If you are looking to connect your Mac’s EyeTV application to a set top box such as Directv, Dish Network, Sky Boxes or virtually any other box there are several low cost options that make it easy.

If you have Directv you have 3 options

1.  SerialChannel.  SerialChannel provides a reliable and clean installation. It works through a serial or ethernet connection that connects to the usb or data port of your Directv box.

2.  SerialChannelIR. SerialChannelIR is an Universal IR blaster solution for the mac.  It uses USB-UIRT and an IR blaster cable connected to the front of your box to mimic your box’s remote to change channels.

3. eyeChange. eyeChange is designed to work with ethernet enabled Directv boxes. Most of the Directv HD boxes now have ethernet ports which can be connected to a home network. No wires necessary. Now available in the app store.

Which ever one you choose will provide a seamless channel change from EyeTV to your box.

1.  SerialChannelSky.  SerialChannelSky provides a reliable and clean installation.  It works with Dusky-control hardware to change the channels on your box.

2.  SerialChannelIR.

If you have used Xcode before you know that when you create a new project the name you give the project is used as the name for the target executable.  But what do you do if you come up with a new name for your application or want to create a similar project with some minor changes.  Well you have two choices.

1.  Rename the entire project.

2.  Rename only the executable.
Update: XCode 3.2.3 now provides a built in rename. Open the project you want to rename in Xcode then under Projects select rename.

5.  Open the Renamed Xcode project and right click (Control click) on the Target from the groups and files list. Select Info to open the properties panel.
