Iphone application development with Open plug

Hi,

I'm starting to learn the iphone application development using open plug.

I am having a mini mac, the version details are:

Version :10.6
Build :10A432
Serial NUmber : YM93970H9G5

I am facing some issues in installing the Elips, It shows some prerequisites for flex builder.

Kindly provide me the steps how to install it on my machine.

Also it would be great if anyone can let me know if it is a good approach to use open plug (Elips Studio) for MAC and if there is some more adorable and good approach to start with the application development.

Regards,
Manoj Kaushik
