Hi, I tried to install the Clean My Mac X 4.2.1 version, uploaded here on January 24, but it said that it had't compatibility with Mojave (I'd already ran this command on the Terminal: sudo spctl --master-disable). Nevertheless, I was able to install the Clean My Max X 4.1.0 version without a problem (uploaded on November 16, 2018).

Hope you guys can check it. Greetings.
