Seti@home for OS X temporarily removed

Seti@home has "temporarily removed the Mac OS X client because it no longer works properly after the Mac OS is updated to version 10.0.1 or 10.0.2; these updates cause the SETI@home client to appear corrupted to our server. Apple and SETI@home engineers are working to correct this problem. We will post a new version as soon as we have a solution. See this page for more details. (Thanks, Kevin Hawkins.)
