Hi There, i have a mac mini and it has slowly got slower. doing basic tasks such as opening a progam ( pages, safari) it sometimes struggles even if there is nothing else open. i have onyx and have ran all the bits in it. lost a gig in doing so! but it seems alot slower!??!?! The specs are 1.42 and 512ram and i have 30gig free hard drive space? should be quick but theres no power there??
