How InstallAware MP Fixes Annoying macOS Squircle Icons

In this article, you’ll discover:

• What “squircle jail” is and why it’s so annoying for developers.
• How one tool breaks your icons free so they look how you designed them.
• A peek at the actual code that uses official Apple tools to fix the problem.
• Why this tool is also great for building installers for Windows and Linux, not just macOS.
• How you can get the source code and build it free from GitHub.

Have you ever spent way too long designing the perfect, unique icon for your app? You get the shape just right, the colors pop, and it looks amazing. Then, you build your app for macOS, and… poof. It’s stuck inside a rounded square.

It’s one of the most frustrating things for a developer or designer. This problem has a nickname on forums like Reddit: “squircle jail.” It feels like your app’s personality is being trapped. But don’t worry, a clever tool has a simple fix to help you break out.

What is “Squircle Jail”?

“Squircle jail” is the name for what happens on macOS (especially noted in the new “Tahoe” version) when the system forces all app icons into a single, standard, rounded-square shape.

This is done to make everything look uniform, but it’s a real pain for developers. If your logo is a circle, a star, or any other custom shape, it gets put into this “jail” and loses what made it special. It’s bad for branding, and honestly, it just makes everything look boring.

How InstallAware Gets You Out

So, how do you escape? A tool called InstallAware MP (which stands for Multi Platform) has the solution.

When you use this tool to build your app installer, it automatically tells macOS to back off. It uses official Apple tools (documented APIs) to override the default setting that forces the squircle shape. The code literally has a function to “FixSquircleJail.”

The result? Your app’s icon is shown on the desktop exactly how you designed it. No more squircle, no more jail. It’s all handled for you during the build, so you don’t have to waste time figuring it out yourself.

It’s More Than Just Icons

Fixing icons is a great trick, but InstallAware MP is a full toolkit for developers. Its main job is to help you build one installer that works everywhere.

You can use the same project to make native installers for Windows, macOS (for both Apple Silicon and Intel chips), and Linux. The best part? The installers it builds have no dependencies. That means your users don’t have to download a bunch of other stuff just to run your app. It just works, right out of the box.

Free for Open Source

This isn’t just some locked-away secret. The team at InstallAware put the source code right up on GitHub.

If you are an open-source developer, you can check out the repository, see how it works, and build it yourself for free. It’s always great to see a company not just solve a problem, but share the solution with everyone.

So, if you’re tired of your app icons being forced into a box, InstallAware MP is worth a look. It’s a simple fix for an annoying problem, and it might just make your whole installer process a lot easier, too.
