I got my new iMac a few months ago after my very old OS 9 machine finally died. (So, Im an OS X newbie. ) The iMac is a standard 2.8 GHz, 2 GB RAM, 320 GB HD machine. Ive kept the OS up to date, so Im currently running 10.5.4. Increasingly, Ive been experiencing the spinning beachball, and increasingly, it stays spinning longer and longer, sometimes to the point of timing out. Im not doing anything involving heavy-duty apps like Photoshop (in fact, Im usually only using Entourage 11.4.0 and Safari 3.1.2 when this happens...the only other apps I run are the other Office 2004 (v. 11.5.1) apps, Acrobat 5.0.5, and Palm Desktop 4.2), and my HD is only about half full. Though OS X is incredibly stable, its gotten to the point that the spinning beachball is killing my productivityI've come to think of it as OS X's version of an OS 9 freeze. Any suggestions?
