MacOS – How to add/remove applications from “File and Folders” inside “Security and Privacy” -> Privacy Tab

I use Name Mangler 3 for file and folder renaming. There are free options out there, but Name Mangler offers a ton of features that make it well worth the $19.00 to me.

Here is Name Mangler on MacUpdate which includes links to many similar programs.

1. Once you have Name Mangler installed, launch it
2. Drag all of the folder you want to rename into the panel where it says "Drag Files and Folders Here"
3. On the right choose "Find and Replace"
4. Enter "<"
5. Under "Replace with" enter the character you want to replace "<" with or leave blank to remove it
6. Click "Rename x of x items"

Once of the many things that makes using a tool like Name Mangler valuable is that you can undo your changes, view a history of your changes, and create a "droplet" that make running the name change on other files really convenient. All of that plus being able to use Regex to build very complicated renames.

There is also a great Name Mangler Google Group where you can get your questions answered and some very advanced features and methods get discussed. They have been a big help to me.

You can get around this a few ways.

1. Easiest and Most Recommended: Select the file in Finder, right/control-click on the file and choose “Open”. You will be asked if you want to open the file, even if it is from an unknown developer.

2. Slightly More Complicated, but Sometimes Preferable: If you are not afraid of Terminal.app (found in the /Applications/Utilities folder of Finder), you can remove the “Quarantine” attribute using this command:

xattr -r -d com.apple.quarantine /path/to/folder

For example, if all of the files are in ~/Downloads/ then you would use:

xattr -r -d com.apple.quarantine ~/Downloads/

or

xattr -r -d com.apple.quarantine "$HOME/Downloads/"

Type man xattr into Terminal.app for more information about the xattr command, but the short version is that -r means “recursive” and -d means “delete the following attribute”.
