Hi mattyblue
I also use mac
You can download filezilla ftp client for free for mac, run a google search for filezilla mac
Never use mac's built in notepad (textedit) as it doesn't work well with enigma2 - it adds in a bunch of invisible data that you didn't put in
Download text wrangler from the app store, it is the equivalent of Notepad++ for windows and works a treat
Paste your C line into text wrangler , save as CCcam.cfg (exactly as that with first two C's capital and the rest lowercase - make sure the extension is .cfg and not .cfg.txt)
Now, on your box, press Menu > Information > Network - this will give you your ip address of your box
Open FileZilla and input the ip address where it says 'Host' (ip address should start with 192.168 most likely)
For username, enter 'root' , all lowercase without quotation marks
Leave the password blank, and press enter
This should go to the "/" directory of your box
Now double click into /etc folder and drag your CCcam.cfg file over to it - make sure it goes in /etc and not inside one of the folders in the /etc directory
Once that's done just make sure you have CCcam downloaded and running on your box - CCcam 2.3.0 is the latest version
(By default your boxes username is root and there is no password - I highly recommend that you set up a password though as there is a lot of hacking going around with these boxes - oPEN TERMINAL on your mac, and type telnet 192.168.x.x (whatever your ip address is) hit enter, then type root for username and enter for password, then type passwd and enter a memorable password for your box, then from your plugin menu, open the plugin called openwebif and enable authentication )
Hope this helps
