This does nothing that you can’t do for yourself, plus the features that you would actually have a use for LOCK THE COMPUTER UP!!!! I have never ever had my iMac or my Macbook Pro lock up until I used this program. I am running El Captitan on both systems and have 8 GB of RAM and yet if you try to run a ‘quick’ scan or duplicate file finder it will run all night and then you have to do force a hard reboot to get back to your desktop! WORTHLESS WORTHLESS WORTHLESS etc.!!!!!! I’m one VERY UNHAPPY CAMPER Mr. App Store!!!!!!
