Spinning beach ball
The ball keeps appearing, upto a few times daily with rarely time to close applications and allow more resources to whichever may need them before the system apparently locks up.
This started several weeks ago and I'm not using more memory intensive or processor intensive applications than I usually do and I appear to have sufficient memory and disk space.
The problem occurs systemwide and even hours of inactivity is an insufficient cure. Eventually "pulling the plug" is the only solution.
I always use the Disk Utiltity after such shutdowns and frequently use the "MacJanitor" application.
There are many threads posted re this problem, but circumstances certainly dictate different solutions.
Thanks in advance for suggestions.
