Many people upgrade from their Mac OS X to macOS Sierra or High Sierra to obtain more exciting features and improved performance. However, immediately after the upgrade, the user may experience an insignificant slowdown in the system.

It is critical to understand that Mac’s processor does not rely just on RAM for memory. When the dire need appears, the processor will most probably switch to the partition on which Sierra is set up. In case this partition is fed up with useless items, there is a big opportunity that the Apple computer will surrender to a crawl unless you take care of the garbage. Here are the reasons to get macOS Sierra on your computer:

  • Available Night Mode;
  • 2016 MacBook Pro with Touch Bar will benefit;
  • Issues with Mac OS X versions;
  • Higher security;
  • Perfect for Siri;
  • Better work of messaging apps + new emoji;
  • Good for Apple Pay;
  • Ability to unlock the Apple Watch;
  • The increased amount of disk space.

The last point automatically guarantees boosted performance as it basically depends on the speed of work, and Macs only work fast when they have at least a bare minimum of storage space (at least 10-15%).

Be ready that a system will turn into a sloth only after the installation and each time the hard drive is filled. During the installation process, Spotlight may want to index the entire hard drive to find out everything stored on the drive. It will allow discovering the necessary information and files in the future, so this one-time procedure is worth waiting.

macOS Sierra Performance Review

macOS Sierra Performance

Memory Checkup

Mac’s memory is a huge part of the overall performance. Thus, you should start by measuring it once you notice a drop in the speed of work and productivity. To find the root of all evil and decide on your further actions (e.g., system cleaning):

  • Go to the Applications Folder.
  • Pick Utilities there.
  • Choose Activity Monitor.
  • Select Disk Usage.

In case you simply wish to check the amount of available and used RAM< pick the Apple menu and find “About This Mac” option.

To objectively evaluate the work of your macOS Sierra, it is important to consider several categories.

Hard Drive and SSD Performance

Estimate the read-write speeds of the hard disk drive or SSD. Apply various third-party tools like Blackmagic Disk Speed Test (it is free after all). Get something like that from the App Store and install on your device. Most of such tools are simple to use.

Launch the checking app, pick the drive of your interest (or several of them) and begin the scanning procedure. It will take from several seconds to a minute. It depends on how overloaded the target disk is. Check whether no applications or processes are running at a time, as it all affects the performance negatively. Pay attention to the read/write scores on different disks. After that, pick the disk with the better indicators for more complicated tasks like displaying HD videos or 3D games.

If you have no interest in running big files like videos, pay attention to the single indicator shown in the large gauges at the top of the tool’s screen. A user can see the write speed on the left, whole the read speed is on the other side.

How should a Mac owner understand if the device’s performance is okay or below the expected? Mind that a typical external drive connected to the Apple computer with the help of USB 2.0 does not show a speed better than 30MB/s. Right, it is quite smooth, but that is a user decision. Try switching to a solid-state drive (SSD) to increase macOS Sierra speed.

Graphical Performance Benchmarking

Take some piece of software like Cinebench. It is free of charge. The application examines a computer’s CPU (you may compare and contrast the results online) and applies a special test to check the graphics card performance. This procedure will observe how GPU copes with about a million polygons per time when mixed with some extra effects.

Performance Improvements: Happy User Check-List

User Check-List

Review this checklist and make sure everything is done properly to boost the performance of macOS Sierra. All of these steps require little time and almost no financial investments (most are free of charge).

  1. Try rebooting the device in case of any system slowdown. This action will wipe the caches and close the running apps.
  2. In case of a smooth boot up process, take care of the Login and Startup items. Delete some applications and processes that launch at the beginning without any permission.
  3. Try to clean up the hard disk drive. It is possible to save time thanks to the numerous third-party apps.
  4. Make sure that you have shut down the unnecessary apps and services. Tip: Clicking the X button is not a 100% working solution. It means the person has simply closed the corresponding window. In order to escape, pick “Quit” option by right-clicking.
  5. Launch Activity Monitor to detect the culprit and eliminate the process/app, which ‘eats’ a lot of memory and space.
  6. Decide whether you really quitted the useless tabs/windows on the preferred browser. It may be the cause of the slowdown in the work of Mac’s Safari, FireFox, or Chrome. The Internet might start working faster after closing the mentioned items.
  7. Check whether FileVault is on or off. It is one of the primary causes of slow startup. Ignore this step in case data encryptions matters to you more than performance.
  8. It is better to switch off the visual effects even though they make the monitor look exciting. Many Mac owners simply love the Genie Effect, but they have no idea how harmful this element could be to their devices. To disable the effects, move to System Preferences and Dock.
  9. Erase the files and folders on Desktop or at least categorize them somehow.
  10. Check the list of applications on your Mac. Completely uninstall those you have not used for a while.
  11. Each time you throw anything o the Trash bin, its leftovers and the ore file remain in the system until you Empty Trash.
  12. What about the browser’s cookies, caches, plugins, and history? Delete these elements to notice a significant boost in speed as well.
  13. Detect the duplicates of various videos, images, audios, and other files. Why would you need to keep the clones of various items on your Mac? Remove the duplicates once and forever!
  14. Make sure to deactivate the notifications you do not need any longer. Continuous messages have a negative impact on the overall performance.
  15. Do not forget to run all new available software updates. It will prevent the utilities from freezing.
  16. Examine the work of a wireless network.
  17. Get rid of the system preference panes you do not use.
  18. Move the files you still need but regularly use to iCloud.

If you fin various manual methods a waste of time or in case the third-party cleaners do not really help to achieve the expected results, just increase the space storage with the help of external hard drives. Experts recommend purchasing SSDs to improve the speed significantly!
