Workaround

1. Suche die Datei: list_ports_osx.py
   • Verwende cmd + shift + [.] um den versteckten Library in deinem Konto sichtbar zu machen
   • Folge diesem Pfad: ~/Library/Arduino15/packages/esp8266/hardware/esp8266/2.7.4/tools/pyserial/serial/tools/
   • Und öffne die Datei list_ports_osx.py mit einem Texteditor
2. Comment out lines 29 and 30
3. Append these lines:
   • iokit = ctypes.cdll.LoadLibrary('/System/Library/Frameworks/IOKit.framework/IOKit')
   • cf = ctypes.cdll.LoadLibrary('/System/Library/Frameworks/CoreFoundation.framework/CoreFoundation')

The code should look like this

#iokit = ctypes.cdll.LoadLibrary(ctypes.util.find_library('IOKit'))
#cf = ctypes.cdll.LoadLibrary(ctypes.util.find_library('CoreFoundation'))
iokit = ctypes.cdll.LoadLibrary('/System/Library/Frameworks/IOKit.framework/IOKit')
cf = ctypes.cdll.LoadLibrary('/System/Library/Frameworks/CoreFoundation.framework/CoreFoundation')
