Slow Mac? 15 ways to speed up a Apple computer

Mac computers boast high performance, but over time, even Apple devices can run slower. Fortunately, there are many ways to speed up an old Mac.

1. Use the application to clean

To start, try to install the application to clean your computer. For example, CleanMyMac 3 will help to remove junk files, clear cache and speed up your Mac. The developers offer a free trial version of the program.

2. Find the culprit

You can also try to solve the problem by using system Monitoring. The program displays all running processes and shows the resource consumption. Open the system Monitor and choose to sort by CPU time (CPU), and then click the program that consume the most resources and close it.

It should be noted that this solution is temporary, because the next time you run resource-intensive applications, the Mac will again begin to run slowly. Consider upgrading or replacement of iron application on a ‘lighter’ alternative.

3. Disable the animation

macOS has a huge number of effects and animations that can dramatically slow down an older Mac with integrated Intel video cards. In this case, the most reasonable solution is to disable animation and transparency. Go to Settings –> Universal access and in the tab “Monitor”, check the checkbox next to “Reduce transparency”.

4. Do not use FileVault

In OS X Yosemite and above by default, encryption is enabled FileVault, which helps to keep user data in case of theft or loss of your Mac. However, as with any encryption, computer performance is reduced. To speed up your Mac, navigate to “Protection and security” and disable FileVault.

5. Disable auto-start apps

If your computer is equipped with a large number of programs, many of them probably started automatically after switching on the Mac and work in the background without your knowledge.

To speed you need to disable resource-intensive applications by going to Settings –> Users and groups –> login items. Here you need to uncheck programs that you should not open automatically after starting the Mac.

6. Disable indexing Spotlight

From time to time, for example after installing updates, Spotlight conducts a re-indexing of the system, which takes a lot of resources. In the settings for this feature can be turned off, but it can be done in the Terminal with the command

sudo launchctl unload -w /System/Library/LaunchDaemons/

If you need to re-enable indexing, just type:

sudo launchctl load-w /System/Library/LaunchDaemons/

7. Disable indexing of photos

macOS Sierra has learned to recognize faces in your photos, but it all happens directly on Mac to ensure privacy, which also affects performance.

If you believe that such functionality is useless to you, just go in activity Monitor and quit any processes with the name “photos”. This should solve the problem.

8. Clean hard drive

Over time, the hard disk is “clogged”, so it is sometimes necessary to delete unnecessary files, especially the boot disk. Click on the Apple logo in the upper left corner, select “About this Mac” and then “Storage.” On the side toolbar appears with the functions of clearing the space.

This is true for the operating system macOS Sierra. On older versions of macOS, you can use Disk Inventory X disk cleanup.

9. Reset SMC

Reset the system management controller (SMC) helps to solve most of the problems in the operating system. To reset the SMC shut down the Mac and connect it to the charger, press and hold the power button and the key combination Shift+Control+Option. The computer will boot normally and no visible confirmation of reset will not, however, SMC will be reset.

10. Remove Adobe Flash

Flash Player has long gone, and most modern browsers do block it, so if it is still installed on your computer, it simply “eats” system resources for nothing. Try to remove it using the app AppCleaner.

11. Solve the problem with kernel_task

Sometimes Mac owners are faced with the problem of consumption of too many resources the process kernel_task. To complete it, as it is a system, so you’ll have to look for other solutions. For example, as mentioned above, you can try to reset the SMC, restart the Mac, remove recently installed drivers or even to uninstall Flash.

12. Use Safari

The Chrome browser has long been a subject of jokes due to the consumption of too many system resources. Try to use the standard Safari and Chrome leave just in case.

13. Install the SSD

If your Mac was released before 2012 and still works on the HDD, I suggest to replace it with a faster SSD. It is easy to make yourself at home, but the increase of performance and speed will be there. You can also upgrade RAM.

Remember that in newer models, which were introduced after 2012, neither SSD nor RAM can not be replaced.

14. Reset

The most radical but effective measure – formatting the hard drive and reinstall macOS. Is quite simple.

Turn off your Mac and plug it back in, hold down while loading combination Command+R. then you get into the recovery menu where you should select “Reinstall macOS”. Follow the instructions on the screen.

15. Take a look at the new Mac

If none of the above helped, there is only one option – buy a new Mac.
