Service on Big Sur to start Terminal doesn't work with Finder, works with other apps

Question

I picked up a new MacBook recently and started customizing it software-wise.

After some research, I have managed to set a shortcut for opening Terminal as follows:

1. Open Automator
2. Select New Document, Quick Action, search „Launch Application“ and drag it over
3. Select the desired application (may be located in „others“)
4. Select File->Save in the menu bar
5. Open System Preferences and select Keyboard > Shortcuts > Services
6. Provide a shortcut for the Quick Action. In my case, I have selected CommandControlT

Sadly, the shortcut CommandControlT doesn't work when the Finder is the active app. With any other app, it works.

I don't understand why, as the shortcut isn't assigned to any action in the Finder.

Thanks in advance 😃

Answer 1

There is default shortcut which may interfere: Mac keyboard shortcuts > Finder and system shortcuts:

Control-Command-T: Add the selected item to the sidebar (OS X Mavericks or later).
