+Guncel macOS surumunde once [Homebrew](https://brew.sh) kurulu olmalidir. Ardindan:

+chmod +x setup-macos.sh run.sh
+./setup-macos.sh
+./run.sh
+```
+
+Betik Homebrew ile guncel `cmake` ve `qt` paketlerini kurar, yerel mimari icin
+`location_plotter.app` paketini derler, gerekli Qt kutuphanelerini uygulama paketine
+ekler ve testleri calistirir.
+
+macOS USB UART aygitlarini genellikle iki adla gosterir:
+
+```text
+/dev/cu.usbserial-XXXXXXXX
+/dev/tty.usbserial-XXXXXXXX
+```
+
+veya bir CDC aygitinda:
+
+```text
+/dev/cu.usbmodemXXXX
+/dev/tty.usbmodemXXXX
+```
+
+Uygulama her iki bicimi de algilar. Mümkünse `cu.usb...` yolunu secin; macOS'ta
+disariya baglanti baslatan uygulamalar icin uygun olan aygit budur. UART uygulama
+acikken takildiysa port alaninin yanindaki `Yenile` dugmesine basin. Otomatik
+algilanmayan bir yol port alanina elle de yazilabilir.
+
+Istenen port baslatmadan once ortam degiskeniyle de secilebilir:
+
+```bash
+LOCATION_PLOTTER_PORT=/dev/cu.usbserial-XXXXXXXX ./run.sh
+```
+
+Port hic gorunmuyorsa `ls /dev/cu.usb* /dev/tty.usb*` ile macOS'un aygiti olusturup

+donaniminizin macOS surucusunu kontrol edin.
