CubicSDR working well on MacOS

Some previous versions of CubicSDR have given me some grief on macOS. Today I found that the current release, version 0.2.5, seems to work really well.

Here you see it working with an Airspy HF+ but RTL-SDR also works very nicely.

I like CubicSDR because it has some keyboard and mouse actions that are really handy.

• Arrow up and down zooms
• Arrow left and right moves the visible spectrum
• Dragging with the mouse moves the visible spectrum
• Like others, clicking on the spectrum tunes to that frequency
• Spacebar brings up a box where you can type the frequency
• Shortcuts are shown in the window footer

Great work, I wonder when they'll get to version 1.0?

One bug I see is that if you click in the audio waveform panel it crashes.
