I don't remember the type of connection on the Console that the data logger plugs in to. I do remember seeing something about not removing the data logger while the Console is powered (with either batteries or the 'wall wart'), so, unless I can find where that is wrong, I'm not um=nplugging my logger. However, I see one mention of a "USB-to-Serial (DB-9) Cable (#8434)" in "Optional Accessories" in the Console User Manual (no publication date - got mine back in 2015). I suspect the DB-9 port is for an RS-232 serial output. That's a very old format used in electronic equipment for decades, well before even the Apple ][. I don't think Apple ever directly supported it, however, going instead for ADB, SCSI, FireWire, ThunderBolt, and probably some I've left out! Those early Apple cables may have simply been adaptors to use RS-232 signals while creating a 'unique' product for Apple.
You can easily find BD-9 to USD cables.
However, I think you'd still need a driver in the Mac to interpret the signals. There seem to lots of RS-232 drivers around, also. But you still would not have the 'logger' portion, so you would have to settle for wx info only for when the computer is running. Plus, I think you'd also have to use the Serial version of WeatherLink from Davis (not even sure if they make a Mac version of that software). And this is all assuming that the cable and drivers did what the data logger does.
