| About three weeks ago I went through a major day-and-a-half battle to get a Mac Pro 5,1 on OS 10.9.2 to behave. I was getting bizarre Finder crashes, infinite beachballs when trying to import any element at all into AE, even Disk Utility freezing up. I did a major update to my backups, did a clean install of Mavericks and reinstalled all apps and plugins one by one. That took most of a day. However the machine was still intermittently unusable, even to the point of refusing to Shut Down properly. Next thought was "bad RAM." I started removing and swapping RAM sticks until I narrowed it down to the one that seemed to be the culprit. Bam. Looking good again. Until today when the problem recurred. Long story short, through Console I traced the problem to a disk i/o error on an external Firewire drive. Console is pretty great. I took the drive off-line and everything was back to normal. Huh. Machines. I learned that many symptoms can be caused by many things, not always the most "logical" or the first thing that comes to mind. Robert W. Walker Los Angeles CA USA |
