MacOS High Sierra Slow? This is how u speed it up.

MacOS High Sierra was launched during the 2017 Worldwide Developers Conference. This is not a totally new OS but an upgrade of the current MacOS Sierra. as the name does suspected

after an upgrade it is a smart thing to clean your system so u can start kinda fresh. no u don’t lose any of your personal data 🙂

Oke, Lets start…

Step 1: Ensure the Mac You Have is compatible with High Sierra

Unfortunately, not all Macs are compatible with the MacOS High Sierra. The compatible ones are:

iMac (late 2009 and later)
MacBook (Late 2009 and later)
Mac Pro (2010 and later)
Mac Mini (2010 and later)
MacBook Air (2010 and later)
MacBook Pro (2010 and later)

Step 2: Update the MacOS High Sierra to the Newest Version

New operating systems come with more features that help them run smoothly and fast. To quickly fix High Sierra Slow look for updates and install them. To find updates for the High Sierra, open the Apple App Store on the Mac and in the toolbar click on check for Software Updates. If they are there download and install them by clicking on the “Update” button.

Step 3: Clean Up the Hard Drive

The hard drive is where all the data you store in your Mac goes. From the system files that make it run to all your personal files

with CleanMyMac 3 u can easy clean up all the unwanted files on your Mac.

Step 4. Use the Optimized Storage Upgrade Feature

This is maby one of the best functions of a Mac It is a feature that allows the Mac to automatically organize files. How cool is that.

U can find this option by going to the Apple logo on the left top of your screen –> About this Mac –> Storage –> Manage…

Setting the optimized storage upgrade on instructs the Mac to clean up files and free disk space. also let your Mac clean up the trash automatically, this things can add up.


Step 5: Manage Start Up Items

One of the most common reasons for High Sierra and any other operating system running slow is having too many start up Applications. this will start up while your Mac is booting.

To disable startup programs

1. Navigate to “System Preferences” then “Users & Groups” then “Login items.” there is a possibility that u need to unlock the lock to make changes..
2. Select the apps you would like to stop from loading at startup.
3. Click on the “-“ button. This removes the apps and they will no longer slow the Mac down.


Step 6: Reboot.

As last and final step, just reboot your Mac or even shut it down and remove the power cable (in case of iMac) just wait 5 minutes and boot it again.

One thing to remember. make sure that the “Reopen windows when logging back in” is UNchecked
