Hello gurus, My Mac has been sluggish for a few days, almost to a point where I have to look that it is Mac OS X and not Windows... I've investigated and it seems that the "securityd" process takes up 1.36 GB of REAL memory out of my 2 GB. I have an Intel iMac (Code Duo 1.83). It might be related: The worst seems when I start Speed Download, which I just updated it so I get ask to update the application for Keychain and it takes a long time. After that it seems sluggish. Note: I have all the latests updates. And I also installed Safari 3, but then uninstalled it. If the worst come, I can re-install Mac OS X, but I'd rather wait to October to do so... ;-) Any ideas? Help would be appreciated! Cheers!
