i been noticing my mac acting funny, at 1st i dismissed it as no big deal but now it has become more frequent. instead of happening occasionally its happening constantly. my mac has been in the exact same location since i owned it and my mouse surface hasnt changed. theres no debris i can see in the mouses eye. its like the computer is freezing then releasing the pointer. i cant even guess about why the dock icon graphic tops are breaking up. i ran my permissions and all is fine there. anyone else know what it could be? thanks for any help.
sweet the dock icons are full again. so far so good about the mouse. i forgot a couple months back i deleted my system folder(duh) and never reinstalled the techtool. i guess i paniced thinking something malicious was attacking my comp. sorry for assuming the worst. thanks for setting me straight.
