In the news (/., MacRumors): yet another attempt at malware for your mac. This one’s being touted as a virus but seems to be just a trojan.
Nevertheless, I briefly considered some advice in the MacRumors comments to stop running as an admin user. (See also the explanation of admin user powers in this informative thread.) But I consider myself geeky enough not to double-click something dangerous, so I’ll wait until a real virus starts circulating before I do anything that inconvenient in the name of security.
On the positive side, today I stumbled across HyperJeff’s catalog of OS X Apps while surfing. It’s a huge, unwieldy list, but handy if you want to look up all the mac sudoku apps.
