Status:Open Resolved:
Product:macOS + SDK Product Version:macOS 10.12, 16A323
Classification:No Value Reproducible:Always
 
Area:
Something not on this list

Summary:
When using the 'Open With/Other' prompt in Finder and setting a new default application, Gatekeeper says the file can't be opened because it is from an unidentified developer.

Steps to Reproduce:
1. Open Finder.
2. Click on a file.
3. Open the File menu for that file.
4. Click 'Open With,' then 'Other.'
5. Choose an application, then mark the 'Always Open With' checkmark


Expected Results:
The file will open with the specified application.

Actual Results:
A Gatekeeper dialog appears stating that the file is from an unknown developer thus it could not be opened. A screenshot of the dialog box is attached.

Version:
macOS 10.12, 16A323

Notes:
The dialog box attached says that QuickTime player created that file. That is false. Another app created that file. 

Configuration:
This does not occur if you simply choose an application pre-listed in the 'Open With' submenu. This also does not occur if you do not mark the checkbox entitled 'Always Open With.'
