MacBook Pro Slow? Causes & Fixes


macbook pro slow"My MacBook Pro is running very slow now. And it is just less than one year old. At first, I thought I might have been caught a virus or something. But after running a Mac antivirus, it found nothing. Also I rarely download or install those unfamiliar applications, nor do I surf the net for those not clean websites. So what should I do with my slow MacBook Pro?"


There are quite a number of reasons that may cause a MacBook Pro running slow or slower than usual. Basically caused by two reasons: outdated hardware & poor Mac system maintenance.

  • Running too many apps at one time. Any computer can get slow if too many programs want to join the fun on your MacBook Pro at the same time.
  • Shortage of free space in Macintosh HD. Usually you need at least 10% of extra space for your applications to run efficiently. If your hard disk is nearly full, your MacBook Pro can be pulled down at great level.
  • Lots of Login Items. This can also make a MacBook Pro work not that smoothly, go to "System Preferences" then "Accounts" and click the Login Items tab to see details.
  • Cluttered Hard Disk. There are many useless and duplicate data or applications in our hard drive which will kill a lot of free space of your disk.
  • And more reasons causing MacBook Pro machine slow.

More about MacBook Pro – It is a line of Macintosh portable computers introduced to market by Apple in 2006. Generally there are 2 designs for the type of MacBook, one is largely carried over from PowerBook G4 while the other is known as the unibody model. But both designs use aluminum. To some large extend, the unibody-designed MacBook Pro follows the styling of the original aluminum iMac and the MacBook Air, and it is slightly thinner than its predecessor, albeit wider and deeper due to the widescreen display.
