I am a PC tech in a Mac world at the moment and I'm in need of some help. On PC there where several tools I used for maintaining my computer, it kept it nice and fast and so I never had many troubles with it. I have now been forced onto a mac and so wanting to learn all the small things that makes it tick and all that jazz. Are there any cool programs for optimising and maintaining macs, one of the best ones I had for PC was one called Tuneup Utilities. Anything like that for mac? I have had a play with Disk Utility and Disk Warrior, just wondering if there is anything else.
There are some programs, but from what I've seen they're mostly geared towards solving problems. In other words, if the system is slow or unreliable in some way, there are programs to help you track down and fix these problems.
Disk Warrior is one of the important ones, actually.
For actual maintenance, there's not a whole lot to do. Here's a general 'to-do' list, but there's no one program than does these things.
1) Run 'Software Update' in the Apple-menu once a week or so.
2) Don't let your drive fill up more than 80%.
3) IF you have strange problems, launch Disk Utility and try the 'Repair Disk' and 'Repair Disk Permissions' features. This is only after you have a problem, though. I see no reason to do these things on a regular basis.
4) If you use iPhoto, once a year or so, launch it by holding COMMAND-ALT and clicking the icon. It will start-up in a mode that lets you re-build the thumbnail icons and library directory. This can help speed up iPhoto if you have thousands of photos.
The bottom line is, there's not much you need to worry about. I'm sure others here can give you a few hints, but they'll probably be small stuff, just like my list here.
use disk warrior to defrag if you have lots of large files (osx will defrag files smaller than 20mb automatically).
i'd use the disk utility to repair permissions after installing anything new (software update, new applications, etc.)... some installers may reset or change permissions from what they should be and that may cause problems later.
if you shutdown your system at night, osx won't run some of the disk maintenance scripts. that's not a problem though, you can force them to run from terminal (application>utilities). just type the following:
sudo periodic daily weekly monthly
it will ask for a password, enter on and it will run the scripts ('daily', 'weekly' and 'monthly' are separate scripts, if you wanted you could run just one of them by not entering the others, ie: 'sudo periodic weekly'). these can help keep log files small and help keep file searches quick and such.
Onyx (free) and Cocktail (shareware) are great "Swiss Army Knife" tools that allow cleanup of cache files, logs, etc. (including the aforementioned daily/weekly/monthly scripts), as well as a few tweaks to Finder and Safari (that do not modify System files). Both utilities are GUI gateways to OS functions available to users, but usually only via Terminal commands.
