To those who are wondering whether they can connect their Epic to a Mac for USB and bluetooth file transfers: You can absolutely mount your Epic on a Mac. From the Epic's home screen, either go to: (1) Home Screen (Menu Button) > Applications > Development or (2) (under Launcher Pro only) Home Screen (Menu Button) > Preferences > Advanced Settings. From there, enable USB Debugging. Now plug in your micro-to-USB cable. A prompt will appear on your Epic; select Mass Storage. Your SD card will then appear on the desktop of your Mac and you can transfer whatever you like. Here's the other way to mount your SD on a Mac: Switch off your Epic, remove the SD card, slip it into the card adapter it came with and plug the adapter into your USB port. (I do hope that everyone who experiences connection issues with a Mac and any other smartphone or media player will now know enough to try this before posting rants about how bad their new ____ is for "causing" the problem.) Bluetooth also works, though you won't be able to see the Epic's file menu on your Mac's desktop. Under bluetooth, your Mac will identify and pair with your Epic (and identify it as a "smartphone") as soon as you make your phone and Mac visible and set up your Epic on the Mac as a device. However, your Mac won't connect until you access the pull-down bluetooth menu from the upper right-hand corner of its screen. From there, scroll down to the name of your device and select "send file". Select the file you wish to send and you're done. You should also tell your Epic always to allow your mac to send files if you don't want to kill bluetooth transfers under apps or disrupt whatever else you're doing on your phone to answer individual prompts.
