[QUOTE="Leon100, post: 1233519, member: 201224"] My iMac has recently started to run slow. With virtually every request I get the spinning beachball, this after nearly 2 years with no problems whatsoever. I have updated all software to try to resolve the problem, but to no effect. I also downloaded a troubleshooting list from the internet and have tried the following... - Reboot - Clean caches - Delete .plist files - Repaired disk permissions - Reset PRAM - Run file system check Now with this last one, I got the following error message... ** /dev/rdisk0s2 ** Root file system ** Checking journaled hfs plus volume ** Checking extents overflow file ** Checking catalogue file Disk0s2: I/O error Invalid node structure (4, 91) ** Volume check failed /dev/rdisk0s2 (hfs) EXITED WITH SIGNAL 8 After trying to run the file system check a few times without success I tried to restart, and my computer wouldn't restart again until the 4th attempt. Does anyone know what this message may be indicating, and whether its possible for me to resolve the issues I'm having? Any suggestion will be very welcome. (By the way I have an Intel Core 2 Duo iMac, 2.8GHz processor, 4GB memory.) Many regards, Leon [/QUOTE]
