Jetbrains toolbox is a software that manages programs from the Jetbrains company, including the popular PyCharm interpreter.
However, it did not work for me on Mac, and I was trying to remove it. The system did not let me remove it as it claimed that Jetbrains toolbox was open and running.
The way to remove it completely is to first force quit it from Activity Monitor on Mac. Then, you can simply delete Jetbrains toolbox from the Applications folder.
