I've tried to install wordpressmu+buddypress locally on may mac... I saw a step-by-step video... actually is quite easy, but in the end i couldn't change my hosts file... I downloaded mamp, installed, changed the preferences (like the video says) Installed wordpressmu and buddypress in my sites folder I did all the processes from the video, but at the end my hosts file didn't appear like the file in the video... When I type mate etc/hosts in Terminal, TextMate opens the file but the file is empty... I couldn't change to localhost.domain Does anyone can help me?
