Mac OS X is one very stable System, and we don't need to reinstall the system frequently as we have to do with window. However, after a while using, we still have the feeling that the computer seems running slow down than usual standard. The waiting 7 colour icon appears more often, the opening apps and it's performances become slow and laggard. Why does that happen and how to attempt to solve this problem?
There are many reasons. The hard driver get full, and that prevent the system's ordinary performances slower. Moreover, that the apps are crashed leads to impacts on the system file, the efficiency therefore becomes worse. In another aspect, the old apps that are not used any more still exist and take a significant volume of Ram memory. If you face this situation, you could try these 5 solutions:
1, Free Storage Capacity
A full HDD and even SSD always make Mac system slow down, this problem is the same as window also. Normally, Mac OS X and apps utilise Ram to storage necessary Data for their working coincided with accessing into HDD or SSD to read/write data. A full HDD make this processes limited, or worse, there are no free space for creating temporary files.
To check the free capacity of HDD on Mac OS X, you could go to > About This Mac > Storage. In a new coming up window, you easily see portfolio of data and their occupy to decide rationally deleting unnecessary things. Mac users could use some particular apps for this job to clean up the system: CleanMyMac 2, or Gemini,..
2, Rebuild system folder structure (disk directory) and clear the temporary memory.
Disk directory is a list of files saved on HDD and accompanied exact their location. Sometime, Disk directory can be deviated relative to the real position. For example, when an app is crashed or can not be saved completely file, the information in disk directory is not matched with right information on our HDD. Furthermore, there are many read/write task errors accumulated gradually make speed of data accessing slow visibly.
There are many available tools help solving above problems, but we already have a solution provided in Mac OS X: Safe Boot. The special startup will run a test to check fully your whole HDD. Safe Boot will fix all mistakes and modify unmatched aspects between real files and disk directory. It also eliminates temporary file and rubbishes, the Mac OS X system will be clear in the next restarting.
How to use Safe Boot? shutdown completely your Mac, then press power button to hold Shift button after that when you hear the common noisy sounds. When grey apple logo appears, you can free the Shift button. You now have wait for a while until the processes is completed. It takes 10 minutes or more depends on your System.
To fix disk directory at higher level, you could you DiskWarrior or Disk Utility.
3, Remove some apps running with Mac OS X
The apps that running with the system can make Mac device slow after opening up because system startup and app running are occurred together. We can eliminate them by: > System Preferences > Users & Groups.
In this window, choose " Login Items", click Clock icon to unlock modification then eliminate apps that you don't want to run in Mac OS X startup. You can also manually check some particular Folder in your HDD:
Macintosh HD > Library > LaunchAgents
Macintosh HD > Library > LaunchDaemons
Macintosh HD > Library > StartupItems
Macintosh HD > Users > Thư mục Home của bạn > Library > LaunchAgents
Macintosh HD > Users > Thư mục Home của bạn > Library > StartupItems
These are folders consist of file.plist to run app background. You absolutely can delete the old things relative to deleted apps. For example, in this picture, you see I highlight 2 files related to 2 old apps, I am gonna delete them.
Notice: For people using OS X 10.7 or over, to access Library, you run Finder then hold Option button then hit left mouse on Go menu.
4, Remove internet plugins
Internet plugins are cause of making Mac work slowly. They are installed automatically when you visit some particular website, but rarely uninstalled. It is so funny because you don't really need RealPlayer plugin since 2005s any more due to this type of video is not common at all on any webs.
To do this task, follow this map:
Macintosh HD > Library > Internet Plug-Ins
Macintosh HD > Users > Thư mục Home của bạn > Library > Internet Plug-Ins
5, Manage Ram better or Complement more Ram
Our computer use Ram always for all performances. Normally, the more capacity of Ram, the faster computer works. However, it does not always equate to that complementing more Ram is the best solution because you probably waste your money. Instead of that, try one of these solutions to manage your Ram better:
- Get rid completely of apps not using (Command +Q or go to Menu > select app name and Quite).
- Restart your Mac, the easy way you should try when your Mac is slow.
- Don't attempt to open dozen of tabs on your web browser or a mass of documents when you are not using them. Try to close the task when you finish already.
If all these solutions above don't work, then think about increase Ram capacity. It is common to see 4Gb Ram is provided with Mac devices, so we can update to 8 GB or 16 GB.
Should we reinstall the Mac OS X system when it get slow?
I suppose that reinstalling system may help, but it is not alway. Before studying these tips above, I had been alway reinstalled OS X when it work slowly by the habit of using window. After installing, it does not really solve the problems well because the HDD is still full and the habit of opening many apps in the same time. I therefore recommend before you decide to format your HDD and reinstall OS X, you should try to clean up the system, update Ram if that is necessary first then do that.
