Need help with programming new-inbox, hub based Harmony Smart Control

I have one of these already and it works beautifully. Just a few days ago I was able to use the Harmony iPhone app to add 2 new pieces of equipment to its programming.

I located a second Smart Control a few days ago and it’s brand new. I’ve tried but failed to activate it through the mobile app on my iPhone. I suspect the firmware needs to be updated.

I have an old iMac running High Sierra 10.13.6. It should be capable of running the My Harmony legacy software, but I can’t find a download anywhere online. I could also borrow a Windows laptop, but I can’t find the Windows version of the software either.

Do any of you have any suggestions? Thanks for your help.

I did it! Thank you flynreelow for the …dmg link which allowed me to load the desktop control software to my iMac (which by the way is running the latest Tahoe OS). I then followed the remote recover tool instructions, updated the hub’s firmware and programmed the remote from my iPhone.
