Below are the steps you should follow one by one to speed up El Capitan:
Step 1: Speed Up The Startup Of Your Mac
Well, first things first. When you open your Mac device, it usually opens a lot of applications all at once. Most of the time, you don’t need a lot of these applications.
And launching Mac with a lot of applications opening all at once can cause El Capitan to slow down.
To stop these applications from launching during startup, you have to visit System Preferences. Then, choose Users & Groups. Click on your username. Uncheck the unnecessary applications.
Step 2: Cleaning Up Your Hard Drive
A full hard disk drive is one of the reasons why your Mac is running slow. To find out the status of your disk drive, simply look in the top-left corner and click on the main Apple menu.
Select About This Mac and then select Storage. The status will show up. If the top bar is almost full, it’s about time to free your Mac up for more storage space.
It might be complicated, but you can do it by following these steps:
a - Simply arrange your folders and files by size.
To do this, you have to go to Finder. Then, select All My Files located in the menu bar on the left.
If you can’t see this part you can simply hold the following: Command + F + Shift.
After which, look at the top menu bar and press View. Choose Show View Options. Now, select Sort by Size and Arrange by Size.
By now, your files will be arranged by size from the biggest to the smallest.
b - Arranging your folders and files by date.
If you wish to find old files that you haven’t launched for a long time, you can arrange files and folders by date. To do this, follow the steps stated in Step a.
However, instead of arranging by size, select Arrange by Date Last Opened. After which, click on Date Last Opened in the column name. Now, you will get a list of files and folders with the oldest files first.
Note: Make sure you look at the Storage tab’s file type distribution. This will give you an overview of which data types are actually occupying the most space.
Step 3: Trimming Your System Down
To trim down your system, you need to sweep out temporary files, and cache. You also need to flush DNS.
Here’s how to clean up cache files on your OS X El Capitan:
a - Open Finder.
b - Choose Go To Folder located in the Go menu
c - Type out the following: ~/Library/Caches
d - Press Enter. Take note that you have to delete the “insides” of the folder and not the folder itself.
e - Repeat steps a to d. However, you have to replace ~/Library/Caches with /Library/Caches
f - Restart the Mac device
Flushing your DNS cache involves deleting old cache entries that actually translate domains names (e.g. websitename.com) into IP addresses.
To do this, you have to use the Terminal. In order to launch the Terminal, you have to open Spotlight and type out Terminal. You can also find it by going to the Applications folder and then go to Utilities.
Once you have opened your Terminal, you have to type in the following:
After you enter the line above, you have to input your admin password for the command to be executed.
Step 4: Free Your Mac Up For More Memory
Macs have their own memory management features. However, you sometimes have to do it yourself. First, you have to check out how much of your memory is being eaten up.
To do this, you have to go to Spotlight > Memory tab > Activity Monitor.
If there are nearly equal values for Memory Used and Physical Memory, this means your Mac devices is nearly going to need to use the Virtual Memory.
This Virtual Memory relies so much on your Mac’s hard drive and is actually very slow. It’s so slow that you wouldn’t want it to work for you and get involved in your Mac’s performance.
So, when you run out of memory, you have to manually clean it up with the Terminal.
First, open Spotlight and type out Terminal.
Once it is already open, type the following:
Then, enter your admin password to execute the command. Give your device a moment for command processing.
You can follow all the steps stated above or you can make it easy by using iMyMac’s Mac Cleaner.

Select a category. It is best to select all categories to free more disk space.
Select the data you want to clean. These data are located on the right-hand side of the screen.
Click Clean and Confirm the cleaning process.
Wait for the cleaning process to be complete. After it is done, it will show Zero KB for folders you have deleted. Some folders will not be marked as such because these are auto-recreated folders.
