MacBook Air with M5: what it means for running Windows apps on your Mac
Apple just announced the new MacBook Air with M5, and it’s the most capable fanless laptop Apple has ever made. Faster chip, doubled base storage, Wi-Fi 7, and up to 32 GB of unified memory — all starting at $1,099.
If you’re eyeing one (or already ordered), you might be wondering: what about my Windows apps? Whether you use Windows-only software for work, school, or personal projects, the M5 MacBook Air is a strong choice. And with Parallels Desktop, you don’t have to give any of it up.
Here’s what’s new, and why it matters for running Windows on your Mac.

What’s new in the MacBook Air M5
Apple’s M5 chip is a meaningful step up from M4. Here are the numbers that actually affect your day-to-day:
- 10-core CPU with up to 15% faster multithreaded performance than M4
- Up to 10-core GPU with 30% faster graphics performance
- 153 GB/s memory bandwidth — 28% more than M4 — so apps stay snappy even when you’re juggling multiple windows
- Neural engine built for AI tasks, with 4x faster AI performance than M4
- Base storage doubles to 512 GB, configurable up to 4 TB with 2x faster SSD read/write speeds
- Up to 32 GB unified memory, up from a max of 24 GB on the M4 Air
- Wi-Fi 7 and Bluetooth 6 via Apple’s new N1 wireless chip
- Up to 18 hours of battery life
Available in 13-inch and 15-inch sizes, starting at $1,099. Pre-orders open today; availability starts March 11, 2026.
Why the M5 is especially good news for Windows users on Mac
Running Windows in a virtual machine (VM) is a memory- and CPU-intensive task. The better your Mac’s specs, the better your Windows experience. The M5 raises the bar in a few ways that matter:
More memory to work with. The M5 MacBook Air now goes up to 32 GB of unified memory. With Parallels Desktop, you can allocate a comfortable portion to your Windows VM — say 8–12 GB — and still have plenty left for macOS apps, browser tabs, and everything else running alongside it.
Faster, more responsive VMs. The M5’s 15% CPU gain and 28% memory bandwidth improvement translate directly into how quickly Windows boots, how fast apps like Excel or AutoCAD open, and how smooth multitasking feels. On modern M-series Macs, performance is not an issue — the experience is genuinely quick.
Double the base storage. Starting with 512 GB means you have room for a Windows VM (typically 30–80 GB depending on apps), your macOS files, and your documents without needing to immediately upgrade. If you work with large Windows applications, consider the 1 TB or 2 TB configurations.
AI is built in. The M5’s enhanced Neural Engine powers Apple Intelligence features in macOS Tahoe. While Windows VMs don’t directly tap the Neural Engine, the chip’s overall efficiency means more headroom for demanding workloads on both sides of the fence.
Does Parallels Desktop work on M5 Macs?
Parallels Desktop 26 supports Apple M5 chips, including the new MacBook Air. You can run Windows 11 on Arm, install the Windows apps you need, and get to work in minutes.
A few things worth knowing:
- Windows 11 on Arm runs natively. Parallels Desktop is authorized by Microsoft to run Windows 11 on Arm on Apple Silicon Macs. There’s no workaround needed.
- x86 Windows apps work too. Windows 11 on Arm includes Microsoft’s Prism translation layer, which handles x86 and x64 apps automatically. Microsoft recently added AVX/AVX2 support through Prism, which expands compatibility with demanding applications. Most Windows software just works.
- Over 200,000 Windows apps run on Parallels. From QuickBooks and AutoCAD to niche industry tools, Parallels users run the full range of Windows software on their Macs.
- Coherence mode keeps things tidy. Rather than staring at a Windows desktop, you can run Windows apps directly on your Mac desktop — no full Windows UI in the way. Excel opens like any other app, sits in your Dock, and shares your clipboard with everything else.
Who benefits most from the M5 MacBook Air + Parallels Desktop
Switchers from Windows. You bought a Mac but still need one or two Windows-only apps. No need to keep a second PC. Parallels Desktop runs them on your MacBook Air as if they were native Mac apps.
Students. Your university’s lab software, courseware, or engineering tools may require Windows. The M5 Air’s combination of power, portability, and 18-hour battery life makes it easy to run macOS and Windows on the same lightweight laptop all day. (Parallels Desktop is also available at a discounted education price — see the education plans here)
Creative and business professionals. Design software, ERP systems, finance tools, and productivity suites often have Windows-only versions or Windows-only add-ins (Excel macros are a common one). Worried your Excel macros will work? They do. The M5’s extra CPU and memory headroom means you can run demanding Windows apps alongside your macOS tools without slowdowns.
Developers and testers. The M5 MacBook Air can comfortably run multiple VMs alongside your editor, terminal, and browser. Test across environments without a second machine.
DevOps engineers. The M5 Air is a capable daily driver for DevOps workflows that span both operating systems. Running Linux or Windows Server VMs on your MacBook Air lets you replicate staging and production environments locally, test infrastructure scripts, and validate CI/CD pipelines without spinning up cloud instances for every iteration. The M5’s CPU headroom and 32 GB memory ceiling mean you can keep multiple VMs active at once — a Windows build agent, a Linux container host, and a macOS development environment — all on the same machine. Parallels Desktop is built for exactly this kind of multi-VM, cross-platform workflow. Learn more about Parallels for DevOps.
Getting started: run Windows on your M5 MacBook Air
Setting up Windows on your new MacBook Air with Parallels Desktop takes about as long as it takes to download Windows — usually under 15 minutes from launch to your first Windows app.
- Download and install Parallels Desktop on your M5 MacBook Air.
- Open Parallels Desktop and choose “Install Windows.” It walks you through downloading a licensed copy of Windows 11 on Arm automatically.
- Set how much RAM and CPU cores to allocate to your Windows VM. For most users, 8 GB RAM and 4 CPU cores is a solid starting point on a 16 GB M5 Air.
- Finish setup and launch your first Windows app. Your Mac and Windows desktops share files, clipboard, and printers automatically.
That’s it. No manual partitioning, no Boot Camp (which Apple removed with the M-series transition), and no command-line steps.
Frequently asked questions
Can I run 32-bit Windows apps on the M5 MacBook Air?
Windows 11 on Arm dropped support for 32-bit apps. If you rely on a 32-bit Windows application, check with the developer for a 64-bit version. Most commercial software has been updated in recent years.
How much memory should I allocate to my Windows VM?
A general rule: allocate roughly half your total RAM to the VM, leaving enough for macOS. On a 16 GB M5 Air, 8 GB for Windows is comfortable for most productivity workloads. If you upgrade to 24 GB or 32 GB, you have more flexibility for memory-hungry applications.
Does running Windows drain the battery?
Running a VM uses more power than running macOS alone. Real-world battery life with an active Windows VM will be lower than Apple’s quoted 18 hours, but the M5’s efficiency improvements help. For long sessions away from power, you can pause or suspend the VM when not in use.
Which edition of Parallels Desktop should I get?
For most Mac users who need Windows apps, Parallels Desktop Standard is the right starting point. Parallels Desktop Pro adds more vCPU and memory options per VM and is a good fit if you’re running demanding applications or developer tools on a 24 GB or 32 GB configuration. Business and Enterprise editions are for teams and IT-managed deployments.
Will the M5 MacBook Air get too hot running Windows?
The MacBook Air is fanless, which means it throttles under sustained heavy load rather than spinning up a fan. For typical productivity workloads — Office apps, browser, ERP software — you won’t notice any throttling. The M5’s efficiency improvements over M4 also reduce heat generation, giving the Air more thermal headroom than before.
The bottom line
The M5 MacBook Air is a well-rounded upgrade: more memory, faster chip, doubled storage, and the new wireless standard — all in the same light, quiet, all-day design. For anyone who needs Windows apps on a Mac, this is one of the best machines you can buy.
Parallels Desktop makes the transition straightforward. Install in minutes, run your Windows apps alongside your Mac apps, and stop thinking about which operating system you’re in.
