If you happen to purchase a Samsun monitor for your Apple, do not install the current version of MagicTune (1.0). It's happened with a couple of people already, and with me as well. If you do install it and find that your Airport card is no longer recognized or your computer does not sleep properly, that is the reason. I just wanted to give a heads up to anyone out there because it took me a while to figure out that that was the problem. The monitor will work without the software.
If you have already installed it and are facing these issues,
1. Delete the program from your applications foler.
2. Search for "magictune" on your computer and delete the .pkg file.
3. Restart and everything should work properly again.
You have been warned.
