Yeah I had to flip the developer setting toggle, but worked flawlessly for my flight (American Airlines has a watch an ad for 20 minutes of free internet that only works once per MAC)
Are you saying that on IOS 18 if you enable developer mode then each time you forgot the network it gets a new Mac? But without developer mode it does not get a new Mac each time you forget it? The Apple docs linked elsewhere in this thread suggest it only gets a new Mac once per 24 hours when you forget the network normally. I’m going on a long boat trip in the next week where this trick might work for me if so!
