See below for ways to fix this.

Quick fix (for advanced users)

Use this on your terminal:

Then enter your password and you're good to go: start BootCaT like any other App.

Step-by-step guide (for regular users)

Open a Terminal in your Mac:

Once it starts you'll see a window like this (the background might be black, but it doesn't matter):

Copy the following line and paste it into the terminal window:

sudo xattr -cr /Applications/BootCaT.app

The terminal will ask you to insert your password:

Type your password, you will not see any character appearing as you type, this is normal, then press the ENTER key.

If you don't see any error messages, you're good to go: just start BootCaT like any other App.

Since BootCaT isn't notarized, the workaround presented here is needed to and run the App.
