@hmaarrfk, we are looking into how to best provide dylib files for macOS. Apologies if you were unaware of the change - I will flag this up with a colleague...

@hmaarrfk, you can use the `ps5000aSigGenFrequencyToPhase()` function to calculate the delta phase - please refer to the [Programmer's Guide](https://www.picotech.com/download/manuals/picoscope-5000-series-a-api-programmers-guide.pdf).
