A wobbly windows implementation for MacOS inspired by Compiz for Linux.
Note: this is only a proof of concept, I am not actively maintaining the project. It may not always be stable, but I am open to contributions :)

For a demo injected into MacOS, check out this video.
Just open the Xcode project and build. You get a demo wobbly window, and can use this code to add the wobbly effect to any new app you're building.
Old instructions
- Install SIMBL loader like using [mySIMBL](https://github.com/w0lfschild/mySIMBL) or [MacForge](https://www.macenhance.com/macforge). Note that you currently need to disable System Integrity Protection (SIP) in order for this to work. - Download the [latest bundle](https://github.com/iamDecode/Jello/releases), or build it yourself (see Building). - Drag bundle onto the app to enable it. - Restart apps for Jello to take effect.Previous instructions were outdated and don’t work on recent macs (with Apple silicon) anymore. To address this, I built a highly experimental JelloInjector app (see feat/injector-app branch), that uses frida to inject into MacOS. It works on most non-apple apps I tested, but unfortunately the native Finder, Messages, Mail etc seem permanently off-limits.
To use this app you have to lower your system security which I highly advice against, but if you still want to proceed, you have to:
- Boot into MacOS recovery mode
- Shut down completely
- Hold power button while turning on
- choose “Options”
- Login with your account
- Select Utilities > Terminal from the menu bar
- Disable (part of) System Integrity Protection (SIP) with
csrutil enable --without debug - Reboot
- Enable arm64e applications by running
sudo nvram boot-args="-arm64e_preview_abi” - Reboot again
The Xcode project contains two targets, Jello will run a sample window with wobble logic enabled, JelloInject builds a bundle that can be used with a SIMBL loader.
