my mac mini is a 2.3 GHz Intel Core i5 w/2 GB of RAM. lately it has been running terrible. something as simple as using the scroll wheel on my mouse immediately makes the spinning pin wheel appear, i don't thing it's a web connection issue as it does this in iPhoto too. my flash player is totally up to date also. when these types of things happen on my intel imac, i simply run disk warrier and the problem gets solved. not an option on the mini whereas it has no disc drive. my only option is disk utility which, unless i've been going about it all wrong, does nothing to fix the problems. any suggestions?
