Hi,
It seems that in order to run on a Mac in "Designed for iPad" mode, I need to set the "Minimum system version" to be less than the macOS system version number, otherwise it complains that it can't install it. This doesn't seem to make sense since macOS and iOS version numbers are very different. I have the minimum system version set to "15.2" but since my Mac is on macOS 12.6, I have to set the minimum system version below 12.6. That gets the app to run, but that means it's technically supporting iOS versions as low as 12.6, which is not at all the case. This seems like a bug to me or else I'm missing something.
