Use this to stop the annoying message.
Issue or symptom
When installing the SuperDrive Firmware Update 2.1 at the same time as a Mac OS X Update that requires a restart, you may receive a message (after restarting and logging in) that states:
"No Updatable Devices Found.
No devices were found that require this firmware update."
Products affected
* MacBook, MacBook Pro
* SuperDrive Firmware Update 2.1
Solution
This message is not a cause for concern--the SuperDrive Firmware Update has been installed correctly.
To avoid the message, remove the update application from your login items:
1. From the Apple menu, choose System Preferences.
2. From the View menu, choose Accounts.
3. Click the Login Items pane.
4. Select the SuperDrive Update 2.1 in the list of login items.
5. Click the "–" button to remove the update from the list.
6. Close the Accounts window.
