I am currently running Cognition's 2.2 Froyo v3.04. I have my captivate rooted and all that. It's starting to get some bugs and its lagging so I want to start all over and install a new ROM. However I'm having trouble getting back to square one so I can flash the new rom. I am using a Mac and that seems to be an issue when I'm looking up how to install a new rom because everyone is using PC's so I'm sure there's many different steps. If anyone could help I would really appreciate it. Also what are the best ROM's out right now for the captivate? Is Gingerbread available for captivate yet? Thanks everyone.
