I recently got a MacBook with the new Apple M4 chip and need to run some Windows applications for work.

I’ve explored options like Parallels Desktop, CrossOver, and cloud-based Windows setups, but I’m unsure which one would offer the best balance between speed, compatibility, and battery efficiency.

My key requirements:

  • I don’t want macOS performance to take a hit while running Windows.

  • I’d prefer not to reboot every time (so Boot Camp is out).

  • I mainly need Windows for a few desktop apps, not gaming.

Has anyone successfully run Windows on an Apple Silicon Mac (especially M4) without major slowdowns? What setup or tool worked best for you?

    Hey Kaustubh

    I recently got an M4 MacBook too, and I had the same challenge when I needed to run few Windows apps for work without affecting macOS performance. After trying a few setups, here’s what I learnt.

    CrossOver was surprisingly good. It doesn’t run a full Windows system, so it’s super light on battery and doesn’t slow macOS down.

    Parallels Desktop (Windows 11 ARM) gives you the most compatibility. It runs really smoothly on the M4, but you’ll want to be careful with resources Windows and macOS responsive. It’s great when you need a “real” Windows environment but don’t want to reboot.

    Cloud Windows (like Windows 365 or Shadow PC for gaming) is good option if you have a reliable internet connection. It offloads everything to the cloud, so there’s zero performance hit on your Mac but of course, you’ll need to stay online.

    In my case, I ended up using CrossOver for lighter apps. It has remained stable so far, and I haven’t noticed any real slowdown in macOS.

    If you’re just running a few desktop apps and not doing anything too heavy, I’d say start with CrossOver it’s the best balance of speed, compatibility, and battery life.

    Thank you, @lena. I have used Parallels Desktop for Mac a few times before switching to Windows OS. The right choice depends on what you expect from the system and how long you plan to run Windows sessions. @Kaustubh, you don't want to keep rebooting, and it's not for gaming, so I recommend Parallels Desktop, which I used before, and be ready to spend a few dollars.
