  1. Thank you for your reply; the loose for Apple, incompatibility!
    Damage, it deserves the full screen, already, without inflationism, but this is not a scoop at Apple…
    Bravo for your integrated router

  2. hello,
    Why does Weather4VR only run on iphone or ipad and not on mac?, application not found in the mac app store?

    1. Because developments under iOS are not compatible with MacOS. At least until today. The good news is that starting with the new M1 processor Macs and MacOS Big Sur, it is now possible to do it. You still need to equip yourself with this material.
