GB RAM

    Balance = 8 GB smooth osx apps.

    Web programming much easier since most allready install like php, perl,ruby..

    Internal allready got apache...

    for mysql just install homebrew.

    Buy it with 8 GB and install 16 Gb third party memory, cheaper than buying the additional RAM from Apple. I would not recommend running any sort of production VM on a machine with less than 16 Gb RAM. Virtual machines add very little cpu/gpu overhead, so buy whatever you think you'll need for the apps you are running.

    Do you really need to run a VM? My experience with those is just awful.

    I have a Core i7 13-inch MacBook Pro (Touch Bar) with 16 GB RAM and a 512 GB SSD. And even though it handles Windows 10 virtual machines poorly, both with Parallels and VMWare Fusion. I ended up giving up on virtual machines, and went with BootCamp.

    I wonder which configuration is needed to run a virtual machine at great speeds. Perhaps the new iMac Pro?

    You only have 2 cores on that machine meaning pretty much a core per OS, iMacs are all quad core and handle VM's far better subsequently.

    Yeah but despite a lot of misunderstanding about the performance and abilities of ARM processors in the press, a dual core Intel x86 processor can crush android and ios without breaking sweat.
