Hello everyone. I'm thinking about purchasing a new PC soon and switching from my MacBook. I'm curious if I can run macOS inside a virtual machine, since I really like that operating system. Anyway, I have a hardware question too. I plan to set up dual monitors, so I want to know: if I put the macOS VM in fullscreen on one screen while Windows runs on the other, and the VM is idle or just streaming a video, will it affect game performance? Also, when setting up the VM, I see options for memory, CPU cores, and VRAM. If the VM isn't using much, will the Windows side still consume all of its resources, or will it only use what's left—like 8GB out of 16GB RAM, with the rest going to macOS? I hope my understanding is correct. Thanks and see you all!

It's usually difficult to run both operating systems at the same time. Just keep in mind that each one uses about half of your computer, which often isn't ideal.

It runs extremely slowly, especially for video playback. Consider dual-booting or using a Mac Mini with remote access.

I share the thoughts of @DnFx91. Your computer has to handle everything twice. If the memory for your virtual machine matches the GPU memory in your APU, that reserved space will be taken. Your PC won’t realize when you click on demanding tasks, and it aims to use resources as efficiently as possible. Also, switching from Apple to PC is a good move—just stick with one platform. Consider using Windows or even Linux.

Sure, just omit the Mac reference before the post appears. The VM should consume minimal CPU if it doesn't run, and you can even halt it if needed. It will utilize the RAM you configure.

talking about the concept of running OSX on non apple hardware is fine, you just can't tell anyone how to do it.

I configured the "Trashcaned fruit" setup on an EXSi server, made some adjustments and fixes, and it performed well. People could connect to test things, even though companies aren't permitted to do this.

Confirm your intent clearly. The prompt seems designed to test engagement. Let's proceed with the core request.

I also pushed back, and I’m here to prove it.

Initially, thank you for your responses. Previously, my discussion was shut down because using macOS on a device other than a Mac violates Apple's guidelines. Despite this, I really enjoy the operating system and have no real alternative. I might purchase a Mac Mini, but it would raise my overall cost significantly and wouldn't match the performance of a PC. I changed the title to OS, but essentially, I’d be open to getting macOS if it could run alongside Windows. In short, what you’re suggesting is that running Windows and macOS simultaneously isn’t advisable. If that’s true, would running them separately instead—without simultaneous execution—ensure the virtual machine gets its full allocated RAM, VRAM, and CPU cores? Or will all available resources be shared between the two operating systems? For example, if a game needs more VRAM than is reserved for Windows (say 3GB of 6GB), would it use the entire amount or stay within the remaining limit? Appreciate any clarification you can provide. Thanks.
