Even though OS is often treated superior over Windows, Linux, and the others, it does not mean that it is going to work in a fast and smooth way forever. There are various factors that influence system’s performance, including the number of apps on the system, temporary files, startup programs, disk space, the old of OS, etc. Although Mac OS is deemed as being faster than Windows, inappropriately maintained Mac can also start working abnormally and slow down significantly. Therefore, once you notice that the system works slower, optimize your Mac and enjoy its best performance again.

How to Increase Mac’s Speed?

Optimize now! Optimize now!
Unique technology of Reimage recovers system with fresh files and can seriously revive the life of your machine. The free scanner will let you know which parts of your system need to be optimized. To restore your computer's peak performance, you have to purchase licensed version of Reimage Reimage repair software.

Cleaning up Mac’s hard drive would be a great start.

We would recommend installing one of these programs, i.e. MacKeeper or MacCleanse and let them clean up the drive. Both programs are capable of removing junk, optimizing startup items, removing system plug-ins, rooting out the leftovers of the removed apps, and similar things. These programs should be second software after malware removal tool because without one of them the system gets burdened with useless and outdated files. Thus, download a program you prefer and follow the instructions how to use it.

Find out which processes ‘eat up’ the most of Mac’s power.

All Windows users know well what the Task Manager is. It allows monitoring what processes are running in the background of the system and how much CPU they are using. The same can be done on Mac OS using Activity Monitor function. To launch it, you have to open Spotlight search by clicking Command + Space. Type Activity Monitor in the search bar and press Enter.

To see how much CPU each running program consumes, click the % CPU. This selection will automatically sort out the running processes according to the power consumption. There might be a single or several process taking up the majority of CPU, so to speed up your Mac, force these applications and processes to quick. For that, select the process of high-CPU usage, click on it and then press X button on the toolbar.

NOTE: make sure that the process you are going to quit is not run by an important app.

Close unimportant applications.

If you have noticed Mac’s slowdown, one of the primitive ways to speed it up is to close applications that are not necessary. It’s not a secret that Mac OS X tends to leave running apps in the dock. In other words, even clicking the X (close app button) does not disable the app completely because it keeps active in the background. That’s OK, in fact, unless you see that system’s performance has decreased.  In this case, locate apps marked with a dot on your dock, right-click on it, and select Quit.

Minimize the number of Startup Programs.

Imagine how much work your Mac should perform each time when logging in if there are too many default startup programs. That’s yet another issue that you should check in order to optimize Mac’s performance. Luckily, it’s not difficult to manage statup programs. For that, you have to:

  • Click Apple menu icon – select System Preferences.
  • Click on the Users & groupsyour current user accountLogin Items.
  • Uncheck the apps that are not necessary for log in.

Reduce Animation & Transparency.

It is known that animation and transparency tend to burden graphics hardware on Macs, typically older ones. Therefore, to increase Mac’s speed, reducing them might help. Thus, Navigate to System Preferences – click Accessibility – check Reduce transparency. If you are using OS X Yosemite on an older Mac, this solution may increase system’s speed more than you expect.

Try another web browser

Would you believe if we’d say that your web browser may the core problem causing Mac’s slowdowns? Probably not. Nevertheless, it you are using Chrome particularly, you should better believe this. Google Chrome consumes an enormous amount of CPU on Mac OS X, which is why it is not recommended using on this software. Well, of you tend to browser on one single tab, you might not feel Mac’s slowdown, but the more tabs you open, the more resources the browser uses. In some of the cases, running Google Chrome may take up 99% of CPU. Therefore, you’d better try Safari browser.

Disable FileVault Disk Encryption.

This Mac’s function is extremely handy in case if you lose your Mac. FileVault Disk Encryption does not allow other people to sign in without your approval, as well as prevent access of the others in case of theft. However, researches have shown that FileVault Disk Encryption tends to diminish Mac’s performance, so if you need to speed it up, try disabling this function. Well, at least for a short time. For that, you have to:

  • Navigate to System Preferences – click Security & Privacy – select FileVaultFileVault disk encryption off.

Free up Disk Space.

To check how much free space there are on your Mac, click Apple menu, select About This MacStorage. If it turns out that there is no much of free space left, you should consider freeing it up.

Reinstall Mac OS X.

If you have tried various tips on how to speed up Mac OS, but nothing helped, maybe it’s time to think about reinstalling OS? If you have backups of important files, then it’s more than simple to do that. Boot into a recovery mode and start the installation. In contrast to Windows OS, Mac OS downloads everything that is needed automatically from Apple.
NOTE: before reinstalling Mac OS X, make sure that you have backups. Otherwise, you may be in a very serious trouble.
