mac system performanceTechnologies change and become better, smarter, and faster in a blink of an eye. And one day a device claiming to be the top of the mind turns out to be nothing but a museum showpiece.

When it comes to computers, the things are even more dramatic. And no matter how awesome your brand new Macbook was yesterday, glitches and overall slowdown may become a reality of today. Fortunately, there are ways to bring your computer back to life and make system operation better.

Reasons for Slow Mac Performance

Before getting to our improvement tips, let’s puzzle out why on Earth your laptop slows down one day.

  • Cache Issue

The first reason is caching. When running, the system saves files for smooth operation of applications. Sometimes these files remain in the system even after an application is closed or deleted. Such needless junk files are the ones that lead to your Mac running slower.

  • Hardware Issue

The second reason is concerned with hardware. Each day software becomes more and more resource taking. It consumes a lot of memory space leaving your computer with almost nothing to maintain smooth operation.

Important: remember to make a backup before implementing any system performance interventions.

How to Improve Mac Performance after a Slowdown

1) Detect Procedures that Eat to Many Resources

The Activity Monitor tool on your iMac will let you monitor all running processes and detect those that consume most of all. Sometimes it happens that a runaway app takes like 90% of all Mac’s operation capacity. Which leads to a system slowdown.

Check ‘% CPU’ under Activity Monitor and shut down apps you don’t use now but see that they consume a lot.

2) Close Applications You Don’t Use Now

One of interesting peculiarities of Mac OS X, it doesn’t always close apps after you actually close them. It means that even if you clicked the close button an app might still be running in the background slowing down a system a bit.

Check your Dock and find applications marked with dots. If you see that one of them is running while you don’t use it, right-click on it and ‘Quit’.

Sure, in most cases it’s not a big issue. But if you do want to boost your OS X performance, you should consider this one as well.

3) Reduce the Number of Startup Apps

Too many apps launching when you turn on your device may also slow it down. Open ‘System Preferences’, go to ‘Users & Groups’, select your account, and click on ‘Login Items’.

There you will see all the application that launch at login. If you don’t really need some of them it would be better to remove them. Uncheck those needless apps.

And vise versa, if you want some programs to run as soon as you turn on your computer, add them in the same place by either clicking the ‘+’ button or simply dragging and dropping an app there.

4) Clean Up Your Device

There is software that runs without you knowing and files saved you don’t know where. It’s hard to find it all, close it all or delete. For such particular purposes there are different applications. They keep track of all activities connected with your device’s work and can help you prevent your computer from wasting its capacity on maintaining needless processes.

5) Reduce Animations and Transparency

Macbook OS X looks really cool thanks to all these animations when windows open or close, transparent elements and other stuff. However, maintaining it all also consumes your powers of your computer.

To make it work faster, go to ‘System Preferences’, select ‘Accessibility’ and check a ‘Reduce Transparency’ option.

Changing ‘Genie effect’ to ‘Scale effect’ will also boost your Mac’s performance a bit. As a result window minimizing and maximizing will run much faster.

6) Consider Your Web Browser

Even though Mac OS provides users with its own web browser – ‘Safari’, many of them prefer Chrome. But very few of them really know that Chrome works slower on iMac than Safari does. Moreover, its extensions reduce Mac’s performance and make a battery run down faster.

7) Disable FileVault Disk Encryption

FileVault really make life safer for you and your computer. On the latest OS X it is enabled by default. However, it also doesn’t let the system start as quickly as it could. Thus, if you go to ‘System Preferences’ > ‘Security and Privacy’ and disable FileVault, you will make your mac boot faster.

Note that if you don’t face any loading slowdown when turning on you device, you’d better keel FileVault enabled. Safety is above everything after all.

8) Make Finder Work Faster

When you click on Finder it opens all your files by default. If you have a lot of them it make a take a while until it loads up everything. That’s why another good how-to speed up mac performance is to choose another folder to be launched when Finder is open.

Go to Finder and open its preferences menu. There you will see ‘New Finder Windows Show’, where you can choose an initial folder.

9) Free Up Disk Space

This one is the most obvious recommendation. Since the less memory space your computer has on its command, the slower it works. Go to the Apple menu and ‘About this Mac’. If you see that you’re running out of space, delete as many needles files as you can.

Sometimes it’s hard to decide which files are really needles and which ones you should better leave. Different would be of help here.

10) Reset SMS

This can really fix a computer performance slowdown and many other problems. Don’t be afraid, resetting System Management Controller won’t delete any data. It will serve only as a low-level reboot for all the system of your computer.

Bonus Tip to Increase Mac Performance

11) Reinstall Mac OS X

If after trying all the aforementioned tips you keep noticing that some issues still slow down your iMac performance, reinstall your OS X from scratch. It works in all cases for all devices of all times.
