I own a fenix3 and a 12" Apple Macbook. As the new Macbook doesn't have a standard USB port it would be very useful to connect the fenix3 to Garmin Connect via bluetooth. Is this possible?
Not to the MacBook. You can connect it via Bluetooth to an iPhone or an Android phone. From what I've read (I have an Epix, but I almost never connect it to the Garmin Connect app on my iPhone) it doesn't always work well.
My daughter has one of the new MacBooks as well, and when I got it for her I bought her the USB-C to USB-3 adapter that Apple sells. I just checked Amazon, and there are now many much cheaper choices than the Apple adapter. That will solve your problem.
