  • 1.  Fusion still uses Intel processes on Apple Silicon?

    So ever since I've owned my MacBook Pro M1 Pro I've seen a steady influx of new Apple Silicon apps to the point that right now only a few apps on my system are not Apple Silicon native. Those are also not that important, like for example the KIA Nav Updater tool, which I only use once or twice a year and for which I can use my Windows 11 machine.

    Anyway, back to Fusion: afaik it has been Apple Silicon native for quite a while now but in my search for Intel processes and starting up every single app (one by one) to see if an Intel process is used, I noticed that Fusion is using the following 4 processes that are mentioned as Intel under the Kind column in Activity Monitor:

    • VMware Fusion Applications Menu Helper

    • VMware Fusion Applications Menu

    • amsrv

    • vmrest

    I'm only running arm VMs (mainly a Windows 11 instance, sometimes a Linux distro but that's far less important and I still have a x64 Windows machine on the side) so I'm in doubt whether Fusion still needs Rosetta 2 or not.

    What I want to achieve is reinstall my MacBook and not install Rosetta 2 anymore, which should be fine apart from a few apps for which I can use alternative methods/apps. But it seems as if Fusion is not 100% Apple Silicon native? Or is it just using those because Rosetta 2 is installed on my system?

    So in short: will Fusion be able to fully run on an Apple Silicon machine without Rosetta 2 installed?

    The first three of those processes are for the VMware Application menu that’s in the Mac’s menu bar. I wouldn’t worry about it because you should turn it off and stop using it. VMware states it is deprecated and will be dropped in a probably not too future release. 

    vmrest is associated with the REST API services. Not a big deal since it isn’t used much, if at all  

    It would not surprise me if some of the bundled CLI commands are still Intel. I would not be worried about Fusion not being 100% native.  The parts that really matter are ARM native code. And Rosetta really isn’t a drain on the system.for the vast majority of use cases. It does a one-time translation of apps from Intel to ARM. The resulting translated code runs natively.

    I appreciate the reply and explanation. I fully understand what you're saying.

    However, having said that, my goal is to not enable Rosetta 2 altogether. Sure, it's been running just fine so I do trust what you say about it not really being a drain on the system, so it's more about my personal goal of not having it enabled at all.

    Is that at all possible? Or does Fusion require Rosetta nonetheless?

    Rosetta doesn't really add much overhead, and there's no risk of having it enabled.  Until Fusion updates their code, there's nothing you can do.

    I've done a quick scan of the executables within the Fusion 13.5.1 bundle. With the exception of VMware Fusion Application Menu.app, everything else seems to be compiled as universal x86_64 and ARM binaries. 

    My guess is that Fusion will run fine without Rosetta.

    Rosetta is not something that I'd go out of my way to avoid installing. But as  notes, Rosetta doesn't make much of an impact to a system, and its benefits outweigh any impact that it has. If you have something compiled as a  universal binary, macOS will prefer the native architecture (that can be over-ridden on Apple Silicon in the application's Get Info dialog if you need to).
