HI Folks, new here, i have had this iMac OS X ver: 10.5.4 for a year, i use FoxFire as a browser, i have many Bookmarks, now my iMac has slowed to a crawl and i get the spinning rainbow for several minutes before it gives me the URL i select from the Bookmark menu. what do i need to do to get my iMac to respond the way it did when new ?? and get rid of the spinning rainbow ? do i have too many Bookmarks or do i need more memory ? thank you all in advance for your help and concern.
