Kill 10.5’s “Are you sure you want to open it?” dead
Turn off those obnoxious “This app was downloaded from the internet” warnings OS X 10.5 throws up.
Above: Vista barely holds onto its lead as most annoying OS.
I’ve been trying for a long time to make these go away, but all I found were Folder Actions scripts to frob disk images. Now, at last, somebody has addressed the problem at its root. Thank you, Christopher Stawarz!
By the way, I've noticed the fix seems to apply only to things downloaded after you apply it, so don’t lose heart too easily when testing.

Why? Is it really that annoying
Don't take this personally, but you're defeating one of (IMHO) best features in Leopard, Code signing, Sandboxes, and App security. I hope you don't run your webserver this way.. afterall the dialog box says baby-eating-trojan...
