Hello! I’m having trouble using ZAP for the first time. Trying on a MBP running latest macOS.

I’ve attempted getting rid of the data folder, removing Lnd folder entirely, and on different networks.

Below is the content of my logs. This has been the output for a few days:

The last couple log messages just repeat indefinitely beyond that point.

The ZAP client’s progress is stuck at 73%.
