After Apple recently announced a delay to OS X 10.5 Leopard I had to delay my iMac upgrade until the Autumn. This led me to thinking about how to speed up Tiger to get the most out of my ageing G5. This is what I came up with: General System 1.
A few years back you dropped significant cash to switch over from the virus-laden world of Windows to a shiny new Mac, but over time it's gotten slow and crufty. Let's clean it up. Before you get started uninstalling this and deleting that, do yourself a favor: hook up an external drive to your Mac and back everything up with Time Machine or any other free alternative . The last thing you want is for your "clean up" to turn into "holy crap where did all my Documents go." Ready? Let's get started.
According to Murphy's law , anything that can go wrong will go wrong. This holds especially true for mechanical and electronic devices. If you don't change your car's motor oil, your engine will eventually seize up.
This FAQ provides recommendations for optimizing Mac® OS X performance. Additionally, it provides advice and links to advice for troubleshooting certain Mac OS X performance problems. Comprehensive advice on this topic can be found in the "Performance" chapter of our book Troubleshooting Mac OS X .
Just like your car, your Mac needs routine maintenance in order to run smoothly. Unlike your car, your Mac can perform some of this maintenance on its own. Two important tasks to perform regularly are Disk Utility's Repair Permissions and OS X's Unix maintenance scripts. Repair Permissions ensures that system-level files have the correct privileges set; this is important because incorrect permissions can prevent applications from launching, cause problems with printing, and even affect startup. OS X's Unix maintenance scripts perform tasks that free up disk space and keep the OS tidy by updating and backing up databases, cleaning out temporary files, and cleaning up system logs. You should occasionally run Repair Permissions and the maintenance scripts when you boot your Mac into OS X.
Macs are relatively hassle-free--most people can get by without doing any routine maintenance at all. But you can greatly reduce your chances of problems, both big and small, by regularly performing a few simple tasks. I recommend performing some--such as backing up your data--diligently and often. Others require your attention only occasionally. For tips for getting your computer set-up right in the first place, see "Essential Mac Maintenance: Get set up" . Wondering how you'll remember what to do when?
For the four years I’ve been using a Mac, I haven’t used a maintenance tool. All I’ve ever done was verify disk permissions, and maybe use Drive Genius to perform some optimisation. But even that was just something ‘extra’ and not necessary according to me. The real question is, can maintenance tools really help in getting your system speedy, healthy, and less prone to crashes? The answer is a subjective yes. As a unix system, Mac OS X runs certain maintenance scripts of its own, without the user being aware of them.
