Some complained that their Mac would freeze for about 10 seconds every few hours.

This blog is intended to help you run your macOS High Sierra optimally and improve its performance without losing your valuable data. And if you have lost the data, read the blog further as we have shared a proficient macOS High Sierra data recovery software that will help recover your data from macOS 10.13 effectively and in easy to follow steps.

Increase the Performance of macOS High Sierra

Most Mac systems function seamlessly on the new macOS High Sierra, but a part of users face difficulty mainly because their system is not fully compatible to support the high functionality in the new OS. There are several issues that have been linked with the macOS High Sierra since its release like sluggish performance, data loss in certain cases, slow file transfer, external drive not mounting, and likewise. We have listed down some tips you can practice to resolve the issue with macOS High Sierra and optimize its performance.

Clean the Startup Disk

A storage device in the Mac that is full can be the cause of many problems like non-optimal performance of system, logical damage, and data loss. Therefore, frequent decongestion is advised to keep the hard drive healthy and the OS functional.

You can decongest the macOS drive using the two methods – automatic or manual. The manual process is time consuming as you have to identify each and every file that needs to be deleted from your Mac. To perform this function automatically, users may install a third-party software that identifies redundant files and removes them.

Leverage Optimize Storage

Optimize Storage is a marquee feature introduced in the macOS Sierra and is available in later versions. This subtle tool can make a world of difference to heighten the performance of your system as it automatically organizes files in an ideal manner. Follow the below instructions to easily access the Optimized Storage on your Mac.

Menu > About this Mac > Storage > Optimized Storage

After you toggle on the Optimize Storage option, it sends an instruction to the operating system to automatically organize files and also remove any unused, unread, or hidden files.

Free-up Memory and CPU Space

One of the primary reason that causes Macs to slow down after the macOS High Sierra update is the large number of applications running simultaneously that result in excess memory consumption, thus, slowing down the operating system. While some applications are necessary, there are others that run in the background consuming valuable CPU space. To resolve this issue with your Mac deploy Activity Monitor. Follow the below steps to easily access and set-up the Activity Monitor.

Access Applications > Utilities > Activity Monitor

Below the CPU tab, you can view the processor usage by various running applications. If you encounter a program with high memory consumption and no usage, stop that program.

Reconfigure SMC & PRAM/NVRAM

The System Management Controller (SMC) and Parameter RAM (PRAM) are essential tools that ensure your Mac runs optimally. SMC is responsible for most of the hardware functions like fans, battery, etc. Reconfiguring the SMC can resolve issues with your hardware such as battery fault, fault with the fan, and other issues. On the other hand, reconfiguring the PRAM will resolve problems related to screen resolution, booting, battery charging, etc. Follow the below steps to reconfigure your SMC and PRAM:

Reset SMC

  1. Shutdown the Mac
  2. Press the power button and hold down the ‘Shift + Control + Option’ keys
  3. Release all the keys to boot your Mac


  1. Shutdown the Mac, turn it on, and immediately press & hold Command (⌘), Option, P, and R
  2. In older Mac, hold down keys until you hear a start-up sound, else press and hold down the keys for 20 seconds
  3. Release the keys
  4. Open System Preference to ensure everything is properly reset
