After I updated to OS X 10.8.1, I keep getting this error message when I execute purge:

[ERROR] The device-file for this operating system, 'osx-12.1.0.xml', was not found. An attempt to revert to a previous revision of the OS device-file: 'osx-12.0.0.xml' has been made. Please file a Radar report with Apple, on the 'CoreProfile' component, version 'X'.

Is there anything I need to do to fix the error? To what exactly is the error message referring?

That’s probably a message a developer forgot to delete, as only Apple developers can file radar reports. – duci9y Aug 24 '12 at 8:40
That would be an answer. If then you would have a link to a page where they say just Apple developers can file radar reports, that would be perfect. – kiamlaluno Aug 30 '12 at 20:23
It’s not explicitly written anywhere that only developers can file radar reports, but when a non-developer tries to login at, they are presented with an error message saying so. – duci9y Aug 31 '12 at 8:58

The purge command is still executing correctly, but it looks like Apple forgot to update the file and it's kicking this error back.

The best temporary solution is the following:

  1. Open Terminal
  2. cd /System/Library/PrivateFrameworks/CoreProfile.framework/Versions/A/Resources/De vices/
  3. sudo ln -s osx-12.0.0.xml osx-12.1.0.xml

This will add a non destructive symbolic link that is a reference to another file; in this case you're pointing the link 12.1.0 to the previous file, 12.0.0. Since this is only a link, if an update does roll out with this file it will just overwrite the link.

This is the best temp fix, and I'm sure it's been submitted a few times to their bug tracker. Hopefully it gets fixed soon! There is an Apple support communities thread about the same thing here.

That’s probably a message a developer forgot to delete, as only registered Apple developers can file radar reports. Usually, these messages are present only in the developer betas.

Err, anybody can register as an OS X developer and create radars. At least it worked for me a few weeks ago. – patrix Aug 31 '12 at 9:25
Yep. But you have to register, that’s the point. EDIT: Wait, are you thinking that by Apple developers I mean Apple’s own in-house developers? I mean those who register as developers with Apple. – duci9y Aug 31 '12 at 9:48
Please edit your answer then – patrix Aug 31 '12 at 10:37
