This is really only intended for advanced users, who have hardware that is otherwise not supporting the Sidecar feature set, but who want to run the software anyway. Obviously this isn’t necessary if your Mac and iPad are new enough to simply use Sidecar through official means. If you are up for it, you can grab the Free-Sidecar utility and see the full walkthrough at Github: Using Free-Sidecar involves backing up and modifying system level files, disabling SIP, using Terminal commands, and other advanced tasks, so if you’re not comfortable with that prospect, this is not for you. But that’s where Free-Sidecar comes in, expanding the compatibility so you can use Sidecar on additional older devices. One downside to Sidecar is that the the device compatibility is somewhat limited to select newer model iPad and Macs – officially, anyway. It’s makes for convenient dual screen setups just about anywhere, whether at your desk or while traveling, and it’s fantastic. Sidecar is one of the most useful features for Mac and iPad users, allowing an iPad to serve as an external display for a Mac.
