+## known issue(s)
+
+On Mac there can occure either segmentation faults or a realsense error, that the program is waiting too long for frames, when running the executable.
+Somehow it will work again if you just execute the 3d-scanner-startup-helper often enough (this is basically the realsense hello-world example).
+This will also fail a lot with a segmentation faults but after a while it will work again. At least as long as the camera is connected, when reconnecting the error usually appears again.
+I am not sure if this Error is Mac specific or wheater I am doing something wrong. However I did not manage to resolve it properly.
+If you have any Idea what the reason could be, feel free to contact me.
+
+Another inconvenience I discovered on Mac is, that the executable can only be executed using `sudo`, otherwise it will always fail with a segmentation fault.
