HALLELUJAH!!! It freaking works!!!
You guys are wonderful! Thank you so much!!
Apple PowerBook with the little ANT+ dongle (plugged into the Mac PowerBook) and everything synced right up!
Yay! Hooray! Hooray! Hoorah!
I’ve spent several weeks on this, kept coming back, bought a bunch of stuff I didn’t need, and you got it working for me! Thank you for taking the time to help me. So grateful that a new cloud has been lifted from this pandemic experience!
Thank you!
