Show HN: Liquid Radius – Unifies macOS Tahoe's inconsistent window corners

https://liquidradius.com/
3•OlyEvans•1h ago
Every app in macOS currently has a different corner radius and as a designer this is something that has bothered me for a long time. Now with Liquid Glass's design language introducing more corner radii than ever before it's a mess that no 3rd party apps have solved before.

The dev process was challenging as this is my first solo dev project and it ended up more complex than I expected (with bricking my MacBook in the process while trying wild ways to modify macOS files). In the end I created something stable and safe but it does require SIP to be disabled and a custom boot command (instructions of how to do this are in the app and only take about 5 mins if u haven't done already).

Liquid Radius makes 95% of apps (including 3rd party apps) have consistent corners vs the less than 35% from default Tahoe.

Curious what you guys think about the tradeoff in security for a visual tweak like this. For me it's a no brainer but i realise i don't think like most people.

As an ex-Apple engineer I have a very good idea how you implemented this and why you require SIP deactivation.

With SIP disabled, malicious tools can directly patch binaries, inject shims, or drop payloads into system locations. Also, SIP works with the Signed System Volume (SSV), which cryptographically seals the system volume and enforces integrity checks.

Any app that tells a normal end‑user to “disable SIP to use me” is effectively asking them to defeat a system‑wide safety net and trust the developer absolutely.

Using this tool would be be like removing every lock in your house because you don't like the shape of the roof.

If I wanted to create malware, I'd wrap it in something like this project which ostensibly provides a service. That's far easier than trying to hack in normally.

You're right - disabling SIP is a real security relaxation, not something I want to handwave.

A few clarifications that might be useful: Liquid Radius doesn't touch /System or modify the SSV. The dylib lives in /Library, not on the SSV, and injects into SkyLight at runtime.

I definitely wouldn't recommend the average person to install this app unless they actually understand what it entails.

Genuinely curious from an ex apple engineer, are you aware of any system wide visual tweak like this that can be done without injection, or is that just technically impossible?

& thanks for your comment.
