Are you on Catalina or Mojave by chance?

• tasogare 7y ago
  Yes. I installed Catalina for Sidecar, only to discover the feature wasn’t supported on the 2015 MBP.

    Something about Catalina has been causing issues with both installing Xcode and massively increased phantom disk usage (not just related to TimeMachine). I didn’t experience the former (have colleagues who did though), but did experience the later and had it self correct (on a machine without TM enabled).

    Not ideal, but http://dev.zeppel.eu/luca/SidecarCorePatch http://dev.zeppel.eu/luca/SidecarCorePatch might help, apparently it works on the release version too.

      I tried already. The image quality is not worth using the feature.
