Trying to open multiple instances of the macOS App fails.

I wanted more than one instance - i.e. more than one terminal window (I usually have at least 4). The core program can definitely do this as I can run the binary directly many times with no problem.

But launching the App...

With spotlight:

• if not running: fine
• when app running: error The application “Alacritty.app” is not open anymore.

From another terminal with open /path/to/Alacritty.app:

• if not running: fine
• when app running: error LSOpenURLsWithRole() failed with error -600 for the file /path/to/Alacritty.app.
