hey people, i bought my mac not long ago and i downloaded this app called iAlertU. its an app that alerts your if people are trying to steal your mac and stuff. so i made a password and put the alarm active. but then i forgot my password so i tried a few things but i didn't seem to unlock. in the end i had to hold the power button on my MBP to shut off the computer. people are telling me that is a bad way to shut off the computer so i'm wondering does it mess up my mac in anyway? for example it causes slower performance or anything? any answers would be appreciated.
