Apple Mac OS X is a excellent Operating System, but after months of usage, you would have installed a huge number of different software applications in it, because of which the MacBook would take a good amount of time in loading when you restart it. Now in order to make sure that the speed is restored to the highest you need to remove or cleanup your Startup Items. First of all you need to click on the Apple Icon located on the Top left of your Laptop, under which there is a option of System Preferences.

Now you need to click on the Accounts > Login Items Tab which will display a list of all the applications which would start loading associated with each Login Accounts. Hence you need to click on each of the Accounts on your Mac OS X and then ‘hide’ the Applications.
That’s it, this will complete the job of removing all the software’s which are not required to be loaded when you login to your MacBook and make sure that it loads super quick.
