Poor practice
The only way to load a virus onto a Mac is supposed to be to trick the user into agreeing to install the malware with root or admin priviledges. So when the following window popped up during an update to Adobe Bridge after installing Adobe Photoshop Elements 4.0, I was unsure whether I should provide my password, or kill the application that the window was being displayed from. A quick Google search for OLSUpdater.app didn’t return any information at all.
So I let the window sit there for 10 minutes. The Adobe update didn’t continue, so I concluded that although there was no indication that it was so, the window was probably related to the Adobe update and input my password, after which the update finished. (Having dug into the Applications folder, I suspect it is an update for for a plug-in for Bridge, called ols – I have no idea what it does, however)
C’mon guys, Adobe is supposed to be staffed by professional developers. Don’t make us guess whether or not we should provide you with a password during the update – this screen should be clearly marked as being part of the Adobe update.
