InstallAware Helps Port Windows Apps to Linux and macOS
In this article, you’ll discover:
- How to move your Windows app to Mac and Linux
- The secret to porting with zero code rewrites
- How a new toolkit helped run 3DMark on a Mac
- What “Setup Capture” is and how it saves time
Ever built a great app for Windows? You’re proud of it, users love it, and then comes the big question: “When is it coming to Mac or Linux?” For most developers, this is a tough moment. It feels like a huge wall. You have to learn new systems, new ways of coding, and basically rewrite everything.
But what if you didn’t? What if you could take your existing Windows application and move it to GNU/Linux and macOS? That’s the promise of the new InstallAware Application Porting Toolkit. It’s a tool that helps you “port” your app with, and this is the best part, zero code rewrites.
How Does It Even Work?
It sounds a bit like magic, but the idea is actually very clever. The system uses a process called “Setup Capture”.
Think of it like this:
- You start with a clean computer (a virtual machine is perfect for this).
- InstallAware takes a “before” picture (a snapshot) of the system.
- You install your Windows app, just like any user would.
- InstallAware takes an “after” picture, sees every single file and registry change, and bundles them into a package.
This package is then used to create a native installer for Linux or macOS. It cleverly wraps everything your app needs (even parts of Wine, the Windows compatibility layer) into a single, stand-alone setup. It’s a smart way to get your app running on a new platform in no time.
Many developers know the pain of managing different installers. InstallAware has been helping with that for a while.
“InstallAware eliminated the need for us to build 40+ separate setup packages, consolidating everything into a single setup, reducing our integration costs tenfold, while providing full compliance with Windows Installer standards.”

A Real-World Test: Moving 3DMark
The team at InstallAware are self-described “hardware buffs”. They were always a little sad that the famous 3DMark benchmarking tool wasn’t available for Macs. So, they decided to make it their own test case.
They first tried the simple “Mode 1” porting method, but the 3DMark installer “choked.” They then used the more powerful “Mode 3” (the Setup Capture method) and it worked.
The results were amazing. They were suddenly running 3DMark on an M4 MacBook Air. Not only did it run, but it even beat Parallels (a popular virtual machine) in the Fire Strike benchmark. Even cooler, they were able to run advanced DirectX 12 benchmarks with ray tracing, something Parallels couldn’t even do.
What Else Can InstallAware Do?
This toolkit is part of a bigger family. The main goal is to let you build installers from a single source. You write your setup script once, and it can build a native installer for Windows, macOS (Apple Silicon and Intel), and Linux (GTK2, Qt5, etc.).
Your users get a 100% native code installer with no weird dependencies like Java. For Mac users, the tool even handles all the Apple Notarization requirements, so your app is trusted by Gatekeeper.
As a cool bonus, the team is also using their tools to fix other problems. You’ve probably seen how macOS 26 (Tahoe) puts app icons in an ugly gray “squircle.” The team announced they are “jailbreaking” those icons with a free copy of InstallAware MP, using totally legal macOS system calls.
Is This for You?
So, what’s the bottom line? If you’re a developer with a great Windows app, this toolkit is a huge shortcut. It gives you a way to test new markets on Linux and macOS without the huge risk and cost of a total rewrite. You can finally see if your app has an audience on other platforms, all by using the code you’ve already built.
