I read through the site you suggested and about the worst thing that happens from cleaning system caches (according to them) is a slow restart the first time and a reset of the list of trusted applications. My experience is that it is not generally the system caches which cause the problems anyway. It's the user caches created by all the apps like Photoshop and iPhoto which generate 100's of tiny cache files. It only takes one of these cache files to get corrupt and the app associated with it will slow down or quit unexpectedly. Font Cache files also cause some really weird problems. As is pointed out on the xlab site, cache cleaning is not maintenance. General automatic maintenance is carried out by the various scripts which are controlled by Cron and if your mac is left turned on 24/7 it all gets done at the right times. Other things like repairing permissions or running disk utility from the CD (it can be run from the startup disk with 10.4.3) are maintenance. Cache cleaning is troubleshooting and if your Mac is doing things it shouldn't be doing or running slow then you need to troubleshoot it. My personal most used favourite free thing is Applejack which is a script which you run from single user mode and it sequentially runs fsck, repair permissions, verify preference files, cache clean and, swap file removal. I run it after Disk Warrior has done it's thing and this 2 step program fixes most common problems. Another simple troubleshooting technique is to create a new user and switch to that user. If the problem goes away then the problem is definitely within your home folder somewhere. Probably a preference file, or a log-in item but it narrows it down big time. > As Shay has suggested activity monitor to see if something is using > excess machine or memory. Also a good plan.
