Mac Operating System is the world’s most superior operating system. OS X provided Mac users with a new modern operating system with the old foundation of UNIX. Looking for some computer maintenance tips to keep your Mac at peak performance? There are several things that you can do to increase performance and speed up Mac OS X. For basic maintenance, you don't have to download any additional apps. For deeper system optimization, you may want to download a couple tools.
Clean Out Startup Items
Some applications automatically (or when asked) set themselves as a "startup item", which causes them to open at every restart or login. You can find out what is in your startup items list by navigating to Apple Menu > System Preferences > Accounts > Login Items. You may be surprised at how many there are.
To remove them, simply select the item by clicking on its name and then hit the "minus" button at the bottom of the list. However, be sure that you know what you're removing; otherwise you may kill some critical function for the next time you restart.
Turn Off Universal Access, Internet Sharing and other things if you don't use them
While System Preferences is open, take a look at a few other things. Apple has generously included a number of very useful features as preferences. Some, however, may not be useful to you, such as Universal Access (which offers help for visually and hearing impaired users) or Bluetooth (which allows certain devices to be used wirelessly). If you don't use these features, verify that they are turned off. This will save you some valuable RAM and processor resources.
Clean Out System Preferences
Take a peek in the bottom section of your System Preferences window, labeled "Other". If there is a Preference Pane that you don't use or that you use only occasionally, disable it (either turn it "off" within the Preference Pane itself or remove it from the folder "~/Library/PreferencePanes").
Check Out Your Software
If you're running an Intel Mac, some of your software may be running under the "Rosetta" translator, which allows applications built for a PowerPC processor to run on an Intel chip. Rosetta is surprisingly efficient, but don't use it if you don't have to! There may be a patch for your favorite application that will upgrade it to a "universal build". By making sure you're running the latest version you can be confident you're not using Rosetta in vain (a utility like the App Update widget will help with this).
Clean Out unnecessary code
You're either running a PowerPC or Intel processor. You don't have to understand what this means, but you should know that, with both being options, most recent software comes programmed for both. But you don't need optimization for both - you only need optimization for your computer. Fortunately, there are utilities like XSlimmer (and Monolingual - more on this in a minute) that will strip out unnecessary code in your software. This not only helps the applications run faster; it also saves hard drive space (sometimes a lot of it).
Get rid of Languages and Translations you won't use
Apple is very considerate in providing language localizations for many, many languages. But the chances are you aren't using the Catalan, Farsi, or Klingon language localizations on your Mac. And even if you are, you can strip out the other ones you aren't using and gain more efficiency and drive space using a utility like Monolingual.
Keep an Eye on Activity Monitor
There may be other things hogging your processor's attention or sucking up RAM. How will you know about them? By using Apple's Activity Monitor, which comes with OS X. Activity Monitor will tell you about CPU usage, RAM requirements, virtual memory usage, and whether a given application is a PowerPC or Intel (Universal) build. Check it occasionally to see if there are any red flags - or keep it running for a few days (with one of the useful Dock icons or floating windows enabled) to keep an eye on when things are spiking.
Evaluate Your Widgets
There are hundreds of useful widgets available, most for free - but there are many that you won't use, even if they are very helpful to others. It takes RAM and processor power to keep these widgets running, even when Dashboard is hidden - so a judicious evaluation of what widgets you do use can boost computing efficiency nicely. Do you really need that Ski Conditions widget or the Clock widget running? If not, disable them to conserve RAM and processor use.
The new MacBooks got a bad rap at first for running very hot; the truth is, every Mac will run more efficiently with a cooler processor. Even though they've largely fixed the cooling issue in the MacBooks, I use a utility called Fan Control on mine, which allows me to change the threshold for when my MacBook's fan turns on and off. This allows me to keep my 'Book running cooler, which maximizes performance (though it does shorten battery life a little bit)
Clean off Your Hard Drive
It doesn't matter how large your hard drive is - eventually it will begin to fill up. Whether it is a huge iPhoto library, some videos you're editing, or simply accumulation of lots of "stuff", a full hard drive can cause problems. (One colleague couldn't figure out why her drive was so full - until she realized that she hadn't emptied her Trash in almost four years!)
You may not realize that Mac OS X (and the Classic Mac OS, too) uses the free space on your hard drive as "virtual memory", and it depends heavily on that virtual memory to run efficiently. If you're starting to feel sluggish, it may be because your drive is too full. There are lots of ways to clean it off - maybe a different article will cover that - but sometimes a little more free space is all you need to be a peak performance again.
Run EaseUS CleanGenius
Whenever things get slow on my Mac, one of the easy "go to" solutions is to run a utility such as EaseUS CleanGenius. EaseUS CleanGenius allows you swiftly clean up unused applications and junk files, such as System Caches, User Caches, System Logs, User Logs, User Downloads, Trash, and Safari Internet Cache, etc. It also monitors the real time disk space usage and shows you the space status by the visual graphic. What is more, this amazing software allows you easily access the contents on the device, safely eject the mounted network drive and other removable devices. It maintains and keeps the Mac at the peak performance to ease your Mac life.
It's not quite like getting a brand-new Mac - after all, the "next new thing" will always be faster than the current offerings, and no one can keep up all the time. But giving some attention to these optimization tasks won't take long, and it will pay big dividends in speed.
