I took an iPhone 11 running the latest iOs at this time (14.4.1) and connected it up to a Mac running Mojave. I pull an app out of it as an ipa file. I copied the ipa file to the M1 Mac and double clicked it. The M1 Mac then said it was installing the app! I double clicked on the installed app and it said it would run on a jailbroken iPhone?!
My iPhone is not jailbroken and the original app runs fine on it.
