2. Clean Hard Drive on Your MacBook

Unlike the human brain that constantly deletes old and unnecessary data or files by itself, the Mac never automatically removes its data. The flaw of this design is that over time the limited space hard drive becomes congested and even filled up if nothing is ever deleted, hence frequent decongestion is advised.

Decongestion can be achieved via two methods, either manually or automatically. Manually, a user can go through the rigorous process of searching for and identifying all redundant files and documents on his device and delete them manually. However, compared to the automatical way, this is rather time and energy consuming.

Referring to tools such as Umate Mac Cleaner that could really help, which can automatically identify redundant and hidden files and then delete them, freeing up space on your hard drive to improve Mac's functionality and performance.

3. Activate the Optimize Storage Option on Your Mac

4. Decongest Your Mac Memory and CPU Space

A major reason for your slow Mac after its High Sierra update is that numerous applications are running simultaneously to consume vital CPU space so that the system slows down. When some applications run actively, others run in the background and also consume considerable space. To recover memory space and resolve this issue, we need to deploy the Activity Monitor.

Access Applications > Utilities > Activity Monitor

Under the CPU tab, you would see the distribution of CPU usage among the currently running processes. Should you identify an application that is not necessary but is consuming considerable memory space, be swift to eliminate it by tapping it and hitting the close button at the top-left corner of the screen. Unwanted apps can also be toggled off to save Memory.

5. Reconfigure SMC & PRAM/NVRAM

The System Management Controller (SMC) and parameter RAM (PRAM) are important tools in ensuring the smooth functioning of the Mac. Reconfiguring the SMC resolves all hardware management issues like fans or battery faults and so on. While reconfiguring the NVRAM handles issues like pertaining to booting, screen resolutions and battery charge, etc.
