Is your hard drive full?

You should have at least 10-15% free space on your hard drive so that macOS can function properly. You can check the available hard drive space easily. From the Apple menu, click “About This Mac” then click “Storage”. If your Mac is full, your computer will slow down. You can easily free up hard disk space on your computer. You can delete files or apps. You can erase your junk mail. You may want to delete downloaded items. You can also move files to another disk (e.g. external disk).

Software update

Make sure that your macOS software is up to date. It is possible that you are having this issue because of a software bug and updating your version of macOS may fix it. You can check this by going to System Preferences and then Software Update. You may want to check the “automatically keep my Mac up to date” box to ensure that you are running the very latest version of the macOS software.

Too many start-up apps?

Some of your apps will automatically be loaded when you turn on your computer. Some of them might be unnecessary. Startup may be slowing you down. Go to System Preferences > Users & Groups. Click your name and then click “login items”. Use the minus icon to remove the login items. Remove any apps you don’t want starting when you log in.

Restart your computer

Simply turn off your computer. You can restart your Mac by going to the Apple menu and then click Restart. Wait a few minutes and turn it back on.

Resource hungry apps/processes running in the background

Launch Activity Monitor on your Mac so that you can see what is affecting your Mac’s performance. Go to Applications > Utilities and open Activity Monitor. And click the “CPU” tab. This will list all programs by the amount of CPU they are using. You can also view memory use by selecting the “Memory” tab. Activity Monitor will let you see if there is an app or process making a large demand.

Quit apps

Quit apps when you are not using them. You can view what apps are running. When you close an app by clicking the X icon, it will remain running in the background. This is usually okay but it may also cause your Mac to slow down. For me, some big apps, like Microsoft Word, etc, was slowing my Mac. To quit apps, right-click (or ctrl-click) and then select Quit.

Clean up your desktop, if it is messy

My desktop was full of files, folders, screenshots etc. These require memory causing your computer to slow down. Clean up to make better use of your computer’s memory. You may want to delete any shortcuts or files that you do not use or need. You may create folders and subfolders and organize your files. Clean your desktop periodically.


I wrote an article regarding the slow Cloud Keychain issue. Fixing that problem did speed up my Mac considerably. To fix that, I turn off iCloud and turn back on.

Safe Mode

Starting your computer in safe mode may help you. Safe mode may help you track down the root causes of your issues. Safe mode will disable all third party, non-default apps so that you can determine if your issue is caused by a third-party app. Safe mode will also perform some maintenance activities. Here is how:

  • Turn off your computer
  • Power on your computer, and immediately press and hold the Shift key.
  • Release the Shift key when the login screen appears. And login and wait for your computer to start up.
  • Now you are in safe mode
  • Does your problem occur in safe mode too? If not, that means that safe mode fixed it. Restart your computer normally without pressing any keys to exit safe mode. If you are unable to exit safe mode, see this article.

Reason 1: Mac hard drive is nearly full

First of all, go to check and see if you have enough free hard drive space to work with: Click the Apple menu > Select “About This Mac” > Click on the “More Info” button > Choose the “Storage” tab to check the disk storage overview and capacity.

Like every Mac user, you might have stored many huge video files, thousands of photos and music tracks on your Mac computer. The popularity of using solid-state drives (SSDs) of Mac computers means considerably less capacity than traditional hard drives. Even an iPhoto library can quickly fill up a MacBook Air’s 64GB or 128GB SSD, and nothing slows a Mac than having too much on a hard drive.


Firstly, find the large media files on your Mac, delete the unused videos, apps, photos, etc. Or you can move all of them to an external hard drive, and remove them from your Mac.

Secondly, remember empty your trash cans, say the user account’s main trash can and the iPhoto/iMovie/Mail trash can.

Thirdly, remove the junk files generated from your web browser, system, or applications. A quick and effective way is using a smart Mac cleaning software, MacClean.

Reason 2: Don’t have enough RAM

A question from a Mac user: “I have a 27” iMac (Late 2012, OS X 10.9.2) with 8GB RAM. The usage of memory is always above 7GB, even though I don’t think I am running that much stuff. This leads to the occasional hanging of a program and occasional feeling of the computer being lagged.”

Yes, most Macs ship with between 4GB and 16GB of RAM. If your Mac has only 4GB or 8GB RAM, the system might be running low when launching programs or loading documents.

You can check your RAM by using the Activity Monitor application (under Utilities in the Application folder). Click on System Memory tab and have a look at the pie chart at the bottom. If the chart is largely red or orange which means you are running out of RAM.


Step 1. Open up Terminal: ~/Applications/Utilities.
