# Installation {% hint style="info" %} In order to get Private API features, you must disable MacOS extra security measures, called System Integrity Protection (SIP). The reason for this is because Apple does not let us access the internal iMessage code to do things like send reactions if SIP is enabled. When disabled, we can inject a helper process into the iMessage app to call the internal functions for us. In a way, disabling SIP is similar to Jailbreaking your iPhone. {% endhint %} {% hint style="info" %} Disabling SIP can be challenging, we recommend joining our [Discord](https://discord.gg/hFgbV8Jank) to get assistance with the process if you need it! {% endhint %} {% hint style="danger" %} Disable SIP at your own risk! We are not responsible for any damages, issues, or glitches caused by disabling SIP or by using the Private API. If you use common sense when downloading and installing things, you should be just fine. Please be careful! {% endhint %} {% hint style="warning" %} Disabling SIP on an Apple Silicon Mac disables the ability to install and run *iOS Apps* on your Mac. If this feature is important to you, don't use the Private API. {% endhint %} {% hint style="warning" %} If you are using a Virtual Machine, please **take a snapshot** before continuing! You will definitely want a failsafe in case something goes wrong. {% endhint %} {% hint style="warning" %} Please ensure you have the latest BlueBubbles Server from [GitHub Releases](https://github.com/BlueBubblesApp/bluebubbles-server/releases)! {% endhint %} Now that the warnings are out of the way, lets proceed to the instructions! ## Supported Device Info The Helper Bundle currently supports macOS 10.13 and up, on both Intel and Apple Silicon Macs. {% hint style="info" %} It may support lower macOS versions, but we haven't been able to test them yet. {% endhint %} ## Instructions Please follow the instructions for your macOS version in the tabs below. {% tabs %} {% tab title="macOS 10.13-10.15 (Sierra-Catalina)" %} 1.
