When your computer first turns on some applications are automatically loaded – drivers and little add-ons. Some of these may be unnecessary. Here’s how to get rid of them.
– Open System Preferences. (from the Apple menu up the top left of your screen)
Click ‘Users and Groups (4th line down)
Click on ‘Login Items’
This is a list of all the applications that are set to open when you first boot OS-X. There may be some that you do not need anymore. Delete the ones you don’t need. (Don’t delete any if you are unsure of what they do. Do a google search to find out what they do first).
I had 12 and I paired it down to these 6 which I wanted to keep. Notice that these are all little e’helper’ apps that increase productivity or add features to OS X. But they actually slow things down as well, so it’s good to only have them enabled if you use them.
These little helper apps and drivers can also be in another area…
Select the ‘Go to Folder…’ from the ‘Go’ dropdown menu and type in ‘/Library/LaunchAgents‘
Delete any from there that are obviously not needed.
But wait, there’s more… you can do the same for ‘/Macintosh HD/Library/StartupItems/
I was able to delete an old Driver from a wacom tablet I haven’t used for years, some google files I never authorised, some old Testra modem software and more!
If you don’t have enough memory in your computer it will certainly slow things down. This article will help you work out if you have enough memory.
Any extra app will use system resources. I found that ‘Mac Keeper’ which claimed it would speed up my Mac was actually slowing things down at start-up so I removed it.
I don’t run any anti-virus software on my Mac at all.
Well that’s it for my list. There are some other tricks out there but these are the main ones. Doing some or all of these things should result in a noticeable speed up in boot time if things were running a bit slowly.
