  • VMware ditches plans to support EXSi on 2019 Mac Pro

    VMware Fusion does not run on Apple Silicon today, but VMware has stated they are working on it. A blog post by their product manager says they have internal versions of it running. They also say they are planning a public beta. I’m keeping an eye on VMworld to see if they are going to release more details. 
    But set your expectations. When released on Apple Silicon, Fusion will run ARM operating systems, not x86. Same as Parallels. Which means existing VMs of x86/x86_64 won’t run. Both Parallels and Fusion are, after all,  virtualization products for a given chipset architecture and not cross-architecture instruction set emulation. Also consider that Microsoft doesn’t currently sell an ARM version of Windows to anyone other than hardware OEMs and doesn’t support it on Apple Silicon chipsets. 
    Rosetta 2 doesn’t solve the problems that would allow Fusion to run under Apple Silicon. It was designed for a simpler problem : user mode Intel applications. It does not have the full Intel architecture instruction set and architecture emulation that would allow an x86 operating system to run in emulation. The tricks used by Rosetta to get acceptable performance likely would not be applicable to emulating an x86 operating system due to the highly dynamic nature of code execution.
