Mac OSX – “____ is an application downloaded from the Internet.”

I see this warning every time I install or update a program on my iMac and MacBook:

[Program Name] is an application downloaded from the Internet. Are you sure you want to open it? [Web browser] downloaded this file on [Download Date].”

Replace the bracketed items with whatever the appropriate text is.  Here is a recent warning for OpenOffice.org, with a slightly different wording.

Warning Screen For OpenOffice.org

Any way, usually I will see this only the first time I run a program.  Recently, with an update of Skype, the warning showed up every time I started the application.  It was more than a little annoying, especially because it never happened before.  Today, I finally decided to find a solution.

Without boring you with the details, here was the issue.  When tried to upgrade Skype, it wouldn’t let me do it with the regular “drag and drop onto the Application folder.”  I can’t recall the exact message, but it was something to the effect of, “The existing application won’t let you do this.”  So, I logged in with my administrator account, and tried again.  No dice – I got the same message.  So, I uninstalled the existing version by dragging it from the Application folder to the trash bin, then installed the latest version.  That made it work.

Unfortunately, that was also the cause of the repeating warning.  It seems that the account that installed the application has to open it, then click past the warning.  Otherwise, all the other users of the system will repeatedly get the warning every time they try to run it.  So, I logged in with my administrator account, opened Skype, clicked past the warning, then logged out.  When I logged in with my regular account, the warning didn’t reappear.

The lesson?  When you install a program on Mac OSX, open the program first before logging out.
