Is your Macbook Pro running slow? Here are some things to try.
Editors note: this post was originally published in July 2015 and was updated in 2017 to reflect new reviews and experiences.
Any Apple computer will start to slow down over time, but there are steps you can take to keep your MacBook Pro speedy.
Step 1: Make sure you’re running the latest macOS and have the most recent updates
- Open App Store
- Click on Updates in the upper menu
- Download and install any available updates
Step 2: Check Your Disk Space and Clean Your Mac
- Open Apple icon
- Select About this Mac
- Select Storage
- Download CleanMyMac 3 from MacPaw.
- Move large files to an external hard drive.
Step 3: Use Activity Monitor
- Open Activity Monitor
- Select View > All Processes
- Click “% CPU” to sort by the percentage of CPU capability used by each program
This information helps identify programs that may cause your MacBook Air running slow.
Programs that pull high percentages of CPU should not run on startup. To check which programs run at startup,
- Go to System Preferences
- Users & Groups
- Login Items
Remove anything you don’t absolutely need by clicking the check box next to the item and then then minus (-) sign.
Step 4: Consider hardware upgrades
Hardware upgrades, though quite expensive, can be the best way to fix a slow Mac. Software tweaks and changes can make a big difference, but you may need more. Upgrading system hardware can lead to significant performance improvements. Consider buying additional RAM for your Mac to help it improve.
Step 5: Reset the System Management Controller
Every MacBook Pro has a piece of hardware called the “System Management Controller”. Most people have never even heard of it! Running a reset of this controller can return your Mac to previous levels of performance.
The System Management Controller coordinates battery and heat, LED lights, and other parts of the hardware. Resetting the SMC allows you to re-balance all these factors.
Don’t worry, resetting this controller will not harm your Mac in any way. This won’t delete your content or user settings. It resets the hardware to its original state help your computer run.
How do you reset your MacBook Pro’s System Management Controller?
- Turn off your MacBook Pro
- Plug in your MacBook Pro’s power cord into the wall socket
- Now, hold down the Left Shift + Option + Control + Power Button, simultaneously, for 10 seconds
- When you do the above, your Mac won’t power on but will register on reset
- Release all keys after 10 seconds and turn on and run your MacBook Pro like you normally do
Please note that when doing this, your MacBook Pro should not turn on. If it turns on, you probably didn’t press one of the keys properly. Do it again until you are able to press down all mentioned keys for 10 seconds without powering up your MacBook Pro.
Step 6: PRAM Reset
Like the SMC reset, resetting the PRAM (Parameter RAM) may fix computer problems.
Resetting your PRAM will not delete the data on your hard drive. You may, though, need to restore system preferences like time, date, and mouse settings. This shouldn’t take too long.
How do I reset my PRAM?
- Shut down your MacBook Pro
- Press the power button
- Then, Command + Option + P + R in combination (all at the same time) before you see the grey startup screen
- Press and hold until your MacBook Pro restarts
- Release the keys when you hear the familiar startup chime sound that your MacBook Pro makes when it starts up
- Your PRAM reset should be complete
