In extreme cases (if you use different applications that change the network settings) - reset the application settings (I use CleanMyMac for this). Solution: reset the DHCP settings (in the mac os network settings). The problems I noticed: mirroring does not start. You can control both from the application itself and from the TV remote control. Very, very convenient to mirror the image on the TV! In this case, the player has controls: scrolling. Everything is very simple and understandable! It can play both the desktop and any selected application (you need to add any program to the playlist). In my opinion, the application is very convenient and simple. I decided to leave a review: since I see undeservedly low ratings for this application.
