Question

We have an app for OS X which we distribute via our own website, it is bundled in a preference pane and comes with 3 daemons. Since 10.7.4 One of the daemon doesn’t run anymore and OS X says this:

YZ can’t be opened. You should move it to the Trash.

The console isn’t very helpful to me, yet, providing this error message:

23.06.12 18:22:15,284 com.apple.launchd.peruser.501: 
([0x0-0x176176].com.bananaglue.control.helper[1902]) 
Exited: Killed: 9

Same on OS X 10.8. We haven’t changed anything and it used to run without errors before.

Any hints how to solve that issue?

Answer 1

Check the following explanation:

The app’s authorization has been revoked. Although this app was signed by an identified developer, the certificate for this app has been revoked. There may be a problem with it. The app cannot be opened.

Quote by Krystof Vasa from Fuel Collective:

Apple is for some (to-me unknown) reason enabling the 10.8’s Gate Keeper feature already in 10.7.4. Gate Keeper is supposed to let you prevent non-AppStore or non-signed apps from launching. Gate Keeper settings are in System Preferences > Security & Privacy – make sure it’s set to Anywhere. If this doesn’t help either, here’s a guide how to disable Gate Keeper, which shouldn’t be running in 10.7.4 anyway.

Disable GateKeeper by running the following command:

sudo spctl --master-disable

Maybe you can contact Krystof Vasa and ask how they exactly fixed the problem.
