How To Use This

Create an app from this script

1. Open add_border.applescript in ScriptEditor
2. File > Export and save in a place where you can reference it
   • File Format: Application

Use with macOS Finder

1. Select image files in Finder
2. Drag-n-drop selected files onto add_border droplet

Use with Capture One

1. Go to Open With field in a Capture One Process Recipe
2. Choose Other from the Open With drop-down menu
3. Navigate to and select your add_border droplet
4. Select Process Recipe
5. Select images to process

Change Border Size

Look at comments inside the AppleScript code to see where you can change the border styles. You can create multiple apps from this same script. Simply modify the border code to your liking inside the script and export it as a new app with an appropriate name. Each app you create will add the border you coded into the script when you saved it. If you don't like what you created, just delete the exported app and create a new one.

Example ideas might be:

• add_border_10 – add a 10-pixel border
• add_border_20 – add a 20-pixel border
• add_border_black – add a black border with inner white border
• add_border_white – add a white border with inner black border

You can create different Process Recipes in Capture One that reference the different apps you created, or you can use macOS Finder to drag-n-drop selected images onto the app version that adds the border you desire.

macOS Catalina Changes

macOS Catalina introduces new levels of security to protect your system from unwanted access to your files. This change requires that you to grant explicit access to your files and folders. The add_border droplet uses the Image Event core service to modify the border of the selected image files. We therefore need to grant Full Disk access to the Image Event service so it can read and write your image files.

This information was documented in this article written by Steve Anthony.

1. Open System Preferences
2. Go to Security & Privacy
3. Click the Lock icon to unlock the panel
4. Click the Privacy tab at the top
5. Scroll down to and select Full Disk Access
6. In the right side click the "+" button
7. In the navigator popup, select the following:
   • Macintosh HD > System > Library > CoreServices > Image Events
8. Press the Open button in the bottom right corner

This should add the Image Events service to the list of apps with Full Disk Access permissions.
