sprintf() is deprecated on Darwin since macOS 13.0 / XCode 14.1, resulting in painful developper experience. Replace sprintf() by snprintf() in order to avoid: [702/1310] Compiling C object libcommon.fa.p/ui_console-vc.c.o ui/console-vc.c:824:21: warning: 'sprintf' is deprecated: This function is provided for compatibility reasons only. Due to security concerns inherent in the design of sprintf(3), it is highly recommended that you use snprintf(3) instead. [-Wdeprecated-declarations] sprintf(response, "\033[%d;%dR", ^ 1 warning generated.
