Mac OS X is an OS that is highly optimized in performance. That’s one of the reason why i love Mac. Even there are some weakness compared to Windows operating system, i still prefer using Mac OS X for my daily works. The combination of aesthetic and minimalist design of the operating system make the user can use Mac for hours without problems. Although it has been optimized, the Mac can sometimes be slow because of several things. The following will be given some tips for optimizing the performance of Mac OS X.
1. Clean Desktop
By leaving files and folders on the desktop, it will directly give a workload when you want to display the screen. Indirectly, this process will slows down computer performance, even only a little. Make a folder called “Archive” and keep all the files and folder to the Archive folder.
Displaying Hard Disk icon (Macintosh HD) on the desktop will not help much for your activity. You can hide it from your Desktop by opening Finder Preferences and turn off all the “Show these items on the deskop“.
2. Check your Login Items
A major factor that cause slow startup on your Mac is the number of startup item during login. Check the startup items by going to System Preferences > Accounts > Login Items and remove unwanted applications that running at startup. It’s recommended to limit under 6 items for optimal performance.
3. Delete Not Used Applications
Try to check the applications already installed on your computer. Sometimes there are some applications that works in background and increase the workload of your computer. Uninstall application that are not used for long time with App Cleaner.
4. Limit the Usage of Widget
I did not activate Dashboard, because each widgets installed would consume memory resource. But sometimes widgets can simplify workflow processes. So my advice is to limit the use or turn off Dashboard widget if it is not needed.
To turn off the dashboard, run the Terminal application (search with Spotlight) and enter this command :
defaults write com.apple.dashboard MCX-disabled-boolean YES && killall Dock
To turn on your Dashboard again, you can enter:
defaults write com.apple.dashboard MCX-disabled-boolean NO killall Dock &&
5. Use Activity Monitor
You do not need other application to monitor RAM, memory and others. Just with the Activity Monitor, you can monitor all of the above. Find out which processes are running on your computer by default and check which processes are wasting your memory resources.
6. Periodic Maintenance
Make sure to check your hard drive periodically. Delete all data you don’t use. Leave some space in your hard drive, so the index of Spotlight will be run faster. It’s also recommended to do maintenance every 1-2 months by using Mountain Lion Cache Cleaner or third party application like Onyx.
