4 Ways of How to Speed Up your iMac or Macbook Pro Significantly

Hey there!

I want to tell you how to speed up your MacBook, MacBook Pro or iMac today. If you notice that your Mac works a bit slowly, this article is definitely for you!

Before we start, I want to admit that there are two main reasons for such a slow work of your Mac. First of all, it can happen because of old hardware that can no longer cope with modern applications and works at its edge already. Second is overloading Mac OS X with different apps and unnecessary files cause such troubles.

Now, let's see what we can do with the Mac OS X to speed up your Mac.


How to speed up your Mac by removing all unnecessary apps from the autolaunch!

Firstly, use the Activity Monitor 

Find it icon  in 'Utilities'. Go 'Applications' -> 'Utilities' -> 'Activity Monitor' and see what applications load your system most.

Activity Monitor Mac Slow

The Activity Monitor window shows all the processes running on your Mac. Go to 'View' > 'Windowed Processes'. Click 'CPU' and tap the column with the same name to see apps that use your CPU. You can see what processes use your disk, memory, CPU and network.  

More and more applications add themselves to autostart while you use your Mac. So, they start automatically after the Mac launch. Hence, the more apps you have, the longer the machine will ‘wake up’. You can even not notice that they are open and keep them unclosed with no purpose while all of them will eat away lots of RAM. The less RAM is kept free, the slower your Mac works, keep that in mind.

So, how can we remove those apps (which we saw earlier in Activity Monitor) from autorun and speed up your Mac? Very simple! Just follow this instruction, or watch our video below:

  1. Tap the ‘Apple’ icon. It is in the left top corner.
  2. Go to the ‘System Preferences’.
  3. Click ‘Users & Groups’.
  4. Choose your username.
  5. Find the ‘Login Items’ tab at the top. You’ll find the list of starting apps there.
  6. Choose an app that doesn’t need to be launched automatically and tap the button with a minus on it. That will remove it from the autorun list.

Done! So, you can do these things to speed up your Mac at least a bit. Programs you really need to be launched immediately will launch with your Mac.


How to speed up your Mac by removing all unnecessary or junk files

After you’ve removed all redundant apps from autorun and made some RAM free, you can notice that the system started working a little faster, but we can try speeding it up even more!

Another reason for your Mac to be working sooo slooowly is the minimum amount of free space on your hard drive.

Very few people pay attention to it indeed. However, when there is a critical lack of free space, Mac starts to slow down catastrophically (literally). The cause for this is the fact that the operating system doesn’t have enough space for its stable functioning (saving the files cache, logs, different system files, and for working with different apps as well).

Please note that in general, this advice will be useful for owners of MacBooks with 128-256 Gb HD as they lack free space the most. Let’s see how to speed up your Mac by removing files.

I suggest removing these files:

  1. First of all, clean the trash bin as it usually accumulates tons of unnecessary files that can be deleted in one click.
  2. Next, I’d delete (or copy to another computer/external drive) old and large files that weren’t in use for a long time or ones that you don’t need anymore.
  3. Clean hidden trash, caches, plugins, logs, widgets, apps and language packs. These files can be found following the link:  ‘~/Library/Caches’ directory and its subdirectories.
  4. I’d recommend using an effective application for finding duplicate files. It’s called Gemini 2 and it’s free for download. This app can help you find and remove all the duplicates on your Mac. This feature would be especially useful for people who work with photo/video. I can bet that it will save hundreds of gigabytes!

After that, 25-35% of free space will appear and your Mac will start working noticeably faster. No more severe slowdowns!

If you want to achieve even better results (and it’s truly possible, indeed!), download and install CleanMyMac X (it’s free for download) and squeeze out the maximum benefits from this application.

One button click in CleanMyMac, and it’ll scan the whole Mac system and delete unnecessary waste. The free version deletes only 500 Mb. But, since I use CleanMyMac almost every day (for cleaning the Mac and its RAM), I decided to get a paid version with no limits.


How to speed your Mac by turning off visual effects

In general, most Macs can easily handle with Mac OS X Sierra. Still, some users prefer keeping the doc static in order to prevent slowdown. Go to 'System Preferences' > 'Dock' and remove ticks from these check boxes:

  • Magnification
  • Automatically hide and show the dock
  • Animate opening applications
  • Turn off accessibility

Tap on 'Minimize windows using' and choose 'Genie Effect' instead of 'Scale Effect'.


How to speed up your Mac with upgrading the OS and hardware in time

One more thing you should remember is timely updates for Mac OS X and its applications to their latest versions. Developers try to optimize the system, add new features, and fix bugs of earlier versions in the newest ones, so they work much better.

If you’ve done all the steps I suggested above and the speed of your Mac remains unsatisfactory, I'm afraid that It can be just outdated and requires a hardware upgrade. Or… Better sell your old Mac and get a brand new one!

In case you are going to upgrade your hardware, adding more RAM will help to achieve the maximum performance gain (here is the link to Amazon where you can look at the RAM price). Replacing a usual HDD with SSD (Amazon pricing) will improve the effectiveness of the Mac. Choose the best one that suits you by price and doesn't forget that you’ll pay an additional sum for replacing the old hardware with a new one. Or see how people do that on YouTube and do it yourself! In fact, there is nothing complicated and everything can be replaced in 30 minutes even if you don’t have a professional understanding of how it’s done. The main thing is having the right turn-screw! ;)

So, I’ve told everything I know on this topic. I hope, my piece of advice will help you in speeding up your Mac at least a little. Subscribe to my blog’s newsletters and don’t miss useful articles!
