Apple periodically releases newer operating system versions, as well as minor updates for the current OS. However, sometimes a Mac owner may obtain a negative result instead of the expected performance boost. For instance, after upgrading to macOS Sierra or High Sierra, it might take a plenty of time to launch certain or all applications. A reboot does not always help. So, what is the matter?
Mostly, the reason for a slowdown is a lack of disk space. Of course, there might be some other causes of system failure in case a user did not follow instructions properly or missed something. However, in most situations, it is enough to wipe the hard drive and take care of the stored information. It is necessary once the restart does not work.
Please keep in mind that you should not panic immediately after the update. The system has to get acquainted with all the changes before starting to work with the expected speed. After the upgrade, your Apple computer has to re-index the drive for further usage with Spotlight and Siri. Those are two search tools set by default on any Mac. It may take some time, especially if the person has a big hard drive with too many information. Do not interrupt the procedure as it may lead to greater problems.
In other situations, it is better to test the speed of your Mac, detect the core problem, and act. Under the “act,” experts usually mean cleaning up the system. That is what this article discusses.
Mac Running Slow after Sierra Update: In-Depth Issue Analysis
“Why does Sierra update slow down my Mac?” That is a common question, so Apple first recommends analyzing the potential causes. It will help to understand why the computer is running slower than before as well as measures to consider while trying to boost macOS Sierra performance.
Please keep in mind that your Mac won’t be flying from the first attempt, as there are many new things to set up properly. For instance, a new Photos software must index and check all images for detectable faces and some other stuff. Otherwise, the app will not work the right way.
Here are the factors a Mac owner should pay attention to first of all:
- Mac’s startup disk may lack some space. It might be full of duplicate files, system files, caches, and other things a user does not actually need.
- A specific application may need more space than it is available on the target machine. It is possible to check how much memory is accessible. Move this direction: Apple menu à About This Mac. You will see what you are interested in in the Overview menu. Every downloaded application should have a special help section. Turn to it to discover more about the system requirements.
- In order to discover the ways to reclaim memory, it is important to go to the Apple menu and About This Mac again. Then, choose Memory tab, press Memory Upgrade Instructions in the lower part of the window. Mind that not all Macs have this feature.
- Make sure you have stopped all running applications that are not compatible with your Mac’s model. There are times when a software may need another processor or graphics/video card. Once again, the developers specify things like that in the attached documentation. If you want to check the installed processor, pick Overview in About This Mac. As for the cards, select Displays in the same menu. You will see the information on the graphics card in the middle of the window.
- Stop any applications.
- Disk Utility is another helpful, native Mac’s tool that can assist in managing various problems.
- Activity Monitor is a tool that can detect which items are ‘eating’ most of Mac’s.
Do I Need to Perform macOS Sierra Speed Test?
One day, the idea to perform an overall macOS (or the older OS X) speed and performance test might come across your mind. But believe us, it’s easier said than done. You will need a whole set of highly specialized applications and an in-depth knowledge of how to use them to complete this task. We strongly advise you not to mess with this exercise and leave it to experts.
What can you do on your part? Two things:
- Take the stop-watch and mark the time of your Mac booting and launching the most widely used applications. Then compare the numbers you got with suchlike values obtained by other users – look for them on Apple Support or Discussions Communities forums.
- Read this thread and examine Activity Monitor from top to bottom – it can give you tons of valuable performance-relevant info if you know where to look.
Once you detected the core problem, try this solution offered by the Apple’s team and other experts.
- Back up your computer with the help of Time Machine or other specialized tools. You can also use Terminal in case you are an advanced user.
- Shut down the system to reboot in “Safe Mode.” This feature helps if the machine does not quit starting up. Watch how your Mac functions in this mode as compared to the regular regime.
- After that, reboot in an ordinary way.
- The last thing a Mac owner can try is to temporarily create another User Account. Sign in to find out whether the issue is relevant only for the previous User Account. After the process of troubleshooting is over, delete the extra user Account. Otherwise, it will just take some space.
Troubleshoot Your Problems with 5 Ways to Speed up macOS Sierra
At last, you have reached the part of the article telling how to speed up macOS Sierra with the help of some cleaning procedures.
Messaging Is Fun, But Watch Out!
People prefer messaging to calls and other types of communication, so it makes sense most of them use Messages application a lot. Pay attention to how many animated GIFs and stickers you exchange with your friends via Mac’s Messages. This chaos may require a plenty of space. Overall, the animated GIFs often cause system slowdown, especially when the messages window is constantly opened. Clearing a chat log may help to prevent those animated images from playing all the time in the background.
If you are not sure whether your Messages app is the exact reason for the sluggish system, launch Activity Monitor to check its spike in CPU work log.
Decrease Transparency & Motion to Make It Work
Eye-candy effects are great and attract millions of Apple users, but they require some memory as well. Thanks to its numerous upgrades, macOS Sierra offers a simple solution. Once you switch off the effects, you may notice a performance boost. Those who launch many applications at a time should mind this advice:
- Launch the Apple menu and move to System Preferences. Select “Accessibility.”
- Choose “Display.”
- Scan the box to find “Reduce motion” and “Reduce transparency” respectively.
- Quit the System Preferences menu.
Be ready that the UI elements will change in their look. Even though you may lose part of the visual pleasure, it guarantees a speed boost.
Wipe Mac’s Desktop
Many users underestimate the importance of keeping the desktop clean and organized. The chaotic desktop arrangement is not convenient. Moreover, when it is overloaded with items, it may lead to the noticeable drop in Mac’s speed. What a user can do is place all the desktop elements into a new folder on the desktop. Launch the folder each time you need some of those files. It is possible to hide the desktop icons with the help of a defaults command. The experienced Mac owners can do that using Terminal and special codes.
What Are Some of the Background Tasks?
Background tasks are those Mac owners do not see and often do not even suspect. If you wish to find out which processes are on, take the steps described below.
- Go to Applications à
- Launch Activity Monitor.
- Choose “CPU” tab and categorize by “% CPU.”
That is how a user can check the topmost items and if some processes are using a large amount of CPU. Just quit those processes.
When Third-Party App Is Your Strongest Weapon
Troubleshooting various Sierra problems is also possible with the help of a free/paid third-party software. Choose carefully an app that suits your demands. Download and install it using simple instructions. With the majority of such utilities, you can do the following:
- Detect large files that you can delete to reclaim disk space;
- Discover duplicates and other useless files;
- Remove the junk data from your Mac.
That is how you can get your Mac back to action!
