DMA allows EU regulators to designate certain platforms as gatekeepers. Platforms that are designated gatekeepers are subject to different requirements under EU law than those that are not designated gatekeepers. The EU designated iOS as a gatekeeper[1], but did not do the same for MacOS. So while you are correct that there is no technical barrier, you are incorrect that they are the same under EU regulation. Involving EU regulators in product design for designated gatekeepers was the entire point of the law, so this is the desired effect. Regulators want the flexibility to e.g. work with the gatekeeper to design feature modifications, like the default browser selection screen[2], for other aspects of designated gatekeeper platforms. One can choose to see this as good or bad, but this is clearly the intent of the law. 1 - https://ec.europa.eu/commission/presscorner/detail/en/ip_23_4328 https://ec.europa.eu/commission/presscorner/detail/en/ip_23_... 2 - https://developer.apple.com/support/browser-choice-screen/#:~:text=To%20meet%20the%20requirements%20in,opens%20Safari%20on%20their%20iPhone https://developer.apple.com/support/browser-choice-screen/#:....
