Time Tagger is supported on Windows and Linux, but not on macOS.
A workaround might be to run Windows OS on a virtual machine on macOS system and expose the USB port with the Time Tagger to the VM.
Another option to control the Time Tagger with Mac OS (and in Python) would be with TimeTaggerRPC. However, it requires a Windows or Linux machine that is connected to the Time Tagger via USB.
