[RSbots on MAC]Need Help[RSbots on MAC]

[Yathor]

Hello, I am posting this thread because I need some little help :



First of all, how to install Java version 6 ?

I have launched Software Update, and it didn't asked me to update my Java Application (I currently have the J2SE 5.0)

How to install Rsbots ?

I tried to launch the RSbots client from launching the download from http://www.rsbots.net/download/ with my version on Java, which is not the version 6 (currently version 5.0).
As I was watching the Tutorial posted by Rsbots on Youtube, I used the terminal and typed : chmod +x install-mac-linux.sh.
As a result, I received :

chmod: install-mac-linux.sh: No such file or directory

So what do I have to do ?
Thanks forwards for helping me out of this crap
